Lab 03 Flashcards
medullary olives
motor learning and function - cerebellum
aid in auditory perception
medullary pyramids
white matter tract carrying axons from brain to spinal cord
pyramidal decussation
where white matter tracts cross over each other
pons
taste and sensation to face
hearing and balance
fasciculus cuneatus
carries touch, pressure, proprioception sensation from upper limbs
fasciculus gracilis
carries touch, pressure, proprioception from lower limbs
superior colliculi
visual integration
inferior colliculi
auditory integration
superior cerebellar peduncles
output info to cortex
middle cerebellar peduncles
connects pons to cerebellum
inferior cerebellar peduncles
input and output to cerebellum
cerebral peduncles
white matter tract relaying information between brain and spinal cord
periaqueductal gray
pain modulation
red nucleus
motor coordination
beginning of the rubrospinal tract
substantia nigra
produces dopamine
implicated in parkinson’s
ponto-cerebellar arteries
white matter tract carrying information from pons to cerebellum
corticospinal tract (spinocerebellar tract)
white matter tract carrying information from spine and cerebellum
anterior lobe of cerebellum
mediates unconscious proprioception
connects cerebellum to spinal cord
flocculonodular notch
balance and muscle tone
connects vestibular nuclei to spinal cord
posterior lobe of cerebellum
fine motor control
inhibits involuntary movements
connects brainstem and cerebral cortex to cerebellum
tonsils
round shaped lobule under cerebellum
implicate in type 1 chiari malformation
vermis
body posture and locomotion
damage to anterior lobe
loss of motor coordination; seem drunk
damage to flocculonodular lobe
loss of axial muscle coordination
deficits in visual tracking
oculomotor control
damage to posterior lobe
intention termors
dysmetria
type 1 chiari malformation
cerebellar tonsils are elongated, get pushed through foramen magnum and obstruct CSF flow
