bones and CT Flashcards
How do merocrine glands secrete? Are their secretory cells altered in any way?
Merocrine glands secrete via exocytosis, the cells are not altered at all.
How do holocrine glands secrete? Are their secretory cells altered in any way?
Holocrine cells accumulate their products within them until the cells rupture. You can say they ‘die’ for their cause
How do apocrine glands secrete? Are their secretory cells altered in any way?
Apocrine cells sit just beneath the surface and accumulate their products, they eventually ‘pinch off’ a part of the cell and repair them.
