Cochlear ganglion

Cochler ganglion is placed in lamina spiralis ossea and it contains mainly bipolar neurons (only 10 % are pseudounipolar neurons) – 1. N of the acoustic tract. Their dendrites surrounds bases of inner and outer hair cells together with axons of the controll acoustic pathways. Their axons (cochlear nerve) run from the cochlear ganglion through the modiolus (canales longitudinales modioli) to lower anterior part of the fundus of internal acoustic meatus (tractus spiralis foraminosus) and they joint the vestibular nerve to form the vestibulocochlear nerve.
