A – Pillar cells
B – Outer hair cell
C – Deiters cell
D – Inner hair cell
In the inner ear, a channel formed by a latticework of bone spirals around in parallel to the coiled labyrinth.
This channel is called Rosenthal’s canal within which reside the somata of the spiral ganglion neurons.
Each cell body emits a peripheral process that extends toward the organ of Corti and a central process that projects into the auditory nerve.
The somata of spiral ganglion neurons lie in the Rosenthal canal.
· The central process of ganglion cells form the cochlear nerve.
· Spiral ganglion supplies both inner and outer hair cells
· There are two types of ganglion cells. Type 1 and type 2. Type 1 supplies the inner hair cell and type 2 supplies the outer hair cell
· 95% of fibres of spiral ganglion supplies the inner hair cells. Only 5% of them supply the outer hair cells.
