Question

The structures in a body that assist in body balance are located in
A. Middle ear
B. Inner ear
C. Eustachian tubes
D. None of the above

Answer 1

Hint: The vestibular system containing the structures- three semicircular canals, utricle, and saccule at the deep end of the ear monitors balancing of the body.

Complete answer: The inner ear is majorly responsible for monitoring balance in the body. The three semicircular canals have a fluid and they are arranged at an angle of 90° to each other and they terminate in a space that has small hair cells in it.
These spaces are referred to as ampullae.
Within a short span of time, the fluid-filled in the semicircular canals and ampullae also starts moving.
This suggests that the sensory hair cells in the ear get bent by the slowly moving fluid.
The hair cells then transmit this information towards the brain through auditory nerves. There is another part called the otolith organ situated diagonally under the semicircular canals and they too assist in this process.

Therefore, the correct answer is option B. Inner ear.

Note: It is noteworthy that the main function of the ear is to assist in body balance and hearing is an additional task performed by the ear.
In the situations where we turn or tilt our head, the inner ear also does the same.
