Which cell type is primarily responsible for mucus production in mucous membranes?

• A. Fibroblast
• B. Goblet cell
• C. Neuron
• D. Osteoblast

Answer: (B)

Goblet cells are specialized mucus-secreting epithelial cells embedded in the lining of mucous membranes. They produce mucins that hydrate to form mucus, which lubricates surfaces and traps pathogens in the respiratory and digestive tracts. The other cell types have different roles: fibroblasts are in connective tissue and make extracellular matrix, neurons transmit nerve signals, and osteoblasts build bone, none of which produce mucus.
