Question

Even in complete darkness, we are able to maintain posture and equilibrium of our body with the help of

• A. Organ of corti
• B. Vestibular apparatus
• C. Cochlea
• D. Scala tympani

Answer 1

The correct option is B Vestibular apparatus

Sensory information about motion, equilibrium, and spatial orientation are provided by the vestibular apparatus, which in each ear includes the utricle, saccule, and three semicircular canals. The utricle and saccule detect gravity (information in a vertical orientation) and linear movement.

So, the correct option is 'Vestibular apparatus'.
