This name reflects the fact that the cell bodies, considered as a unit, have a spiral (or perhaps more accurately, a helical) shape, reflecting the shape of the cochlea. The terms 'cochlear nerve fiber' and 'spiral ganglion cell' are used, to some degree, interchangeably, although the former may be used to more specifically refer to the central axons of the cochlear nerve. These central axons exit the cochlea at its base, where it forms a nerve trunk. In humans, this aspect of the nerve is roughly one inch in length. It projects centrally to the brainstem, where its fibers synapse with the cell bodies of the cochlear nucleus TAO:0000588 The group of neuron cell bodies associated with the eighth cranial nerve during embryogenesis; splits in later development to form the cochlear and vestibular ganglia.
