Biological meaning of sexuality


Human sexuality is the way people experience and express themselves sexually. Social aspects deal with the effects of human society on one's sexuality, while spirituality concerns an individual's spiritual connection with others. Sexuality also affects and is affected by cultural, political, legal, philosophical, moralethicalBiological meaning of sexuality religious aspects of life.

Interest in sexual activity typically increases when an individual reaches puberty. Some argue that Biological meaning of sexuality is determined by geneticswhile others believe it is molded by the environment, or that both of these factors interact to form the Biological meaning of sexuality sexual orientation.

In the former, one assumes that the features of a person innately correspond to their natural inheritance, exemplified by drives and instincts; the latter refers to the assumption that the features of a person continue to change throughout their development and nurturing, exemplified by ego ideals and formative identifications.

Evolutionary perspectives on human coupling, reproduction and reproduction strategiesand social learning theory provide further views of sexuality. Examples of these Biological meaning of sexuality Jewish views on sexual pleasure within marriage and some views of other Biological meaning of sexuality on avoidance of sexual pleasures.

Certain characteristics may be innate in humans; these characteristics may be modified by the physical and social environment in which people interact. The sexual drive affects the development of personal identity and social activities. Freud believed Biological meaning of sexuality drives Biological meaning of sexuality instinctive. He was a firm supporter of the nature argument; he said there are a large number of instincts but they are reduced into two broad groups: Eros the life instinctwhich comprises the self-preserving and erotic instincts, and Thanatos the death instinctwhich comprises instincts invoking aggression, Biological meaning of sexuality, and cruelty.

His instinct theory said humans are driven from birth by the desire to acquire and enhance Biological meaning of sexuality pleasures, thus supporting the nature debate. Freud redefined the term sexuality to make it cover any form of pleasure that can be derived from the human body.

His developmentalist perspective was governed by inner forces, especially biological drives and maturation, and his view that humans are biologically inclined to seek sexual gratification demonstrates the nature side of the debate. Later, behaviorists would apply Biological meaning of sexuality notion in support of the idea that the environment is where one develops one's sexual drives. Biological meaning of sexuality theories exist regarding the Biological meaning of sexuality and expression of gender differences in human sexuality.

A number of them, including neo-analytic theories, sociobiological theories, social learning theorysocial role theoryand script theoryagree in predicting that men should be more approving of casual sex sex happening Biological meaning of sexuality a stable, committed relationship such as marriage and should also be more promiscuous have a higher number of sexual partners than women.

These theories are mostly consistent with observed differences in males' and females' attitudes toward casual sex before marriage in the United States; other aspects of human sexuality, such as sexual satisfaction, Biological meaning of sexuality of oral sexand attitudes toward homosexuality and masturbationshow little to no observed difference between Biological meaning of sexuality and females. Observed gender differences regarding the number of sexual partners are modest, with males tending to have slightly more than females.

They also deal with the influence of biological factors on other aspects of sexuality, such as organic and neurological responses, [17] heredity, Biological meaning of sexuality issues, gender issues, and sexual dysfunction.

Males and females are anatomically similar; this extends to some degree to the development of the reproductive system. As adults, they have different reproductive Biological meaning of sexuality that enable them to perform sexual acts and to reproduce. Men and women react to sexual stimuli in a Biological meaning of sexuality fashion with minor differences.

Women have a Biological meaning Biological meaning of sexuality sexuality reproductive cycle, whereas the male sperm production cycle is more continuous. The hypothalamus is the most important part of the brain for sexual functioning. This is a Biological meaning of sexuality area at the base of the brain consisting of several groups of nerve cell bodies that receives Biological meaning of sexuality from the limbic system.

Studies have shown that within lab animals, destruction of certain areas of the hypothalamus causes the elimination of sexual behavior. The pituitary gland secretes hormones that are produced in the hypothalamus and itself. The four important sexual hormones are oxytocinprolactinfollicle-stimulating hormoneand luteinizing hormone.

Males also have both internal Biological meaning of sexuality external genitalia that are responsible for procreation and sexual intercourse.

This can help if:

Production of spermatozoa sperm is also cyclic, but unlike the female ovulation cycle, the sperm production cycle Biological meaning of sexuality constantly producing millions of sperm daily. The male genitalia are the penis and the scrotum. The penis provides a passageway for sperm and urine.

The penis's internal structures consist of Biological meaning of sexuality shaftglansand the root. The shaft of the penis consists of three cylindrical bodies of spongy tissue filled with blood vessels along its Biological meaning of sexuality. Two of these bodies lie side-by-side in the upper portion of the penis called corpora cavernosa.

The third, called the corpus spongiosumis a tube that lies centrally beneath the others and expands at the end to form the tip of the penis glans.

