cranial nerve nuclei Flashcards
superior colliculus- M
Edinger-Westphal nucleus
motor
inferior colliculus- M
nucleus of trochlear nerve
motor
mid pons- M
motor nucleus of trigeminal
dorsal pons- M
nucleus of abducens
motor
caudal border of pons- M
motor nucleus of facial
border of pons and medulla- M
nucleus salvatorius superior- facial
nucleus salvatorius inferior- glossopharyngeal
dorsal medulla- M
motor nucleus of vagus
nucleus ambiguous- IX, X, XI
medulla between 4th ventricle- M
nucleus of hypoglossal
midbrain- S
mesencephalic nucleus of trigeminal
pons- S
main sensory nucleus of trigeminal
pons and medulla- S
vestibular and cochlear nuclei of acoustic nerve
dorsal medulla- S
nucleus of tractus solitarius- VII and IX
dorsal lateral medulla- S
nucleus of spinal tract of trigeminal
what are the 3 sensory nuclei of origin for the trigeminal nerve?
mesencephalic nucleus of trigeminal
main sensory nucleus of trigeminal
nucleus of spinal tract of trigeminal
motor nucleus of trigeminal for motor fx
cerebellopontine angle lesion:
V, VII, VIII
cavernous sinus lesion:
III, IV, V, VI
jugular foramen syndrome:
IX, X, XI
bilateral syndrome:
X, XI, XII
LMN: bulbar palsy
UMN: pseudobulbar palsy
motor nuclei origin
anterior horn cells of spinal cord
sensory nuclei origin
dorsal root ganglia of spinal nerves; outside brainstem
3 reasons more than 1 cranial nerve might be involved in lesion
- lesion is where several nerves run together
- generalized disorder (myasthenia gravis)
- multiple lesions ( MS, vascular disease)
