AIIMS 2019 Zoology Nervous System MCQ Question

The utricle and saccule, located in the inner ear, are responsible for maintaining static equilibrium by detecting linear accelerations and the position of the head relative to gravity through specialized hair cells embedded in a gelatinous membrane. In contrast, the cerebrum primarily processes sensory information and higher cognitive functions, while the cerebellum coordinates voluntary movements and balance, but does not directly maintain static equilibrium. The semicircular canals are involved in detecting rotational movements rather than static positions. Thus, the utricle and saccule play a crucial role in our ability to perceive and maintain balance when stationary.
