what is lubrication in biology

Studies on sexual behavior allow us to intertwine data and theories that incorporate biology, psychology, and sociology. The effect of spironolactone, in combination with other medications, on recurrent atrial fibrillation has been evaluated in 164 consecutive patients, mean age 66 years, in a randomized 12-month trial; there was gynecomastia in three patients who took spironolactone; the plasma potassium concentration did not change significantly [67]. Spironolactone causes breast tenderness and enlargement, mastodynia, infertility, chloasma, altered vaginal lubrication, and reduced libido in women, probably because of estrogenic effects on target tissue. Rules can be helpful in guiding people to learn more effective bedroom techniques, relationship skills and much more. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Then, for about 2 or 3 sec before the sacral reflexes cause contractions in the pelvic muscles at 0.8-sec intervals, women report the onset of pleasurable experiences (at the time when males feel the pleasurable sensation of ejaculatory inevitability). Ricardo Munarriz, MD, Noel N. Kim, PhD, Irwin Goldstein, MD and Abdul M. Traish, PhD. This phenomenon can result in major fluctuations in the composition of the microbial population in the soil. Isolated tissue bath studies in which myogenic and neural factors can be modulated are useful for understanding the neural and pharmacological mechanisms mediating tissue contraction and relaxation. The primary punishers of pain help us learn to avoid hurting our ovaries and testicles when possible. Social reinforcement for exploring sex with others can occur when a child's peer group rewards taking a dare about some sexual activity. The pleasurable feelings of the sexual reflexes can be associated with all sorts of stimuli via Pavlovian conditioning. In these circumstances, a lubricant can help. A young man who masturbates while watching pornography is pairing new stimuli with the sex reflex, and he may end up feeling sexually excited by seeing or thinking about such activities in the future. After 12 weeks, in comparison with the placebo group, the E group reported significantly more sexual fantasies, better lubrication, less coital pain and more sexual enjoyment. J.D. Understanding the peripheral and spinal mechanisms mediating genital sensations and arousal is not only important for helping understand decreased genital arousal disorders, but is essential for development of treatments to aid women with persistent genital arousal that can cause severe distress in women.2,136,137, Vaginal dryness can occur concomitant with chronic disease; e.g., with diabetes mellitus, hypertension, and after spinal cord injury. A potential source of bias in these results came from the higher rates of withdrawal due to treatment failure in those taking eplerenone (20%) compared with spironolactone (4.2%). Found inside – Page 388Lubricants are substances, either organic or manufactured, that assist in the reduction of friction between surfaces that come in contact with one another. Lubricants are useful in many sexual situations. Men produce a natural lubricant ... Hence, the sex reflexes are quite different from such quick S–R reflexes as the patellar knee jerk or jerking away from electric shock. Biology Assignment Help, Explain water as a lubricant, Explain Water as a lubricant? This contributes to a commonly observed gender difference in the activities that males and females gravitate toward. STUDY. If he asks his girlfriend to do some of the things shown by the porn videos, his girlfriend may be happy to oblige; but some girlfriends are surprised that their boyfriends would even think about enacting porn scenes, and this can create problems for the couple. Ricardo Munarriz, MD, Noel N. Kim, PhD, Irwin Goldstein, MD and Abdul M. Traish, PhD. Of 168 patients with mild to moderate heart failure (NYHA class I–II) and left ventricular ejection fraction 40% or less who were randomized to spironolactone mean dose 52 mg/day or placebo, spironolactone was withdrawn in two patients with gynecomastia and breast tenderness [30].

