B) we can see the world in three dimensions
C) we can detect sound locations in the three-dimensional world
D) we have an extra if one is broken

D) we have an extra if one is broken

Quizplus · Accepted Answer

The semicircular canals are oriented perpendicular to each other, allowing the detection of rotational movements in three planes (pitch, yaw, and roll), which is important for maintaining balance and spatial orientation. Having three canals ensures that each plane of motion is covered by one canal.
