Cochlea: innervation
Peripheral dendrites of the vestibulocochlear nerve (CN VIII) innervate hair cells of the organ of Corti and then pass medially through the osseous spiral lamina to the spiral ganglion, location of their bipolar nerve cell bodies. Central axons form the cochlear division of the nerve. The modiolus with its osseous spiral lamina provides a framework for the cochlea and a conduit for the nerve. 40x, 200x.