What is the tough layer that protects the route as it forces its way through the soil and provides a lubrication for route to travel. Starting from birth, the sexual reflexes in the lower spinal cord send signals to and receive signals from the brain. During the plateau phase of the sexual response, the thoracic and lumbar reflexes produce increasing vasocongestion, which augments vaginal lubrication. Lubrication, introduction of any of various substances between sliding surfaces to reduce wear and friction. Movies, DVDs, books, and the Internet make it easy to learn about sex, although not all the information is accurate. As with SCI, hypersensitivity or dysesthetic pain does not respond well to medications, though anecdotal reports support the use of tricyclics or venlafaxine. A unified overview of the dynamical properties of water and its unique and diverse role in biological and chemical processes. The brain can (1) sense inputs from the genitals and sexual reflexes and (2) cause sexual responses in the genitals. lubrication mechanisms, including fluid-film, boundary or mixed lubrication regime as well as the biphasic lubrication mechanism specifically proposed for … Found inside – Page 343Ocular lubricants are used on a frequent basis to alleviate dry eye symptoms and signs. Ocular lubrication can be further increased by the insertion of small plugs (punctal plugs) into the lacrimal punctae of the upper and lower eyelids ... Vaginismus indicates the persistent or recurrent difficulties of the woman to allow vaginal entry of a penis, a finger, and/or any object, despite the woman's expressed wish to do so (Basson et al., 2004; Graziottin et al., 2004; Graziottin, 2006a; Graziottin and Rovei, 2007). Found inside – Page 485It is compatible with fluid - film lubrication , mixed lubrication , and boundary lubrication , to the extent that all of these modes of lubrication may serve to enhance the role of interstitial fluid pressurization . These muscle contractions force the ejaculate out of the male's body at the time of orgasm, and they cause orgasm to be experienced as rhythmic pulses or surges of pleasure. This shows grade level based on the word's complexity. Match. This article began by stating that a developmental perspective on sex is theoretically valuable, and we can now explain why. In addition to the enzymes and hormones that … There is often (phobic) avoidance and anticipation, fear, and experience of pain, along with variable involuntary pelvic muscle contraction. Praise for the previous edition: “Contains something for everyone involved in lubricant technology” — Chemistry & Industry This completely revised third edition incorporates the latest data available and reflects the knowledge of one ... The only exception is vulvodynia in children or virgin adolescents, or in women of any age who do not have penetrative sex for a number of reasons. Bio-based lubricant formulations present a promising solution. Biolubricants: Science and technology is a comprehensive, interdisciplinary and timely review of this important subject. If he asks his girlfriend to do some of the things shown by the porn videos, his girlfriend may be happy to oblige; but some girlfriends are surprised that their boyfriends want to try some of the aggressive activities depicted in porn scenes, and this can create problems for the couple. 7 The resultant vaginal transudate is mainly composed of water and very small proteins, which combine at the vaginal surface with . Even if he does not masturbate while viewing porn, he may think about the pornographic images when he masturbates at a later time, thereby sexualizing those stimuli. After this brief preejaculatory period, reflexive control is transferred to the sacral reflexes, which now cause rhythmic muscle contractions around the base of the penis (inside the body), starting at intervals of 0.8 sec and then gradually slowing to longer intervals. Female sexual dysfunction in diabetic individuals, e.g., manifests in inadequate vaginal lubrication which is independent of depression.139,140, During sexual arousal fluid is secreted through the vaginal wall. In the vast majority of cases, however, coital pain is a powerful trigger of personal and relational distress. Young infants can learn how to masturbate, even though they cannot put words on the behavior or think about it in symbolic terms. Once children begin to use language, they can