Question

Static balance is maintained by

• A. Maculae
• B. Cristae
• C. Organ of Corti
• D. Reissner's membrane

Answer 1

The correct option is A Maculae

Macula is a projecting ridge of saccule and utricle which are otolith organs in vestibular apparatus of inner ear. Vestibular apparatus controls equilibrium and maintains balance of body. When the head changes position due to movements, otoliths in gelatinous membrane come in contact with sensory hair cells and impulses are generated. The impulses are carried by the auditory nerves for interpretation in cerebellum which then sends signal and static balance is restored.

So, the correct answer is 'Maculae'.
