The labyrinth has three components: 

Cochlea (containing receptors for hearing)

Semicircular canals (containing receptors that respond to head rotation)

Otolith organs (containing receptors that respond to gravity and head tilt)

The bony labyrinth is a series of channels and filled with a fluid called perilymph, which has a relatively low concentration of K+, similar to that of plasma or the cerebral spinal fluid

The membranous labyrinth more or less duplicates the shape of the bony channels and is filled with a K+-rich fluid called endolymph

The upper scala vestibuli and the lower scala tympani contain perilymph and communicate with each other at the apex of the cochlea through a small opening called the helicotrema
