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: -The most common unicellular exocrine glands are the goblet cells (mucus secreting cells) found in the epithelium of the trachea and the digestive tube.

Detailed explanation-3: -Goblet cells are found intercalated within the epithelia of the conjunctiva, respiratory epithelium, and gastrointestinal epithelium.

Detailed explanation-4: -The mucous membrane lining the trachea consists of pseudostratified ciliated columnar epithelium with numerous goblet cells. The mucous produced by the goblet cells traps inhaled particles and the cilia move the mucous and particle to the larynx, from which they enter the pharynx and are swallowed or spit out.
