Standing Still in an Elevator That Suddenly Lowers Will Stimulate

Question

Standing still in an elevator that suddenly lowers will stimulate receptors in the
A) basilar membrane.
B) spiral organ.
C) semicircular canals.
D) bony labyrinth.
E) utricle and saccule.

Accepted Answer

The utricle and saccule are part of the vestibular system in the inner ear that detect changes in linear acceleration and gravity. When the elevator suddenly lowers, the utricle and saccule will detect this movement and send signals to the brain. The other options listed are not directly involved in the detection of linear acceleration and gravity changes.
