Concept explainers
Receptor cells for taste are located
a. only on the tongue.
b. on the tongue, oral cavity, and pharynx.
c. in the oral cavity except the tongue.
d. on the tongue and nasal passages.
Introduction:Mechanoreceptor can be defined as a cell or sense organ which responds to the mechanical stimuli (such as sound or touch). Sense organs are those organs which respond to the exterior stimuli by the transmission of impulses to the sensory nervous system.
Answer to Problem 1PL
Correct answer:
The correct answer is the option (b). On the tongue, oral cavity, and pharynx.
Explanation of Solution
Explanation/justification for the correct answer:
Option (b). On the tongue, oral cavity, and pharynx. Taste receptors are the extended epithelial cells located all over the pharynx, epiglottis, tonsils, oral cavity, soft and hard palates. But these are present in abundance on the tongue. Hence, the option (b) is correct.
Explanation for the correct answer:
Option (a) Only on the tongue. Taste receptors are present in abundance on the tongue.
Hence, the option (a) is incorrect.
Option (c) In the oral cavity except the tongue. Taste receptors are the extended epithelial cells on the oral cavity. Hence, the option (c) is incorrect.
Option (d) On the tongue and nasal passages. Taste receptors are not present in the nasal passage. Hence, the option (d) is incorrect.
Taste receptors are the extended epithelial cells located all over the pharynx, epiglottis, tonsils, oral cavity, soft palates, and hard palates and on the tongue. Hence, the option (b) is correct.
