Vestibulocochlear Nerve Flashcards
Cochlear nerve terminates
Two cochlear nuclei, anterior and posterior
Where does the vestibular nerve terminate
Vestibular nuclear complex (superior, medial, lateral, inferior)
The cochlear nerve is composed of axons from
Spiral ganglion
Cochlear nerve is made up of bipolar neurons with cell bodies in the
Cochlear spiral ganglion
axons from the trapezoid nuclei form
the lateral lemniscus
Apparent origin of CN VII (vestibulocochlear)
Cerebellopontine angle
what is the inferior branch of the vestibular nerve composed of
saccular nerver, posterior ampullary nerve
what does the saccular nerve supply
the saccule
what does the posterior ampullary nerve supply
the posterior ampullary crest
what is the superior branch of the vestibular nerve composed of
lateral ampullary nerve, anterior ampullary nerve, voits nerve
voits nerve is a branch directly to
the saccule
the lateral ampullary nerve supples
lateral semicircular canal, utricle
tumor of schwann cells around CN VIII
acoustic neuroma
ringining in ears, first singn of meniere’s disease
tinnitus
