BasalGanglia And Cerebellum In Movement - Week 23

Question 1

What is the function of the basal ganglia?

Answer 1

Influences motor cortex via pathway through thalamus

Aids in planning, execution of smooth movement, the balance and maintenance of wanted and unwanted movement.

Question 2

What is the role of the cerebellum?

Answer 2

Regulates movement posture: controls movement synergy (fluidity of movement - rate, range, force, direction)

Question 3

What is the function of the cerebellum?

Answer 3

Receives input from motor cortex, proprioception from limbs, balance from inner ear

Cerebellum plans the movement, sends action potentials down spinal chord for muscle activation
