Describe the structure and location of various taste buds.

Answer»

Structure of taste buds: There are four primary tastes-sweet, salty, sour and bitter. The taste receptors are called taste buds. Each taste bud opens on the tongue surface through a taste pore. Each taste buds contains 60-65 spindle-shaped cells, out of which 5-15 are taste receptor cells and others supporting cells. The taste receptor cells produce protoplasmic outgrowths called taste hair. The taste hair project through taste pore and receive the stimulus of taste.
