MICROANATOMY

Detailed explanation-1: -Goblet cells are unicellular intraepithelial mucin-secreting glands scattered within simple epithelia, such as cuboidal, columnar, and pseudostratified epithelia. Their name corresponds to their shape, as they resemble a goblet, with their narrow bases and wide apex.

Detailed explanation-2: -Goblet cells are simple columnar epithelial cells that secrete gel-forming mucins, like mucin 5AC. The goblet cells mainly use the merocrine method of secretion, secreting vesicles into a duct, but may use apocrine methods, budding off their secretions, when under stress.

Detailed explanation-3: -The mucous membrane lining the trachea consists of pseudostratified ciliated columnar epithelium with numerous goblet cells.
