2. Muscle spindles (a type of stretch receptor) recieve motor supply from...?

  • Gamma motorneurones
  • Alpha motorneurones
  • Beta motorneurones
  • Delta motorneurones

3. A stroke affecting the medial descending motor pathways will have?

  • Little effect because the pathways have bilateral terminations
  • A large effect because the terminations are contralateral

4. Which of these is false when considering lateral descending motor pathways?

  • They descend in the contralateral lateral funiculus
  • The terminations are focused on contralateral lateral interneurones and motorneurones
  • They control muscle groups in the limbs, mainly the distal parts
  • They have a greater effect on extensors than flexors
  • They have a function in fine, independent dexterity

5. Which of these is false when considering medial descending motor pathways?

  • The control muscles groups in the neck, trunk and proximal limbs
  • The terminations of this system are bilateral and widely dispersed
  • The main origin is the primary motor cortex
  • They descend in the ventral funiculus
  • They have an anti-gravity function
