Which of the following statements is correct about receptors?
(a) Gustatory receptors detect taste while olfactory receptors detect smell
(b) Both gustatory and olfactory receptors detect smell
(c) Auditory receptors detect smell and olfactory receptors detect taste
(d) Olfactory receptors detect taste and gustatory receptors smell
Explanation:
A receptor is a cell or group of cells that help in detecting external stimuli. Gustatory receptors are taste receptors present on the papillae of the tongue. Olfactory receptors help in detecting smell and are present on the roof of the nasal cavity. Both the receptors send the information to the brain to interpret the stimulus and generate an appropriate response. Auditory receptors in the ears help in detecting voices. Hence, (a) is the correct option.