take verbal information and use it as ‘rules’ to hasten operant learning. Social reinforcement for exploring sex with others can occur when a child's peer group rewards “taking a dare” about doing some sexual activity. But this is only a small portion of the difficulties that must be overcome in cylinder lubrication. a. Why Do “Left” And “Right” Mean Liberal And Conservative? Because salivation helps start the digestion of food, dogs (and many other species) have evolved to salivate when they smell food. | Meaning, pronunciation, translations and examples The pleasurable feelings of the sexual and intimate activities can be associated with all sorts of new stimuli via Pavlovian conditioning. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Blood pressure pushes fluid from the capillaries through intracellular gap junctions between vaginal epithelial cells.7 The resultant vaginal transudate is mainly composed of water and very small proteins, which combine at the vaginal surface with dead epithelial cells. Appropriate tactile stimulation to the genitals first activates parts of the sacral reflex mechanisms (in the lower vertebrae of the spinal cord). Competition is the injurious effect of one organism on another because of the removal of some resources of the environment. Gradually, the genitals return to the relaxed condition seen before the onset of sexual stimulation. Changes in specific oscillations of blood flow have been recorded in both rat and human vagina.156,157 In women, the oscillatory patterns correlated with subjective arousal and not genital arousal. During a critical period of fetal development, boys' testicles produce a burst of prenatal testosterone, which alters their brains in ways most females do not experience. Social attention is often a reinforcer. Women with lesions involving the sacral spinal segments may maintain the capacity for psychogenic lubrication while losing the capacity for reflex lubrication (Sipski, 1995b). Much of our behavior is learned by observing others, and sex is no exception. The application of a substance to diminish friction between two surfaces. Bilateral painful gynecomastia that occurred after treatment with spironolactone 100 mg tds for 2 months in a 54-year-old Caucasian man resolved within 1 month after treatment was switched to eplerenone 25 mg tds [62]. It may refer to oils, greases, and similar substances for the lubrication of medical equipment but it can be used for the application of substances to tissue to reduce friction, such as lotions for skin and vaginal lubricants. Pavlovian conditioning allows inborn reflexes to be linked with new stimuli in ways that we did not evolve to experience. Baldwin, in Encyclopedia of Human Behavior (Second Edition), 2012. Terms in this set (62) What is the reagent to protein?

Sufficient pelvic blood flow is dependent on the bioavailability of nitric oxide (NO).4 Gaseous NO is produced in capillary endothelia in response to shear stress or vibration or in response to sexual arousal via parasympathetic nitrergic nerves.9 Once produced, NO induces vasodilation through a cyclic guanosine monophosphate (cGMP) cascade, which diminishes as phosphodiesterase enzymes subdue the effect. Where is the zone cells divide. PLAY. Infants have no intentions of discovering sexual pleasure, but when early random explorations lead to pleasing feelings, positive reinforcement increases the chances that, on later occasions, exploring infants will repeat those types of self-stimulation that were pleasurable in the past. Found inside – Page 367natural resources have to be considered, as well as high performance in lubrication.

This phenomenon can result in major … A number of studies of the symptoms of either natural or surgical menopause, reviewed above, have either taken women on E replacement, who continue to have loss of sexual interest or response, and evaluated the effect of adding T, or have compared E replacement with a combination of E and T, or T alone. A young woman who pays attention to her boyfriend's hairy chest while having sex may come to find hairy chests to be a sexual ‘turn-on’ or ‘erotic stimulus.’ Later she may notice that she becomes sexually aroused when she sees other men who expose hairy chests. For example, it is easier for males than females to learn to love rugby and downhill mountain-bike racing, and they may also prefer more active sexual activities than do females.

