NEET Previous Year Question
Which of the following receptors are specifically responsible for maintenance of balance of body and posture?
Topic: NEET PYQ
Answer: D. Full step-by-step solution below.
- ABasilar membrane and otoliths
- BHair cells and organ of corti
- CTectorial membrane and macula
- DCrista ampullaris and macula
Correct answer: D
Solution
(d) (a) → Incorrect → Basilar membrane is involved in hearing, while otoliths help in balance. Both together are not the specific receptors.(b) → Incorrect → Hair cells are sensory cells, and the Organ of Corti is the receptor for hearing, not body balance.
(c) → Incorrect → Tectorial membrane is associated with hearing, whereas macula is a balance receptor.
(d) → Correct → Crista ampullaris (in semicircular canals) detects angular/rotational movements, and macula (in utricle and saccule) detects linear acceleration and static balance. Together, they maintain body balance and posture.
