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.

Description
This quiz covers the functional classification of exocrine glands, focusing on the three main types: merocrine, apocrine, and holocrine glands. Each gland type's secretion process is outlined, highlighting the mechanisms involved in their function and release. Test your understanding of these critical concepts in glandular biology.
