Method of Secretion

Exocrine glands are named apocrine glands, holocrine glands, or merocrine glands based on how their products are excreted.

  • Apocrine glands - a portion of the plasma membrane buds off the cell, containing the excretion.
  • Holocrine glands - the entire cell disintegrates to excrete its substance, an example is sebaceous glands for skin and nose.
  • Merocrine glands or (eccrine glands) - cells excrete their substances by exocytosis an example is pancreatic acinar cells.
