Q.The sense of taste is considered to be the most pleasurable of all senses.
Describe the structure of the receptor involved with a diagram.

Step 1. Most taste buds sit on the tongue's papillae (small projections such as fungiform and vallate papillae that give the tongue its rough texture), with a few also on the soft palate, cheeks, pharynx and epiglottis.

Step 2. Each taste bud is flask-shaped and built of 50–100 epithelial cells of two types: gustatory epithelial cells (the taste-sensing cells) and basal epithelial cells (repairing/regenerating cells that continually replace worn-out gustatory cells, roughly every 7–10 days).

Step 3. Each gustatory cell projects long microvilli called gustatory hairs from its tip; these are the sensitive part of the cell and extend through a taste pore to the epithelial surface, where they are bathed in saliva carrying dissolved food chemicals. …
