Question

multiple choice question
tongue papillae, which are visible to the naked eye, have ______ along their walls.

○ microvilli
○ taste buds
○ mechanoreceptors
○ merkel cells

Explanation:

Tongue papillae are structures on the tongue. Taste buds are located along the walls of the visible - to - the - naked - eye tongue papillae and are responsible for the sense of taste. Microvilli are on cells like intestinal cells, not on tongue papillae walls. Mechanoreceptors detect mechanical stimuli and are not the main feature along tongue papillae walls. Merkel cells are related to touch sensation and not found along tongue papillae walls in this context.

Answer:

B. taste buds
