Control of Movement

Question 1

8 Steps of Movement Control

Answer 1

1) Visual Info required to locate target
2) Frontal-Lobe motor areas plan the reach and command movement
3) Spinal cord carries info to the hand
4) Motor neurons carry messages to muscles of hand and forearm
5) Sensory receptors in fingers send message to sensory cortex that object has been grasped
6) Spinal cord carries information to the brain
7) Basal ganglia judges grasp forces, and cerebellum corrects movement errors
8) Sensory cortex receives message that cup has been grasped

Question 2

3 Main functions of Spinal Cord

Answer 2

1) Conducts sensory input from body (periphery) to the brain
2) Conducts motor output from brain to body
3) Acts as a reflex centre for survival

Question 3

4 Anatomical Aspects of the Spinal cord

Answer 3

1) about 45cm long
2) does not extend entire length of vertebral canal
3) Divided into 31 segments, at every segment, right and left (form sensory and motor, mixed)
4) Covered by meninges

Question 4

4 Cortical Lobes

Answer 4

Frontal Lobes
Temporal Lobes
Occipital Lobes
Parietal Lobes

Question 5

Frontal Lobe

Answer 5

motor and executive functions

Question 6

Temporal Lobe

Answer 6

visual, auditory and gustatory functions

Question 7

Gustatory

Answer 7

taste

Question 8

Occipital Lobe

Answer 8

visual functions

Question 9

Parietal Lobe

Answer 9

tactile functions

Question 10

3 Main Cortical Areas

Answer 10

Primary Motor Cortex
Supplementary motor cortex
Premotor cortex

Question 11

Where do phantom limb and homunculus occur

Answer 11

Primary motor cortex

Question 12

3 Aspects of the Basal Ganglia

Answer 12

• Part of the forebrain
• Responsible for amplitude and direction of movement
• Automatic movements

Question 13

4 Aspects of the Cerebellum

Answer 13

• 2 hemispheres
• complex movement (timing/coordination)
• balance, posture, stability
• feedback for control of movement
