Question

Quizplus · Accepted Answer

The three semicircular canals in the inner ear are oriented perpendicular to each other and detect angular or rotational movements of the head in the three planes of motion - yaw, pitch, and roll. This allows us to have a sense of balance and spatial orientation in our three-dimensional environment. The semicircular canals do not play a role in detecting sound locations or preventing motion sickness.
