• Basal pole

• Basolateral region

• Nuclei

• Secretory granules

Linings of GI tract, respiratory system are BOTH columnar epithelia that are derived from endoderm.

• True

• False

Epithelial tissues are:

• Vascular and innervated

• Vascular and lacks nerves

• Avascular and lacks nerves

• Avascular and innervated

Type III collagen is mostly found in _____.

• Basal lamina

• Reticular lamina

• Lamina propria

• Lamina lucida

Basal lamina is a dense sheet that acts as a scaffold for epithelia, it is non-cellular, and its components are secreted by the underlying fibroblast of the connective tissue.

• True

• False

Which of these isn't epithelium?

• Epimysium

One of these isn't a function of basement membranes

• Filtration and selection of filtered molecules

• Provide mechanical support to epithelial cells

• Mediate cell-cell interactions and communications

• Help with epithelium repair by secreting growth factors

• Selective migration of cells
