Detailed explanation-1: -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.

Detailed explanation-2: -The semicircular canals of each ear contain three main parts: anterior, posterior, and horizontal canals. Each of these canals provides a separate sense of directional balance, and each canal on the left is always paired with a canal on the right for normal function.

Detailed explanation-3: -Whereas the otolith organs are primarily concerned with translational movements, the semicircular canals sense head rotations, arising either from self-induced movements or from angular accelerations of the head imparted by external forces.

Detailed explanation-4: -The semicircular canals are three almost circular tubes, which contain fluid called endolymph. Endolymph is also found in the cochlear duct in contact with auditory hair cells.

Detailed explanation-5: -The vestibular system is the sensory apparatus of the inner ear that helps the body maintain its postural equilibrium. The information furnished by the vestibular system is also essential for coordinating the position of the head and the movement of the eyes.
