True or False: Static equilibrium is controlled by sensory hairs within the ampulla of the semicircular canals.

Static equilibrium refers to the ability to maintain balance when the body is at rest or in a stable position. It is primarily governed by the vestibular apparatus of the inner ear, specifically the otolith organs, which include the utricle and saccule. These structures contain sensory hair cells that detect changes in head position relative to gravity and provide information about linear acceleration.

The ampulla of the semicircular canals, on the other hand, is associated with dynamic equilibrium, which is the sense of balance when the body is in motion or experiencing rotational movements. The sensory hairs located within the ampulla respond to the movement of fluid through the semicircular canals during head rotation, helping to detect changes in angular motion rather than static positioning.

Thus, the statement is false because static equilibrium is not controlled by the sensory hairs in the ampulla, but rather by different structures within the vestibular system.
