Solution

The correct option is B False
Specific chemicals in solution pass into the taste bud through the taste pore to come in contact with the protein receptor sites on the microvilli of the gustatory receptor cells. The latter set up nerve impulses in the sensory nerve fibres. The nerve fibres transmit the impulses to the taste centre in the brain where the sensation of taste arises. The facial nerve serves the anterior two-thirds of the tongue, the glossopharyngeal nerve serves the posterior one-third of the tongue. Sweet taste is on the tip of the tongue, salt taste is on the sides and tips of the tongue, sour taste is on the sides of the tongue and bitter taste is on the base of the tongue. Therefore, tasting is possible with the help of taste buds.
So, the correct answer is 'False'.
