The number of neurons in the spiral ganglion is estimated to be about 35,000–50,000. [1] Two apparent subtypes of spiral ganglion cells exist. Type I spiral ganglion cells comprise the vast majority of spiral ganglion cells (90–95% in cats and 88% in humans [2]), and exclusively innervate the inner hair cells. They are myelinated, bipolar ...
The cochlear nerve, as well as spiral ganglion is situated inside it. The cochlear nerve conducts impulses from the receptors located within the cochlea. The picture shows the osseous labyrinth. The modiolus is not labeled; it's at the axis of the spiral of the cochlea.

Receptors are located throughout the body including the skin, epithelia, internal organs, skeletal muscles, bones, and joints. The cutaneous receptors of the skin project in an orderly fashion to the spinal cord , and from there, via different afferent pathways ( dorsal column-medial lemniscus tract and spinothalamic tract ), to the ventral ...
