Question

mammary glands are modified sweat glands which use both merocrine and ______ cells to produce breast milk.

○ apocrine
○ endocrine
○ eccrine
○ epicrine
○ holocrine

Explanation:

Mammary glands, as modified sweat glands, use merocrine (eccrine - like in some aspects) and apocrine secretion mechanisms. Apocrine cells are involved in milk production along with merocrine. Endocrine is about hormone secretion into blood, eccrine is typical sweat glands (not for milk with merocrine here), epicrine is not related to mammary gland secretion, and holocrine is cell - bursting secretion (not for milk). So the correct term is apocrine.

Answer:

A. apocrine
