Linear acceleration is sensed by the
A) cochlea.
B) otolith organs.
C) semicircular canals.
D) nociceptors.

Question

Quizplus · Accepted Answer

Linear acceleration, such as changes in speed or direction, is detected by the otolith organs in the inner ear. These organs contain hair cells that are sensitive to movement of small calcium carbonate crystals called otoliths, which move in response to changes in linear acceleration. The other structures listed are involved in detecting rotational movement (the cochlea) and changes in rotational movement (the semicircular canals), or in sensing pain (nociceptors).
