Preputial Glands
Preputial glands are exocrine glands in the prepuce in front of the penis. They occur in many mammals, including canids, mice, ferrets, rhinoceroses, and even-toed ungulates and produce pheromones. The preputial glands of female animals are sometimes called clitoral glands. Male canids scent-mark their territories with urine and preputial gland secretions. The preputial glands of male musk deer produce strong-smelling deer musk which is of economic importance, as it is used in perfumes. Human homologues There is debate about whether humans have functional homologues to preputial glands. Preputial glands were first noted by Edward Tyson and in 1694, fully described by William Cowper who named them Tyson's glands after Tyson. They are modified sebaceous glands located around the corona and inner surface of the prepuce of the human penis In Human body, human anatomy, the penis (; : penises or penes; from the Latin ''pēnis'', initially 'tail') is an external sex orga ...

Exocrine Gland
Exocrine glands are glands that secrete substances onto an epithelial surface by way of a duct. Examples of exocrine glands include sweat, salivary, mammary, ceruminous, lacrimal, sebaceous, prostate and mucous. Exocrine glands are one of two types of glands in the human body, the other being endocrine glands, which secrete their products directly into the bloodstream. The liver and pancreas are both exocrine and endocrine glands; they are exocrine glands because they secrete products—bile and pancreatic juice—into the gastrointestinal tract through a series of ducts, and endocrine because they secrete other substances directly into the bloodstream. Exocrine sweat glands are part of the integumentary system; they have eccrine and apocrine types. Classification Structure Exocrine glands contain a glandular portion and a duct portion, the structures of which can be used to classify the gland. * The duct portion may be branched (called compound) or unbranched (called sim ...

Edward Tyson
Edward Tyson (20 January 1651 – 1 August 1708) was an English scientist and physician. He is commonly regarded as the founder of modern comparative anatomy, which compares the anatomy between species. Biography Tyson was born the son of Edward Tyson at Clevedon, in Somerset. He became a BA from Oxford on 8 February 1670, an MA from Oxford on 4 November 1673, and an MD from Cambridge in 1678. He was admitted to the College of Physicians on 30 September 1680 and as a Fellow in April 1683. In 1684 he was appointed physician and governor to the Bethlem Hospital in London (the first mental hospital in Britain and the second in Europe). He is credited with changing the hospital from a zoo of sorts to a place intended to assist its inmates. He was elected a Fellow of the Royal Society in November 1679. He is buried at St Dionis Backchurch. Anatomical research In 1680, Tyson studied a porpoise and established that it is a mammal. He noted that the convoluted structures of the brains ...

Pearly Penile Papules
Pearly penile papules (PPP; also known as hirsutoid papillomas or as , Latin for 'papillae of the corona of the glans') are benign, small bumps or spots on the human penis. They vary in size from 0.5-1 mm, are pearly or flesh-colored, smooth and dome-topped or filiform, and appear in one or, several rows around the corona, the ridge of the head of the penis and sometimes on the penile shaft. They are painless, non-cancerous and not harmful. The medical condition of having such papules is called hirsutoid papillomatosis or (Latin for 'papillary hirsutism of the corona of the glans'). Cause and mechanism PPPs are a type of angiofibroma. Their function is not well-understood. They are usually considered as vestigial remnants of penile spines, sensitive features found in the same location in other primates. They do not spread and often spontaneously regress. Along with Fordyce glands, PPPs secrete oils to keep the skin of the head of the penis in good condition. Smeg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Journal Of Urology

Smegma
Smegma (from Ancient Greek ) is shed skin cells, skin oils, and moisture that occurs in male and female mammalian genitalia. In males, smegma collects under the foreskin; in females, it collects around the clitoris and in the folds of the labia minora. Females The accumulation of sebum combined with dead skin cells forms smegma. ''Smegma clitoridis'' is defined as the secretion of the apocrine (sweat) and sebaceous (sebum) glands of the clitoris in combination with desquamating epithelial cells. Glands that are located around the clitoris, the labia minora, and the labia majora secrete sebum. If smegma is not removed frequently it can lead to clitoral adhesion which can make clitoral stimulation (such as masturbation) painful (clitorodynia). Males In males, smegma helps keep the glans moist and facilitates sexual intercourse by acting as a lubricant. Smegma was originally thought to be produced by sebaceous glands near the frenulum called Tyson's glands; however, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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] |
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 ...

Corona Of Glans Penis
The corona of glans penis (or, directly from the Latin, the corona glandis penis) or penis crown refers to the rounded projecting border or flare that forms at the base of the glans in human males. The corona overhangs a mucosal surface, known as the neck of the penis, which separates the shaft and the glans. The deep retro-glandular coronal sulcus forms between the corona and the neck of the penis. The two sides of the corona merge on the ventral midline forming the septum glandis. The circumference of the corona is richly innervated and is described as a highly erogenous area of the glans. Structure Development During the embryonic development of the male fetus, a thickening on the epidermis appears around the base of the developing glans. The thickening separates from the glans creating the preputial fold and the preputial lamina on its ventral surface. The lamina expands outwards over the epithelium of the glans and also backwards forming an ingrowing fold at the base ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
