|
Abducens Nerve |
Arise from the basal plate of myelencephalon and terminate in the external rectus muscle of the eyeball. |
|
|
True |
True or False When the abducens nerve contracts, it rotates the eyeball outward (abduction). |
|

1st motor fibers |
Arise from the basal plate of myelencephalon and synapse with the 2nd motor fibers in the geniculate ganglion |
|
|
Geniculate ganglion |
Carries motor impulses to the facial muscles |
|
|
Auditory Nerve |
Sensory; presents an acoustic ganglion beneath the auditory vesicle, caudal to the geniculate ganglion of CN VII |
|
|
Spiral ganglion |
Gives off short afferent nerve fibers that supply the cochlear duct and receive stimuli for the sense of hearing. |
|
|
Vestibular ganglion |
Gives off short afferent nerve fibers that supply the semicircular canal, utricule and Saccule and receive stimuli for the sense of equilibrium |
