cerebellar function HY Flashcards
definition of superior colliculus
functions in the control of reflex movements that orient the eyes, head, and neck in response to visual, auditory, and somatic stimuli
periaqueductal gray matter
function in the processing of autonomic movements and limbic activities, as well as modulation of nociception
aqueduct
passageway connecting the third and fourth ventricles
nucleus of eidneger-westphal
parasympathetic innervation of the eye to constrict the iris and to the ciliary muscle to alter lens shape after accomodation
cranial nerve II nuclei and nerve
motor control of eye muscles
spinothalamic tract
fiber pathway to thalamus for pain/temp from the periphery
meidal lemniscus
sensory pathway for proprioception connecting the nucleus gracilis and cuneatus with the thalamus
medial geniculate
sensory pathway for proprioception connecting the nucleus gracilis and cuneatus with the thalamus
lateral geniculate
thalamic relay nuclei for auditory information
cerebral penducle
fiber bundles of the corticospinal tract connecting the cerebral cortex to the brainstem
optic tract
optic fibers from optic chiasm to the lateral geniculate
substantia nigra
one of several nuclei involved in smooth motor control; degenerates in Parkinson’s diseae
red nucleus
relay nuclei between the cerebellum to the thalamus
medial longitutdinal fasciculus
fiber pathway btw the vestibular nuclei and the CN nuclei 3, 4, 6 to coordinate head/eye movement
superior cerebellar peduncle
fiber pathway to and from the cerebellum
middle cerebellar peduncle
fiber pathway to and from the cerebellum
mesencephalic, main snsory nucleus, motor nucleus of V
three nuclear components of the trigeminal nerve nuclei
CN5
mtor and sensory fibers of CN 5
pontine nuclei
collection of neurons in the pons that receive input from the neocortex and send crossing fibers through the middle cerebellar peduncle
locus cerlueus
a noradrenegric brainstem nucleus involved in mood, sleep/wake cycle
raphe nucleus points
one of several serotonin type nuclei involved in mood, sleep/wake cycle
corticospinal tract
motor fibers from neocortex to spinal interneurons and lower motor neurons
nuclei of the vestibular system that regulate balance
inferior and medial vestibular nuclei
nucleus and tractus solitarius
sensory nuclei for taste (from CN VII) glands, chemo/baroreceptors (CNs IX, X)
drosal motor nculeus vagus (CNX)
parasymapthetic motor nucleus to lungs and gut
spinal nucleus and tract of CN V
nuclear andtract components of CN V that exten into the upper cervical cord
inferior olivary nculeus
origin of the climibing fibers to the cerebellar purkinje cells
pyramid
name give to the corticospinal tract fibers in the medulla
reticular formation
a network of neurons and axons that reside in the brain stem tegmentum involved in arousal, respiration, heart rate control
nucleus CN IX
glossopharyngeal nucleus with motor control over tongue and pharyngeal muscle with taste from posterior 1/3 of tongue
