motor function

Question 1

control of voluntary movements: 2 types of tracts

Answer 1

pyramidal and extrapyramidal

Question 2

control of voluntary movements: 2 pyramidal tracts

Answer 2

lateral and anterior corticospinal tracts

Question 3

control of voluntary movements: 3 extrapyramidal tracts and overall function

Answer 3

rubrospinal tract, reticulospinal tract, vestibulospinal tract; modify motor function

Question 4

control of voluntary movements: rubrospinal tract location and function

Answer 4

automatic movements of arm in response to posture/balance changes; from red nucleus in midbrain down to spinal cord

Question 5

control of voluntary movements: reticulospinal tract

Answer 5

coordinate automated movements of locomotion and posture e.g. to painful stimuli

Question 6

control of voluntary movements: vestibulospinal tract

Answer 6

facilitate mainly alpha motor neurones to maintain erect posture and balance, anti-gravity extensor muscles
