2. Where are central pattern generators found?

  • PMC
  • Somatosensory cortex
  • Spinal cord
  • Brainstem

3. Describe the main concept of the final common pathway

  • All output from the somatosensory cortex that results in an action passes from spinal cord/brainstem to a striated muscle fibre
  • All input from the somatosensory cortex that results in an action passes from spinal cord/brainstem to a striated muscle fibre
  • All output from the nervous system that results in an action passes from spinal cord/brainstem to a striated muscle fibre
  • All input from the nervous system that results in an action passes from spinal cord/brainstem to a striated muscle fibre

4. What is 'recruitment', which creates graded contractions?

  • The specific number of motor neurones and muscle fibres active at any given time
  • How many motorneurons and muscle fibres are activated at approximately the same time
  • The specific number of alphaneurones active at any given time
  • The average strength of the action potentials in the 'pool' of motorneurons for a given muscle

5. Which of these are characteristics of lower motorneurons (alpha motorneurons)

  • Large, conduct info at 120ms per second
  • Small, conduct info at 100ms per second
  • Small, conduct info at 120ms per second
  • Large, conduct info at 100ms per second
