movement control and coordination

Question 1

VESTIBULOCEREBELLUM:
Role:

Answer 1

balance + posture + gait during standing and locomotion.

Coordinate head and eye movments

Question 2

VESTIBULOCEREBELLUM:

inputs

Answer 2

vestibular and visual systems

Question 3

SPINOCEREBELLUM:

role

Answer 3

Role: control of limb movments while they are happening-ie coordiantes muscles so that movment is fluid

Question 4

SPINOCEREBELLUM:

inputs

Answer 4

Inputs:
ascending sensory info from spinal cord.
contralateral Motor cortex

Question 5

CEROBROCEREBELLUM

role

Answer 5

planning, modifying, learning movements- ie sothat as movments are repeated, they get smoother
cognitive functions

Question 6

CEROBROCEREBELLUM

Inputs

Answer 6

contralateral cerebral cortex

Question 7

area 4 aka primary motor cortex aka M1

Answer 7

execution of movement

• Ie voluntary movment control

Question 8

area 6 aka premotor area

Answer 8

sensory guided movements, control of proximal and trunk muscles

Question 9

supplementary motor area aka area 6 as well

Answer 9

• SMA proper &

pre-SMA

Question 10

• pre-SMA

Answer 10

: acquiring new motor sequences

Question 11

SMA proper:

Answer 11

planning of motor actions, especially those guided from memory
♣ Eg rehearsing a movement in mind but not actually doing it

Question 12

area 5&7 aka posterior parietal cortex (PPC)

Answer 12

asdfasdf

Question 13

area 5

Answer 13

receives somatosensory info from areas 1,2,3

Question 14

area 7

Answer 14

receives visual and proprioceptive info

Question 15

cerebellum job overview- helps to refine movment

Answer 15

adjusts your posture and gait

refines movments as you’re doing it

improves repetitions of the same movement