From: The Journal of Sexual Medicine, 2010, Myrtle Wilhite MD, MS, in Integrative Medicine (Fourth Edition), 2018. The vagina contains no glands. The simplest way to integrate all the elements that shape sexual behavior is to follow a developmental time-line that starts with birth and traces the following decades of maturation, learning and socialization. Lubrication Meaning. If a teen frequently hears about the importance of using condoms to reduce the risks of becoming pregnant or contracting sexually transmitted diseases, the words can serve as rules that help the teen avoid the errors that too many young people still experience through “trial-and-error” learning. From infancy, stimulation of the genitals activates these reflexes – causing the sexual organs to swell – and elicits pleasurable feelings in the reinforcement centers of the brain. Created by. It changes in texture, color, and consistency, depending on your cycle . Lubrication is the control of friction and wear by the introduction of a friction-reducing film between moving surfaces in contact. Lubrication and protection. A young woman who pays attention to her boyfriend's hairy chest while having sex with him may come to find hairy chests to be a sexual “turn-on” or “erotic stimulus.” Later she may notice that she becomes sexually aroused when she sees other men who expose their hairy chests. Water-based fluids act as lubricants in various parts of the body, most notably within joints where synovial f Match. Cervical fluid is made up of carbohydrates, proteins, and amino acids, and it is the most informative of the vaginal fluids. hcps-millermc. Found inside – Page 537Unless the leak is slow , the increase can be observed on the manometer while the reading is being taken . The cause of a leak is usually improper grinding or lubrication of cock b ( Fig . 1 ) . Lubrication . Reinforcers explain why an infant's early random touching of the genitals can become more frequent and eventually a habit. Approximately 30% experience decreased genital sensation and an equivalent number report impaired lubrication (Dachille et al., 2008). Gravity. Although this is a valid definition, it fails to realize all that lubrication actually achieves. The sexual orientation of lesbians appears to be about 25% heritable. In a prospective study of the effect of spironolactone on atrial remodeling, 110 patients with preserved left ventricular function who had an acute myocardial infarction were randomized into two groups: conventional therapy (n = 55) and additional spironolactone 25 mg/day with standard conventional therapy (n = 55) [65]. Hybrid lubes, like Babeland's BabeLube Silk ($10-24), are often a … Firstly, through lamellar … In rats, slow oscillatory vaginal blood flow patterns were modulated by both autonomic and central mechanisms. Lubrication The application of a substance to diminish friction between two surfaces. In summary, both biology and learning are important in the development of sexual behavior and both are intertwined starting from infancy. oil. The Internet, sexually-oriented magazines and books provide many instructions for exploring sex. The pleasurable feelings associated with sex serve as reinforcers that can strengthen behavior, through a process called operant learning. No fire engine reds here, only a fierce collection of vibrant words for the color red to test yourself on. There are ‘primary punishers,’ too; and they are also biologically ‘wired in.’ Hitting the testicles or ovaries is painful for biological reasons: it endangers these important reproductive organs, and we have evolved to find such experiences aversive. After this 2- to 3-sec period, females begin to experience the rhythmic surges and pulses of orgasmic pleasure that occur as their genital muscles begin to contract at intervals of 0.8-sec, gradually slowing to longer intervals. protection, lubrication, recognition, and adhesion Ligands Bind with cellular receptors to activate or inhibits the receptor's associated signaling or biochemical pathway Importantly, the presence of NO is not sufficient for its effect. Having positive consequences strengthens the habits of continued rule use. sexual reproduction. Vaginal lubrication is reliant upon healthy blood flow because vaginal lubrication is ultrafiltrated blood.. Learn. The application of a substance to diminish friction between two surfaces. All fluids have lubricating as they can make it easier for the solid materials to slip over one another. Lubrication. Competition is the injurious effect of one organism on another because of the removal of some resources of the environment. Vaginal lubrication is an indicator of tissue health and increases significantly during genital sexual arousal, facilitating sexual intercourse. Lubrication. To further understand tribology, it is important to understand the definitions behind friction, wear and lubrication. Female sexual dysfunction is defined as … Vaginal lubrication is a naturally produced fluid that lubricates a vagina.Vaginal lubrication is always present, but production increases significantly near … The primary punishers of pain help us learn to avoid hurting our ovaries and testicles when possible. As we have already seen, social punishment can occur when caregivers punish a child for