Spiral Channel

The spiral canal (lat. canalis spiralis) is part of the cochlea of ​​the inner ear. It is a spirally twisted canal running from the base of the cochlea to its apex.

The spiral canal contains a spiral organ - the hearing receptor, consisting of hair cells that convert sound vibrations into nerve impulses. The canal is filled with endolymph. Vibrations of the basilar membrane cause movement of the endolymph, which in turn leads to displacement of the hairs of the spiral organ and stimulation of the auditory nerve fibers.

Thus, the spiral canal plays an important role in conducting and amplifying sound in the inner ear.
