ANATOMY

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: -During the sixth week of development, semicircular canals appear as flattened diverticulae from the utricular portion of the otic vesicle. The central region of the walls of these projections appose each other, fuse, and disappear, giving rise to the three membranous semicircular canals.

Detailed explanation-3: -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-4: -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.
