AP PSYCHOLOGY

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: -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-4: -The semicircular canals consist of three ducts arranged on three perpendicular planes, with each duct looping back at different angles. The ducts are situated at right angles from each other; similar to the way that three sides of a box come together at a corner.

Detailed explanation-5: -The fluid that fills the three semicircular canals-the lateral (horizontal), anterior, and posterior-remains in place while the head moves. As a result, each one delivers specific information about balance and body position, assisting in maintaining steady vision even in motion and synchronising total activity.