masturbation; and the stronger the punishment, the more inhibitions it produces. Both biological and learning processes are involved in the gradual emergence of sexual behavior, and developmental studies reveal how nature and nurture interact and entwine with each other. The study of lubrication is a … People's location in society also affects their thoughts, emotions and behaviors. In this article, an overview of the biology and engineering Sometimes, women just prefer more lubrication than their bodies provide. Sildenafil, in doses of 50−100 mg, has been reported to improve sexual satisfaction in women with MS (Dachille et al., 2008). Touch of these structures, with the appropriate pressure and patterns of movement, activates the spinal reflex centers, and continued stimulation produces a long chain of several distinct responses––called excitement, plateau, orgasm, and resolution––that often take from 2 to 20 min for a person to experience all four of these phases. What is the function of hydrochloric acid? By continuing you agree to the use of cookies. From infancy, stimulation of the genitals activates these reflexes, causing the sexual organs to swell and eliciting pleasurable feelings in the reward centers of the brain. In 19 patients with hepatic cirrhosis who had taken spironolactone and developed painful gynecomastia, substitution of spironolactone with eplerenone for 3 months resulted in reduced breast pain [69]. Vaginal dryness is common in postmenopausal women, and can be reduced by the use of topical or systemic estrogens in women, who have no medical contraindications to gonadal hormonal treatment—i.e., women with estrogen receptor-positive breast cancer would need to be treated with nonhormonal agents. There are “primary punishers,” too; and they are also biologically “wired in.” Hitting the testicles or ovaries is painful for biological reasons: It endangers these important reproductive organs, and we have evolved to find such experiences aversive. •Cargo receptors bind to the cargo ( most likely protein) … Found inside – Page 24When the joints are in motion, these large forces produce frictional wear, which could be damaging unless the joints are well lubricated. Frictional wear at the joints is greatly reduced by a smooth cartilage coating at the contact ends ... in cartilage lubrication in native tissues has pushed the pendulum and warranted a shift in the articular cartilage tissue-engineering paradigm. Much of our behavior is learned by observing others, and sex is no exception. Right atrium right ventricle left atrium left ventricle.

Tribology is the study of the science and technology of interacting surfaces in relative motion and encompasses the study and application of … As we have already seen, social punishment can occur when caregivers punish a child for masturbation; the stronger the punishment, the more the inhibitions it produces. Humans are capable of only one mode of reproduction, i.e. This contributes to a commonly observed gender difference in the activities that males and females gravitate toward. By adolescence, males tend to prefer stronger tactile stimulation of the genitals than do females, but both males and females have thresholds beyond which additional stimulation elicits pain. Sympathetic pathways also play a major role in regulating female genital arousal by modulating the tone of vascular and nonvascular smooth muscle (via α1/2-adrenergic receptors). Because salivation helps start the digestion of food, dogs (and many other species) have evolved to salivate when they smell food. Last updated on July 21st, 2021. Vaginal lubrication is a naturally produced fluid that lubricates a vagina.Vaginal lubrication is always present, but production increases significantly near ovulation and during sexual arousal in anticipation of sexual intercourse.Vaginal dryness is the condition in which this lubrication is insufficient, and sometimes artificial lubricants are used to augment it. PLAY. Lubrication is the process or technique of using a lubricant to reduce friction and wear and tear in a contact between two surfaces. We have already given descriptive information about several features of prepubertal sexual development. The heart helps make red blood cells. The oils used for cylinder lubrication are obtained almost exclusively from crude petroleum derived from American wells. Cervical fluid is made up of carbohydrates, proteins, and amino acids, and it is the most informative of the vaginal fluids. There is a great deal of variation in optimal activity levels in both males and females, but males tend to prefer higher activity levels than females do. The pleasures of genital stimulation are called “primary reinforcers” to indicate that they are biologically “wired in” as part of the sexual reflexes. Wallen has strongly advocated that the sexual effects of T in women result from the consequent increase in free E, supporting this conclusion with experimental data from Rhesus monkeys (Wallen & Parsons 1998). This avoids surface wear by impeding the direct contact of surfaces (Hsu and Gates, 2000). Withdrawal rates because of adverse events were similar. This difference may be related to structural characteristics unique to metabolites of spironolactone, namely a thiol group at the 7-alpha position [60].
