Uberon definition : 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;
Uberon synonym : ganglion VIII; auditory ganglion; statoacoustic ganglion; acoustic ganglion VIII; acoustico-vestibular VIII ganglion; statoacoustic (VIII) ganglion; statoacoustic ganglia; gVIII; vestibulocochlear VIII ganglion;
Uberon related term : vestibulocochlear ganglia; acoustic ganglion; auditory ganglion; statoacoustic VIII ganglion;
Uberon broad term : SAG;
Uberon Homology note : (During the development of the inner ear in a vertebrate embryo) As the otic placode
invaginates into a cup neuroblasts delaminate from the anterior ventral aspect of
the otic epithelium to give rise to neurons of the vestibulocochlear (statoacoustic)
ganglion of cranial nerve VIII.[well established][VHOG];
Uberon Terminology note : The cell bodies of the cochlear nerve lie within the central aspect of the cochlea
and are collectively known as the spiral ganglion. 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;
