Definition

noun, plural: apocrine glands

A type of exocrine gland in which the secretory products are released together with some portions of the secreting cells, i.e. portions of the plasma membrane budding off the cell


Supplement

The secretory products of an apocrine gland are released from the cell through a portion of the plasma membrane that encases them and eventually pinches off. Thus, the apocrine gland differs from the other exocrine glands (i.e. holocrine andmerocrine glands) by including some parts of the cell with the secretory products. Examples of apocrine gland include the mammary glands and the axillary sweat glands.


Word origin: apo (off) + krinein (to separate)
