Gland

Structure that makes and secretes a product; Arise from epithelial tissue that grow inward into underlying connective tissue rather than remaining on the surface

Glands release their product by 2 mechanisms: exocrine glands and endocrine glands

2
New cards

Exocrine Glands

Release their secretions to the apical surface of the epithelium through a duct lined with epithelial cells

Have local actions only

Vary in complexity from single-celled glands to large glands with branching ducts and many secretory units

ex. Unicellular Glands include the Goblet Cell, which is found in the epithelial lining of the digestive and respiratory tracts and secretes mucus

New cards

Endocrine Glands

Secrete hormones directly into the blood

Lack ducts

Reach distant target cells

4
New cards

Multicellular Glands

classified by the structure of their ducts and the shape of their secretory cell clusters:

Duct structure

-Simple Glands- ducts do not have branch

-Compound gland- ducts do have branches

Shape of Secretory Cell Clusters

-Tubular- long or straight or coiled

-Acinar- Spherical

-Tubuloacinar- both tubular and acinar portions

New cards

3 types of exocrine secretion

merocrine, holocrine, apocrine

6
New cards

Merocrine

Glands package products into secretory vesicles for release by exocytosis

most glands secrete this way

Salivary and sweat glands

New cards

Holocrine

Secretory cells accumulate product in the cytosol, which is released when the cell ruptures and dies

Sebaceous (oil) glands of the skin

New cards

Apocrine

Portions of cytoplasm are pinched off with the secreted product

Lipid droplets in milk from mammary glands
