Semicircular canals
The three semicircular canals per ear are interconnected, fluid-filled tubes that are positioned almost at right angles to each other and belong to the balance organ in the inner ear (vestibular apparatus). They serve to register angular accelerations, i.e., rotational movements of the head.

Ear
The ear is not only the organ of hearing, but also of balance. A distinction is made between the outer ear with the auricle and external auditory canal, the middle ear with the eardrum and ossicles, and the actual hearing and balance organ, the inner ear with the cochlea and semicircular canals.

Macular organs
Together with the semicircular canals, the macular organs form the vestibular system in the inner ear of vertebrates. They consist of two structures positioned perpendicular to each other, the saccule and the utricle. This alignment enables the macular organs to perceive linear accelerations of the body in space along all three spatial axes: up-down, front-back, left and right.

Hair cells
Sensory cells in the inner ear located in the organ of Corti and the semicircular canals. The hair cells in the organ of Corti are responsible for transducing (converting) the vibrations into electrical potentials. Each of these sensory cells has hair-like protrusions of varying lengths, called stereocilia. These are interconnected. The movement of these stereocilia caused by the vibrations is the key to signal transduction in the hair cells.
