Question

An apocrine type of secretion is characteristic of

• A. oviductal epithelium
• B. granulosa cells of ovarian follicles
• C. alveoli of the mammary gland
• D. Leydig cells of the testis

Answer 1

The correct option is C alveoli of the mammary gland

• Cells which are classified as apocrine bud their secretions off through the plasma membrane producing extracellular membrane-bound vesicles.
• 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 primarily in the breast of lactating mammals. Hence, An apocrine type of secretion is characteristic of alveoli of the mammary gland.

So, the correct answer is 'alveoli of the mammary gland'.
