Clitoris - Wikipedia. The clitoris ( ( listen) or  ( listen)) is a female sex organ present in mammals, ostriches and a limited number of other animals.

In humans, the visible button- like portion is near the front junction of the labia minora (inner lips), above the opening of the urethra. Unlike the penis, the male homologue (equivalent) to the clitoris, it usually does not contain the distal portion (or opening) of the urethra and is therefore not used for urination. While few animals urinate through the clitoris, the spotted hyena, which has an especially well- developed clitoris, urinates, mates and gives birth via the organ. Some other mammals, such as lemurs and spider monkeys, also have a well- developed clitoris.[1]The clitoris is the human female's most sensitive erogenous zone and generally the primary anatomical source of human female sexual pleasure.[2] In humans and other mammals, it develops from an outgrowth in the embryo called the genital tubercle.

Initially undifferentiated, the tubercle develops into either a penis or a clitoris, depending on the presence or absence of the protein tdf, which is codified by a single gene on the Y chromosome. The clitoris is a complex structure, and its size and sensitivity can vary.

The glans (head) of the human clitoris is roughly the size and shape of a pea, and is estimated to have more than 8,0. Extensive sociological, sexological and medical debate have focused on the clitoris, primarily concerning anatomical accuracy, orgasmic factors and their physiological explanation for the G- spot, and whether the clitoris is vestigial, an adaptation, or serves a reproductive function.[4] Social perceptions of the clitoris range from the significance of its role in female sexual pleasure, assumptions about its true size and depth, and varying beliefs regarding genital modification such as clitoris enlargement, clitoris piercing and clitoridectomy.[5] Genital modification may be for aesthetic, medical or cultural reasons.[5]Knowledge of the clitoris is significantly impacted by cultural perceptions of the organ. Studies suggest that knowledge of its existence and anatomy is scant in comparison with that of other sexual organs, and that more education about it could help alleviate social stigmas associated with the female body and female sexual pleasure; for example, that the clitoris and vulva in general are visually unappealing, that female masturbation is taboo, or that men should be expected to master and control women's orgasms.[6]Etymology. The Oxford English Dictionary states that the word clitoris likely has its origin in the Ancient Greekκλειτορίς, kleitoris, perhaps derived from the verb κλείειν, kleiein, "to shut".[7]Clitoris is also Greek for the word key, "indicating that the ancient anatomists considered it the key" to female sexuality.[8][9] In addition to key, the Online Etymology Dictionary suggests other Greek candidates for the word's etymology include a noun meaning "latch" or "hook"; a verb meaning "to touch or titillate lasciviously", "to tickle" (one German synonym for the clitoris is der Kitzler, "the tickler"), although this verb is more likely derived from "clitoris"; and a word meaning "side of a hill", from the same root as "climax".[1. The Oxford English Dictionary also states that the shortened form "clit", the first occurrence of which was noted in the United States, has been used in print since 1.

The plural forms are clitorises in English and clitorides in Latin. The Latin genitive is clitoridis, as in "glans clitoridis". In medical and sexological literature, the clitoris is sometimes referred to as "the female penis" or pseudo- penis,[1.

Structure. Development. In mammals, sexual differentiation is determined by the sperm that carries either an X or a Y (male) chromosome.[1. The Y chromosome contains a sex- determining gene (SRY) that encodes a transcription factor for the protein tdf (testis determining factor) and triggers the creation of testosterone and Anti- Müllerian hormone for the embryo's development into a male.[1. This differentiation begins about eight or nine weeks after conception.[1. Some sources state that it continues until the twelfth week,[1. The clitoris develops from a phallic outgrowth in the embryo called the genital tubercle. Initially undifferentiated, the tubercle develops into either a clitoris or penis during development of the reproductive system depending on exposure to androgens (primarily male hormones).

The clitoris forms from the same tissues that become the glans and upper shaft of the penis, and this shared embryonic origin makes these two organs homologous (different versions of the same structure).[1. If exposed to testosterone, the genital tubercle elongates to form the penis.

By fusion of the urogenital folds – elongated spindle- shaped structures that contribute to the formation of the urethral groove on the belly aspect of the genital tubercle – the urogenital sinus closes completely and forms the spongy urethra, and the labioscrotal swellings unite to form the scrotum.[1. In the absence of testosterone, the genital tubercle allows for formation of the clitoris; the initially rapid growth of the phallus gradually slows and the clitoris is formed. The urogenital sinus persists as the vestibule of the vagina, the two urogenital folds form the labia minora, and the labioscrotal swellings enlarge to form the labia majora, completing the female genitalia.[1. A rare condition that can develop from higher than average androgen exposure is clitoromegaly.[1.

General structure and histological evaluation. Clitoris; deep dissection. The clitoris is a complex structure, containing external and internal components.

It consists of the glans (including the frenulum of clitoris, which is a frenulum on the under- surface of the glans and is created by the two medial parts of the labia minora), the clitoral body (which is composed of two erectile bodies known as the corpora cavernosa), two clitoral crura, the clitoral hood (formed by the labia minora) and the vestibular or clitoral bulbs.[2. The clitoral body is commonly referred to as the shaft (or internal shaft), while the length of the clitoris between the glans and the body may also be referred to as the shaft (or external shaft) because, like the shaft as a whole, it supports the glans, and its shape can be seen and felt through the clitoral hood.[2.

Research indicates that clitoral tissue extends into the vagina's anterior wall.[2. They added that Baskin and colleagues examined the clitoris's masculinization after dissection and, using imaging software after Masson chrome staining, put the serial dissected specimens together; this revealed that the nerves of the clitoris surround the whole clitoral body (corpus).[2. The clitoris, vestibular bulbs, labia minora, and urethra involve two histologically distinct types of vascular tissue (tissue related to blood vessels), the first of which is trabeculated, erectile tissue. The trabeculated tissue has a spongy appearance; along with blood, it fills the large, dilated vascular spaces of the clitoris and the bulbs.

Beneath the epithelium of the vascular areas is smooth muscle.[2. It may also be that the urethral lumen (the inner open space or cavity of the urethra), which is surrounded by spongy tissue, has tissue that "is grossly distinct from the vascular tissue of the clitoris and bulbs, and on macroscopic observation, is paler than the dark tissue" of the clitoris and bulbs.[2.
