Lecture 24: Motor Control

Question 1

What do the neurons in the prefrontal cortex do

Answer 1

Neurons involved in decisions to
move; planning the desired
movement outcome

Question 2

What do the neurons in the premotor cortex do

Answer 2

Neurons involved in organizing movement sequences to achieve the outcome

Question 3

What do the neurons in the Primary motor cortex do

Answer 3

Neurons involved in directing voluntary movement

Question 4

What does the Basal Nuclei do

Answer 4

Refine movements, selects which to allow and which to inhibit

This is done by altering sensitivity of neurons projecting into the corticospinal or other pathways

Question 5

What is the role of the cerebellum in motor control

Answer 5

Stores and facilitates learning, planning, execution of motor programs

Question 6

What is movement of the limbs controled by

Answer 6

The corticospinal pathway

Question 7

Describe the corticospinal pathway

Answer 7

Upper motor Neurons in primary motor cortex
lower motor neurons in spinal cord
To skeletal muscle

Question 8

What is the Nueromuscular junction

Answer 8

the communication point between nerves and skeletal muscle
