52
Exocrine glands
Secretions released via a duct or tube; empties onto apical surface
Range from 1 cell (e.g., goblet cell) to multicellular
53
Endocrine glands
Ductless glands
Secrete hormones (by exocytosis)
Secretions released by directly into blood or fluids
54
Exocytosis
Where a gland packages up secretion into a membrane bound sac, walling it off from everything else.
Cell then uses energy to move it to the wall of the cell.
The sac then murges with the wall of the cell since its made out of the same material. The secretion is now outside of the cell.
55
Merocrine Secretion
Product released from secretory vesicles by exocytosis
Produced by majority of exocrine glands
Examples
- Sweat (merocrine and apocrine sweat glands) common in skin around the body; common on palms and soles
- Saliva (from salivary glands)
- Mucus in digestive and respiratory tracts
- Milk from mammary glands **also involves some apocrine secretion**
56
Apocrine secretion
Involves shedding some cytoplasm and secretory vesicles
Gland cell grows and repairs before more releases
Examples
- Observed in lipid droplet secretion in lactating mammary glands of many mammals
57
Holocrine secretion
Entire gland cell packed with secretory vesicles
Cell bursts
- Releases secretion
- Kills cell
Cells replaced by stem cells
Example
- Secretions of sebaceous glands (oil glands) *Produced by oily secretion (sebum) to coat skin and hair
58
Glycoproteins
Cell-adhesion molecules
Help cells stick to each other and to hold them in place in the matrix;
Bind membrane proteins to protoglycans and protein fibers in matrix
59

Cell then uses energy to move it to the wall of the cell.
The sac then murges with the wall of the cell since its made out of the same material. The secretion is now outside of the cell.
