cochlear root of cranial nerve VIII

co·chle·ar root of cranial nerve VIII

one of the components of the vestibulocochlear nerve; it is made up of the central processes of the bipolar neurons that make up the spiral (cochlear) ganglion in the spiral canal of the modiolus of the bony cochlea; the cochlear root enters the cranial cavity by passing in fascicles through the spiral foraminous tract at the bottom of the internal auditory meatus; it enters the brainstem through the pontomedullary groove, closely adhering to the caudoventral aspect of the vestibular root, and distributes its fibers to the ventral and dorsal cochlear nuclei in the floor of the lateral recess of the fourth ventricle. Synonym(s): radix inferior nervi vestibulocochlearis
