Apocrine

Apocrine is a term used to classify exocrine glands in the study of histology. Cells which are classified as apocrine bud their secretions off through the plasma membrane producing membrane-bound vesicles in the lumen. The apical portion of the secretory cell of the gland pinches off and enters the lumen. It loses part of its cytoplasm in their secretions. Apocrine glands are found around armpits & the nipples and the groin regions of the body. Apocrine is functional during hormonal stress or puberty.