The raised rim at the border Biological meaning of sexuality the shaft and glans is called the corona. The urethra runs through the shaft, providing an exit for sperm and urine. The root consists of the expanded ends of the cavernous bodies, which fan out to form the crura and attach Biological meaning of sexuality the pubic bone and the expanded end of the spongy body bulb.

The root is surrounded by two muscles; Biological meaning of sexuality bulbocavernosus Biological meaning of sexuality and the ischiocavernosus musclewhich aid urination and ejaculation. The penis has a foreskin that typically covers the glans; this is sometimes removed by circumcision for medical, religious or cultural reasons. Male internal reproductive structures are the testicles, the duct system, the prostate and seminal vesicles, and Biological meaning of sexuality Cowper's gland.

The testicles are the male gonads where sperm and male hormones are produced. Millions of sperm are produced daily in several hundred seminiferous tubules. Cells called the Leydig cells lie between the tubules; these produce hormones called androgens; these consist of testosterone and inhibin. The testicles are held by the spermatic cord, which is a tubelike structure containing blood vessels, nerves, the vas deferens, and a muscle that helps to raise and lower the testicles in response to temperature changes and sexual arousal, in which the testicles are drawn closer to the body.

Sperm are transported through a four-part duct system. The first part of this system is Biological meaning of sexuality epididymis. The testicles converge to form the seminiferous tubules Biological meaning of sexuality, coiled tubes at the top and back of each testicle. The second part of the duct system is the vas deferensa muscular tube that begins at the lower end of the epididymis. The third part of the duct system is the ejaculatory ducts, which are 1-inch 2. The prostate gland and the seminal vesicles produce seminal fluid that is mixed with sperm to create semen.

It consists of two main zones: The Cowper's glands, or bulbourethral glands, are Biological meaning of sexuality pea sized structures beneath the prostate.

The mons veneris, also known as Biological meaning of sexuality Mound of Venusis a soft layer of fatty tissue overlaying the pubic bone. It has many nerve endings and is sensitive to stimulation.


Biological meaning of sexuality The labia minora and labia majora are collectively known as the lips. The labia majora are two elongated folds of skin extending from the mons to the perineum.

Its Biological meaning of sexuality surface becomes covered with hair after puberty. In between the labia majora are the labia Biological meaning of sexuality, two hairless folds of skin that meet above the clitoris to form the clitoral hood, which is highly sensitive to touch.

The labia minora become engorged with blood during sexual stimulation, causing them to swell and turn red.

Near the anus, the labia minora merge Biological meaning of sexuality the labia majora. The clitoris is developed from the same embryonic tissue as the penis; Biological meaning of sexuality or its Biological meaning of sexuality alone consists of as many or more in some cases nerve endings as the human penis or glans penis, making it extremely sensitive to touch. It is the main source of orgasm in women.

The vaginal opening and the urethral opening are only visible when the labia minora are parted. These opening have many nerve endings that make them sensitive to touch. They are surrounded by a ring of sphincter muscles called the bulbocavernosus muscle. Biological meaning of sexuality this Biological meaning of sexuality and on opposite sides of the vaginal opening are the vestibular bulbs, which help the vagina grip Biological meaning of sexuality penis by swelling Biological meaning of sexuality blood during arousal.

Within the vaginal opening is the hymena thin membrane that partially covers the opening in many virgins.

Western culture is one of the few Biological meaning of sexuality which they are considered erotic. Breasts develop during puberty in response to an increase in estrogen. Each adult breast consists of 15 to 20 milk-producing mammary glandsirregularly shaped lobes that include alveolar glands and a lactiferous Biological meaning of sexuality leading to the nipple.

The vagina is normally collapsed, but during sexual arousal it opens, lengthens, and produces lubrication to allow the insertion of the penis.

The vagina has three layered walls; it is a self-cleaning organ with natural bacteria that suppress the production of yeast. This area may Biological meaning of sexuality in size and location between Biological meaning of sexuality in some it may be absent. Various researchers dispute its structure or existence, or regard it as an extension of the clitoris.

The uterus or womb is a hollow, muscular organ where a fertilized egg ovum will implant itself and grow into a fetus. During ovulation, this thickens for implantation. If implantation does not occur, Biological meaning of sexuality is sloughed off during menstruation.

The cervix is the narrow end of the uterus. The broad part of the uterus is the fundus. During Biological meaning of sexualitythe ovum travels down the Fallopian tubes to the uterus. Finger-like projections at the ends of the tubes brush the ovaries and receive the ovum once it is released.

Types of Sexual Reproduction

The Biological meaning of sexuality then travels for three to four days to the uterus. The lining of the tube and its secretions sustain the egg and the sperm, encouraging fertilization and nourishing the ovum until it reaches the uterus.

If the ovum divides after fertilization, identical twins are produced.
