Glans
The glans (, : glandes ; from the Latin word for "acorn") is a vascular structure located at the tip of the penis in male mammals or a homologous genital structure of the clitoris in female mammals. Structure The exterior structure of the glans consists of mucous membrane, which is usually covered by foreskin or clitoral hood in naturally developed genitalia. This covering, called the prepuce, is normally retractable in adulthood unless removed by circumcision. The glans naturally joins with the frenulum of the penis or clitoris, as well as the inner labia in women, and the foreskin in men. In non-technical or sexual discussions, often the word "clitoris" refers to the external glans alone, excluding the clitoral hood, frenulum, and internal body of the clitoris. Similarly, phrases "tip" or "head" of the penis refers to the glans alone. Sex differences in humans In males, the glans is known as the glans penis, while in females the glans is known as the clitoral glans. ...

Glans Penis
In male human anatomy, the glans penis or penile glans, commonly referred to as the glans, (; from Latin ''glans'' meaning "acorn") is the bulbous structure at the Anatomical terms of location#Proximal and distal, distal end of the human penis that is the human male's most sensitive erogenous zone and primary anatomical source of Human sexuality, sexual pleasure. The glans penis is present in the male reproductive system, reproductive organs of humans and most other mammals where it may appear smooth, spiny, elongated or divided. It is externally lined with Mucosa, mucosal tissue, which creates a smooth texture and glossy appearance. In humans, the glans is located over the distal ends of the Corpus cavernosum penis, corpora cavernosa and is a continuation of the Corpus spongiosum (penis), corpus spongiosum of the penis. At the summit appears the urinary meatus and at the base forms the Corona of glans penis, corona glandis. An elastic band of tissue, known as the Penile frenulum ...

Foreskin
In male Human body, human anatomy, the foreskin, also known as the prepuce (), is the double-layered fold of Human skin, skin, Mucous membrane, mucosal and Muscle tissue, muscular tissue at the distal end of the human penis that covers the glans penis, glans and the urinary meatus. The foreskin is attached to the glans by an elastic band of tissue, known as the Frenulum of prepuce of penis, frenulum. The outer skin of the foreskin meets with the inner preputial mucosa at the area of the mucocutaneous junction. The foreskin is mobile, fairly stretchable and sustains the glans in a moist environment. Except for humans, a similar structure known as a penile sheath appears in the male sexual organs of all primates and the vast majority of mammals. In humans, foreskin length varies widely and coverage of the glans in a flaccid and erect state can also vary. The foreskin is fused to the glans at birth and is generally not wiktionary:retractable, retractable in infancy and early childho ...

Clitoris
In amniotes, the clitoris ( or ; : clitorises or clitorides) is a female sex organ. In humans, it is the vulva's most erogenous zone, erogenous area and generally the primary anatomical source of female Human sexuality, sexual pleasure. The clitoris is a complex structure, and its size and sensitivity can vary. The visible portion, the glans, of the clitoris is typically roughly the size and shape of a pea and is estimated to have at least 8,000 Nerve, nerve endings. * * Peters, B; Uloko, M; Isabey, PHow many Nerve Fibers Innervate the Human Clitoris?

