1. What characterises lower motorneurone disease?

  • Issues with muscle tone, muscles contracted maj of time. Cant maintain posture. Cant inhibit spontaneous movementaIssues with muscle tone, muscles contracted maj of time. Cant maintain posture. Cant inhibit spontaneous movement
  • Issues with setting posture, initiating movement and controlling movement. Show intention tremors
  • Paralysis, muscle wasting, spontaneous contractions (fasciculation) and no reflexes
  • Can only activate few striate muscle fibres. Characteristic weakness in general postureCan only activate few striate muscle fibres. Characteristic weakness in general posture

2. What chemical is released into the junction binding to receptors on the end plate to cause action potentials in the muscle surface membrane?

  • Actin
  • Calcium
  • Acetylcholine
  • Dystrophin

3. Within the spinal cord, what does the gray matter contain?

  • Axons
  • Dendrites
  • Nerves
  • Finer pathways

4. In terms of facial muscle connectivity, upper motorneuron lesions cause?

  • No input to upper OR lower face on the whole of one half of face
  • No input to lower part of one half of face
  • No input to upper OR lower face on the whole of both halves of face
  • No input to upper part of one half of face

5. How is spinal cord mapping (gray matter) different from cortical mapping?

  • Different sections of spinal cord control diff muscles e.g proximal muscles are mapped diff to distal muscles. Cortical mapping is mapped by movements
  • Cortical mapping is mapped by muscles, different areas of the cortex control different muscles. Spinal cord mapping is mapped by movements
