CN 2 - Herring Flashcards
Supplies somatic sensory from the posterior 1/3rd of the tongue & middle ear
CN IX
Supplies taste from posterior 1/3rd of the
tongue
CN IX
nerve that causes ear infection pain
CN IX
Supplies somatic motor innervation to 1 pharyngeal muscle
CN IX
PreGPS to the parotid gland
CN IX
Supplies visceral sensory (reflex) from the carotid body & sinus and oropharynx
CN IX
where are the lower motor neurons located in the somatic motor pathway for CN IX
nucleus ambiguous
what is the peripheral target for the CN IX in the somatic motor pathway
stylopharyngeus muscle
where are the preGPS cell bodies located in the PS pathway for CN IX
inferior salivary nucleus
what 2 structures do the preGPS fibers form in the PS pathway for IX
tympanic plexus
lesser petrosal n
where are the postGPS CBs located in the PS pathway for CN IX
Otic ganglion
the postGPS fibers hitch a ride on what CN in the PS pathway of CN IX
CN V3
what is the peripheral target of the PS pathway of CN IX
parotid gland
the 1st order neurons in the inferior ganglion of CN IX for the somatic sensory pathway of CN IX contribute to what
posterior 1/3 of tongue
the 1st order neurons in the superior ganglion of CN IX for the somatic sensory pathway of CN IX contribute to what
middle ear & inner aspect of tympanic membrane
In the somatic sensory pathway for CN IX, the central processes from ganglia project to 2nd order cell bodies in the
spinal trigeminal nucleus
In the somatic sensory pathway for CN IX, 2nd order CBs send their axons to 3rd order neurons in the
VPM of the thalamus
In the somatic sensory pathway for CN IX, 3rd order neurons send their axons to the
inferolateral postcentral gyrus
In the visceral sensory pathway for CN IX, the 1st order CBs in the inferior ganglion of CN IX contribute to what 3 things
carotid body
carotid sinus
oropharynx
In the visceral sensory pathway for CN IX, the central processes from ganglia project to 2nd order CBs in the
solitary nucleus
In the visceral sensory pathway for CN IX, the 2nd order CBs primarily projects fibers through ______ pathways
reflex
In the special sensory pathway for CN IX, the 1st order CBs in the inferior ganglion of CN IX have peripheral process that travel from ________ to inferior ganglion of CN IX
posterior 1/3 tongue
In the special sensory pathway for CN IX, central process from the inferior ganglion of CN IX project to 2nd order CBs in the
solitary nucleus
In the special sensory pathway for CN IX, 2nd order CBs send their axons to 3rd order neurons in the
VMP of the thalamus
In the special sensory pathway for CN IX, 3rd order neurons send their axons to the
Insula (gustatory cortex)
decreased gag reflex is due to a lesion of CN
IX
decreased pain, temperature, and touch form the posterior 1/3 of the tongue is due to a lesion to CN
IX
variable presentation of abnormal taste is due to a lesion of CN
IX