Human Penis
In Human body, human anatomy, the penis (; : penises or penes; from the Latin ''pēnis'', initially 'tail') is an external sex organ (intromittent organ) through which males urination, urinate and ejaculation, ejaculate, as Penis, on other animals. Together with the testes and surrounding structures, the penis functions as part of the male reproductive system. The main parts of the penis are the Root of penis, root, Body of penis, body, the epithelium of the penis, including the shaft skin, and the foreskin covering the glans penis, glans. The body of the penis is made up of three columns of tissue (biology), tissue: two Corpus cavernosum penis, corpora cavernosa on the dorsal side and corpus spongiosum penis, corpus spongiosum between them on the ventral side. The Urethra#Male, urethra passes through the prostate gland, where it is joined by the ejaculatory ducts, and then through the penis. The urethra goes across the corpus spongiosum and ends at the tip of the glans as the o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clitoral Hood
In female humans and other mammals, the clitoral hood (also called preputium clitoridis, clitoral prepuce, and clitoral foreskin) is a fold of skin that surrounds and protects the glans of the clitoris; it also covers the external clitoral shaft, develops as part of the labia minora and is homologous with the foreskin (also called the ''prepuce'') in the male reproductive system. The clitoral hood is composed of mucocutaneous tissues; these tissues are between the mucous membrane and the skin, and they may have immunological importance because they may be a point of entry of mucosal vaccines. Development and variation The clitoral hood is formed during the fetal stage by the cellular lamella. The cellular lamella grows down on the dorsal side of the clitoris and is eventually fused with the clitoris. The clitoral hood varies in the size, shape, thickness, and other aesthetic aspects. Some women have large clitoral hoods that completely cover the clitoral glans. Some of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Homologues Of The Human Reproductive System
This list of related male and female reproductive organs shows how the male and female reproductive organs and the development of the reproductive system are related, sharing a common developmental path. This makes them biological homologues. These organs differentiate into the respective sex organs in males and females. List Internal organs External organs The external genitalia of both males and females have similar origins. They arise from the genital tubercle that forms anterior to the cloacal folds (proliferating mesenchymal cells around the cloacal membrane). The caudal aspect of the cloacal folds further subdivides into the posterior anal folds and the anterior urethral folds. Bilateral to the urethral fold, genital swellings become prominent. These structures are the future scrotum and labia majora in males and females, respectively. The genital tubercles of an eight-week-old embryo of either sex are identical. They both have a glans area, which will go on to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circumcision
Circumcision is a procedure that removes the foreskin from the human penis. In the most common form of the operation, the foreskin is extended with forceps, then a circumcision device may be placed, after which the foreskin is excised. Topical or locally injected anesthesia is generally used to reduce pain and physiologic stress. Circumcision is generally electively performed, most commonly done as a form of preventive healthcare, as a religious obligation, or as a cultural practice. It is also an option for cases of phimosis, other pathologies that do not resolve with other treatments, and chronic urinary tract infections (UTIs). The procedure is contraindicated in cases of certain genital structure abnormalities or poor general health. The procedure is associated with reduced rates of sexually transmitted infections and urinary tract infections. This includes reducing the incidence of cancer-causing forms of human papillomavirus (HPV) and reducing HIV transmi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penis
A penis (; : penises or penes) is a sex organ through which male and hermaphrodite animals expel semen during copulation (zoology), copulation, and through which male placental mammals and marsupials also Urination, urinate. The term ''penis'' applies to many intromittent organs of vertebrates and invertebrates, but not to all. As an example, the intromittent organ of most Cephalopoda is the hectocotylus, a specialized arm, and male spiders use their pedipalps. Even within the Vertebrata, there are morphological variants with specific terminology, such as Hemipenis, hemipenes. Etymology The word "penis" is taken from the Latin word for "Latin profanity#Synonyms and metaphors, tail". Some derive that from Proto-Indo-European language, Indo-European ''*pesnis'', and the Greek word πέος = "penis" from Indo-European ''*pesos''. Prior to the adoption of the Latin word in English, the penis was referred to as a "yard". The Oxford English Dictionary cites an example of the w ...

Urinary Meatus
The urinary meatus (, ; : meati or meatuses), also known as the external urethral orifice, is the opening of the penis or vulva where urine exits the urethra during urination. It is also where semen exits during male ejaculation, and other fluids during female ejaculation. The meatus has varying degrees of sensitivity to touch. In human males The male external urethral orifice is the external opening of the urethra, normally located at the tip of the glans penis, at its junction with the frenular delta. It presents as a vertical slit, and continues longitudinally along the front aspect of the glans, which facilitates micturition. In some cases, the opening may be more rounded. This can occur naturally or may also occur as a side effect of excessive skin removal during circumcision. The meatus is a sensitive part of the male reproductive system. In human females The female external urethral orifice is where urine exits the urethra during urination. It is located about behin ...

Genital Tubercle
A genital tubercle, phallic tubercle, or clitorophallic structure is a body of tissue present in the development of the reproductive system of amniotes. It forms in the ventral, caudal region of mammalian embryos of both sexes, and eventually develops into a primordial phallus. In the human fetus, the genital tubercle develops around week four of gestation, and by week nine, becomes recognizably either a clitoris or penis. This should not be confused with the sinus tubercle which is a proliferation of endoderm induced by paramesonephric ducts. Even after the phallus is developed (either a penile shaft or clitoral shaft), the term genital tubercle remains, but only as the terminal end of it, which develops into either the glans penis or the glans clitoridis. In the development of the male fetus, the two sides of the tubercle approach ventrally forming a hollow tube that encloses the male urethra. The two glans wings merge in the midline forming the septum glandis. In the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
