eccrine secretion

Japanese: eccrine secretion（英語表記）eccrinesecretion

…A type of gland that performs secretory functions. When observed under an optical microscope, the secretory method in which the secretion does not damage the cell body has been collectively called leakage secretion (eccrine secretion). However, observation under an electron microscope has led to the classification of leakage secretion into exocytosis and diacrine secretion. …

From [Gland]

...It is seen in the apocrine sweat glands in the armpits, glands in the ear canal, and mammary glands. (3) Eccrine secretion Under optical microscopy, the secretion that comes out without damaging the cell body has been collectively called "eccrine secretion," but under electron microscopy, it is divided into the following two types. (a) Exocytosis In this type, secretory granules covered with a limiting membrane approach the cell surface, then the limiting membrane and the cell membrane fuse, the fusion point opens, and only the granule contents come out. ...

…分泌機能をいとなむ腺の一種。光学顕微鏡によって観察した場合に分泌物が細胞体を傷つけずに外へ出る分泌方式を総称して漏出分泌(エクリン分泌eccrine secretion)と呼んできた。しかし，電子顕微鏡での観察によって，漏出分泌は開口分泌exocytosisと透出分泌diacrine secretionに分けられるようになった。…
