6. Which of these is not a way in which muscle force can be modulated?
- Lateral Excitation
- Frequency Modulation
- Size Principle
7. Which of these is false when considering lateral descending motor pathways?
- The terminations are focused on contralateral lateral interneurones and motorneurones
- They have a greater effect on extensors than flexors
- They control muscle groups in the limbs, mainly the distal parts
- They descend in the contralateral lateral funiculus
- They have a function in fine, independent dexterity
8. Muscle spindles (a type of stretch receptor) recieve motor supply from...?
- Delta motorneurones
- Gamma motorneurones
- Beta motorneurones
- Alpha motorneurones
9. 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
10. Which of these is not a way in which motor units can be activated?
- Spinal nerve reflexes
- Spontaneously
- Cranial nerve reflexes
- Descending motor pathways
11. Action potentials fired by 1a muscle spindle fibres increases when?
- The muscle spindle fibre is being stretched
- As the length of the muscle spindle fibre increases
12. Do type I motor units exhibit fast or slow responses?
