exam two (ch.14) Flashcards
highest level of motor control involves association areas and basal ganglia which functions to
devise strategy
the middle level of motor control involves the primary motor cortex and cerebellum which funtion to
fine tuning strategy
execution of the motor strategy which is controlled by what structures
brain stem and spinal cord
_____ system influences all levels of the motor system
somatosensory
lateral pathways have cortical control and they do what movements
voluntary movements of distal limbs
ventromedial pathways of the brain stem control
postural muscles
the rubrospinal tract originates in ___ ___ (midbrain)
red nucleus
what motor pathways controls posture and locomotion in the brain
vestibulospinal and tectospinal and pontine reticulospinal and medullary recticulospinal
motor pathway that is ventromedila and does head balance and head turning
vestibulospinal
motor pathway that is ventromedial and does orienting response
tectospinal
the ventriomedial pathways originate where
brain stem
ventromedial pathway that enhances antigravity
reflexes of the spinal
cord (maintain
standing)
pontine reticulospinal
ventromedial pathway that liberates antigravity
muscles from reflex
(opposite of the other
tract)
medullary reticulospinal
area 4 in the motor cortex is commonly called
primary motor cortex or M1
area 6 in the motor cortex is commonly called
higher motor area
the lateral region of the higher motor area is the ___ ____; the medial region is _____
premotor area and supplementary motor area
Microstimulation of prescribed
area of M1 normally elicits
whisker movement; Cut nerve that supplies whisker
muscles; Microstimulation now causes forelimb movement, this is an example of?
neuroplasticity (rewiring M1)
area 5 and 7 are involved in _____ somatosensory processing
complex
