shorter Neuro lab final secondary Q's Flashcards
area that surrounds the cerebral aqueduct that receives nociceptive info
periaqueductal grey
region that receives nociceptive info and projects to the serotonergic raphe nuclei–> part of a major pain-inhibiting pathway in the SC
periaqueductal grey
periaqueductal grey is a part of the _____ pathway in the SC
pain inhibiting pathway
tract that connects the vestibular nuclei with CN III, IV, and VI (occulomotor, troch, abducens)
Medial Longitudinal Fasciculus
tract that regulates vestibulo-occular reflexes and coordinations
medial longitudinal fasciculus
Descending fibers of voluntary motor control from the cortex and projecting to spinal cord (corticospinal and corticobulbar tracts). At the level of the midbrain, cortical input is ispilateral.
crus cerebri
crus cerebri has descending fibers of voluntary _____ control from the cortex and project to the SC
motor
crus cerebri contains what two tracts
corticospinal
corticobulbar
Sends descending fibers down to the rostral spinal cord via the rubrospinal tract
Red Nucleus
2 portions of the substantia nigra
pars compact (dop) pars reticulata (visual tracking)
neuronal loss in the ____ = Parkinsons
pars compacta
Parasympathetic, preganglionic nucleus of CN III.
nucleus of edinger westphal
EWN regulates pupillary light respinse through projections to the ____
ciliary gg (post gg that innervate the sphincter pupillae)
responsible for the accomidation reflex
nucleus of edinger westphal
Lower motor neuron nucleus of CN III.
oculomotor Nucleus
Part of the midbrain tectum (roof) that is involved in eye tracking and saccades.
superior colliculus
Part of basal ganglia circuit involving substantia nigra pars reticulata. Receives afferent input from frontal eye fields and visual association cortices and sends motor output to occulmotor nuclei and to the head and neck via the tectospinal tract.
superior colliculus
superior colliculus sends efferent info to the occulomotor nuclei, head and neck via the ____ tract
tectspinal tract
ventral portion of the pons
basis pontis
basis pontis carries the fibers of (4) nuclei
cortico-ponto-cerebelllar
corticospinal
corticobulbar
pontine nuclei
Space in ventral hindbrain containing CSF to cushion brain and provide nutrients. Contains choroid plexus.
IV ventricle
Dorsal portion of the pons
pontine tegmentum
comprises the floor of the floor of the IV ventricle
pontine tegmentum
cortico input travels ipsi to the pontine nucleus and then travels through the _____ to enter the cerebellum
middle cerebellar peduncle
coordinated movement info
