Answer:
The correct answer is "semicircular canals".
Explanation:
The semicircular canals are three fluid-filled tubes located in the inner ear that provide balance to the body. The fluid that contain the semicircular canals is known as endolymph and it moves in continuity with the head, allowing to sense head movements and rotations. People that suffer from superior semicircular canal dehiscence syndrome (SSCD), experience vertigo and the appearance that stationary objects are moving.
