ANATOMY

Detailed explanation-1: -The given statement is true. Epithelial tissues can regenerate if apical layers are damaged. The epithelial tissues undergo rapid regeneration as the epithelial cells have the ability to rapidly divide and produce new cells and they continue to divide throughout life.

Detailed explanation-2: -The homeostatic replacement of cells varies substantially among different epithelia. The epithelium of the intestine completely self-renews within ∼5 days. By contrast, interfollicular epidermis takes ∼4 weeks to renew, whereas the lung epithelium can take as long as 6 months to be replaced.

Detailed explanation-3: -Answer and Explanation: The true statement is b) Cells in a pseudostratified columnar epithelium are all attached to the same basement membrane.

Detailed explanation-4: -• The epithelial cells aid in maintaining a stable tear film, and for secreting the epithelial basement membrane-critical in corneal healing. Corneal epithelial cells are constantly turned over as the outermost cells are shed into the tear film. The entire epithelium is turned over in approximately seven to 10 days.

Detailed explanation-5: -Answer and Explanation: Epithelial cells reproduce rapidly. In fact, they are one of the fastest reproducing cells found in the body.
