brain stem and the cerebellum Flashcards
(32 cards)
the brain stem is loacted
between teh cerebrum and the sc
the brain stem consists of the
midbrain , pons ,medulla oblongata
fucntion of the brain stem
produces autonomic behaviour necessary for surivival
provides a pathway for tracts running to and from the brain
mid brain located between
diencepholon and thepons
the mid brain is connected to the cerebellum because of the
superior cerebellar peduncles
what cranial nerves exit teh midbrain
3,4
the nuclei present in the midbrain are the
red nucleud and substania n on each side
the red nuckleus contains
numerous blood vessles
teh substantia n secretes
dopamine
loss of these neurons is associated iwth parkinsons disease
the midbrain dunctions as a
relay system
location of teh pons
between teh midbrain and teh medulla oblongata
it contains sensory and motor nucelei for 4 cranial nervs
5,6,7, and soem bramches of 8
the pons is connected tp the cerebellum because iof the
middle cerebellar peduncles
what nucelus does te pons have
respirator nucelus
help control breathing to maiintain respiratory rhythm
what part of teh brainstem is the most inferior region of the brain?
medulla oblongata
the medulla oblongata becomes teh spinal cord at the level of the
firamen magnum
2 medullary pyramids are visbile only
ventrally
the cranial nerves taht exit the medulla oblongata are the
rest of 8 ,9,10,11,12
what connects teh medulla oblongata tothe cerebellum
inferiro cerebellar peduncle
the appearnce of teh cerebullum superiorly and inferiorly
butterfly
what connects teh two lateral cerbellar hemispheres
the vermis
the cerebellar hemispheres
andteriro and posterior lobe and flocculonodular lobe
cerebellar cortex consists of
grey matter in parallel folds callled the folia
inner white matter of the cerebellum is aclled the
arbor vitae
