Questions and Answers

What are the functional classifications of exocrine glands based on?

How their secretions are released.

What describes merocrine glands?

  • Secretions are stored in the cytosol.
  • Cells rupture and release the secretion.
  • Secretions accumulate at the apical surface and pinch off.
  • Secretions are synthesized on ribosomes attached to rough ER. (correct)
  • What describes apocrine glands?

  • Secretions are synthesized on ribosomes attached to rough ER.
  • Cells rupture and release the secretion.
  • Secretions are stored in the cytosol.
  • Secretions accumulate at the apical surface and pinch off. (correct)
  • What describes holocrine glands?

    Study Notes

    Functional Classification of Exocrine Glands

    • Functional classification of exocrine glands is based on how their secretions are released from the cells.

    Merocrine Glands

    • Secrete products via exocytosis.
    • Secretions are synthesized on ribosomes that are attached to the rough endoplasmic reticulum (ER).
    • Processed, sorted, and packaged by the Golgi complex before being released.

    Apocrine Glands

    • Secrete by accumulating products at the apical surface.
    • The apical portion of the secreting cell pinches off through exocytosis to release the secretion.

    Holocrine Glands

    • Accumulate secretory products within the cytosol.
    • As the cell matures, it ruptures, releasing its contents as the secretory product.
