Brainstem Flashcards
What can you see in a rostral brainstem section?
the olive of medulla. most rostral has cerebral peduncles
Where are CN IX-XII nuclei located?
the medulla
Nuclei of caudal medulla
Tracts of the medulla
Entire cross section of caudal medulla
Entire cross section of rostral medulla
medulla nuclei: balance, location in space
vestibular
medulla: does motor learning
inferior olivary complex
medulla: descending motor tracts
pyramids
medulla: location information from the body/spine to the cerebellum (Proprioception)
spinocerebellar tracts
medulla: pain and temperature tract
spinothalamic tract
medulla: motor nucleus for hypoglossal nerve (tongue)
hypoglossal nucleus
medulla: motor nucleus (soft palate, pharynx, larynx: speech and swallowing) for cranial nerves 9, 10, 11. If there’s lesion there’s dysphagia, dysphonia, deviated uvula
nucleus ambiguus
medulla: motor nucleus (parasympathetic for vagus)
dorsal motor nucleus of vagus
medulla: Touch from the lower body (below T6)
nucleus gracilis
medulla: Touch for the upper body (above T6; not face)
nucleus cuneatus
medulla: taste tongue CN 7, 9, 10
solitary nucleus
medulla: CN9, parasympathetic, parotid gland)
inferior salivary gland
pons cross section
pons: nuclei: balance, location in space
vestibular
pons nerve Touch and Proprioception face
principle V
pons nerve muscles mastication
motor V
pons nerve Touch and pain/temperature face
spinal V
pons nuclei: muscles facial expression
facial nucleus
pons nuclei parasympathetic VII doing lacrimal, submandibular, sublingual, nose mucosa
superior salivary
pons nuclei lateral rectus muscle
abducens nucleus
pons tracts for location information from the body/spine to cerebellum (proprioception) that runs through inferior cerebellar peduncle
spinocerebellar tracts
pons ascending tract for touch
medial lemniscus
pons tract for Motor information cortex-spinal cord
corticospinal
pons tract for Motor information cortex-brainstem (head/neck)
corticobulbar
pons tract with part of the corticobulbar, motor information to the pontine nuclei
corticopontine
midbrain cross section
midbrain nuclei that is parasympathetic for pupil constriction
Edinger-Westphal nucleus
nucleus in midbrain for eye motor
oculomotor
midbrain nucleus for superior oblique eye motor
trochlear nucleus
nucleus in midbrain for proprioception head
mesencephalic
nucleus in midbrain for motor coordination
red nucleus
nucleus for motor learning/motor planning in midbrain
substantia nigra
nucleus in midbrain for pain modulation (based on emotion)
periaqueductal grey
nucleus in midbrain for visual reflexes
superior colliculus
nucleus in midbrain for auditory processing
inferior colliculus
entrance for corticospinal/corticobulbar/corticopontine motor tracts in midbrain
cerebral peduncle
touch tract in midbrain
medial lemniscus path
pain/temp tracts in midbrain
spinothalamic tract
substantia nigra
motor learning, motor planning, eye movement, reward
