Explanation: 

Detailed explanation-1: -Next to the middle ear in the bone of the skull is a small compartment which contains the hearing and balance apparatus known as the inner ear. The inner ear has two main parts. The cochlea, which is the hearing portion, and the semicircular canals is the balance portion.

Detailed explanation-2: -The inner ear is composed of two parts: the cochlea for hearing and the vestibular system for balance. The vestibular system is made up of a network of looped tubes, three in each ear, called the semicircular canals.

Detailed explanation-3: -Loop-shaped canals in your inner ear contain fluid and fine, hairlike sensors that help you keep your balance. At the base of the canals are the utricle and saccule, each containing a patch of sensory hair cells.

Detailed explanation-4: -The semicircular canals are three tiny, fluid-filled tubes in the inner ear that help you keep your balance. When your head moves around, the liquid inside the semicircular canals sloshes around and moves the tiny hairs that line each canal.
