6. What is the function of the reticulospinal tract?

  • Medial reduces tone and lateral increases it
  • Control extensors of the arm and flexors of the legs
  • Lateral reduces tone and medial increases it
  • Control flexors of the arm and extensors of the legs

7. Where does the corticospinal tract divide into the anterior and lateral tracts?

  • The medulla
  • The spinal cord
  • The crus cerebri of the pons
  • The midbrain

8. What is the function of the vestibulospinal tract?

  • Coordination of head movement
  • Control flexors of the arms and extensors of the legs
  • Alters tone of muscle
  • Fine control of hand movements

13. Which of these statements is true?

  • The sensory cortex is the same as the precentral gyrus

  • Ipsilateral loss of proprioception
  • Contralateral loss of pain

18. The dorsal column medial lemniscus carries what information?

  • Touch and vibration
  • Pain and temperature
  • Crude touch and pressure
