Apocrine secretion

Japanese: アポクリン分泌 - あぽくりんぶんぴつ

…A type of gland that performs secretory function. In glandular cells, the way secretions are released outside the cell body includes total secretion, exocrine secretion, and exocrine secretion. Exocrine secretion is also called apocrine secretion, and glands formed from a group of cells that cause apocrine secretion are called apocrine glands. Exocrine secretion is when large cytoplasmic projections form on the cell surface, their bases become constricted and cut off, and secretions are produced. …

…The eyelid margin is also a similar transitional area, but this area has thick, long hairs called eyelashes, and the sebaceous glands (tarsal or meibomian glands) that open into the roots of these hairs are powerful. The major sweat glands are only found in limited areas of the skin, such as the armpits, external ear canal, and vulva, but their secretions have a unique smell and taste (the secretion pattern of the major sweat glands is apocrine secretion or exudative secretion, in which small protruding parts of the glandular cells are torn off and discharged). In humans, the earwax gland is the major sweat gland in the external ear canal skin, and the eyelash gland (molar gland) is the major sweat gland in the eyelid margin skin. …

…分泌機能をいとなむ腺の一種。腺細胞において，分泌物が細胞体外へ放出される方法には，全分泌，離出分泌，開口分泌などがあるが，離出分泌はアポクリン分泌apocrine secretionともいい，アポクリン分泌を起こす細胞群からできた腺をアポクリン腺という。離出分泌とは，細胞表面に大きい細胞質の突起ができて，その根元がくびれて離断し，分泌物になるものである。…

…眼瞼（がんけん）縁も同様な移行部の一つであるが，この部位には睫毛（しようもう）(まつげ)と称される太くて長い毛があり，その毛根に開口する皮脂腺(瞼板腺あるいはマイボーム腺)が強大である。大汗腺は腋窩（えきか），外耳道，外陰部などの限られた領域の皮膚にしか存在しないが，その分泌物には独特のにおいや味がある(大汗腺の分泌様式はアポクリン分泌または離出分泌で腺細胞の小突出部分がちぎれて排出される)。ヒトの耳垢（じこう）腺は外耳道皮膚，睫毛腺(モル腺)は眼瞼縁皮膚における大汗腺にほかならない。…
