NEET BIOLOGY

Detailed explanation-1: -Goblet cells are modified epithelial cells that secrete mucus on the surface of mucous membranes of organs, particularly those of the lower digestive tract and airways. Histologically, they are mucous merocrine exocrine glands.

Detailed explanation-2: -Mucus is secreted by the goblet cells and typically contains several major components. One of these, the mucins, gives the mucus its gel-like properties.

Detailed explanation-3: -Goblet cells are specialized for the synthesis and secretion of mucus. They acquired their name for their typical goblet, cup-like, appearance formed by the mucin granulae that fill up the cytoplasm (Figure 1).

Detailed explanation-4: -Function. The main role of goblet cells is to secrete mucus in order to protect the mucous membranes where they are found. Goblet cells accomplish this by secreting mucins, large glycoproteins formed mostly by carbohydrates.
