1. when an AP arrives at a synapse, which way do calcium ions move?

  • out of the presynaptic terminal into the cleft
  • into the presynaptic terminal
  • no movement across the cell membrane
  • into the postsynaptic terminal
  • out of the postsynaptic terminal into the cleft

2. which statement concerning the role of Ca2+ in the contraction of skeletal muscle is correct?

  • Ca2+ ions do not play a role in the contractile process
  • the mitochondria acts as a store of Ca2+ for the contractile process
  • a rise in intracellular Ca2+ allows actin to interact with myosin
  • the tension of skeletal muscle fibres is partly regulated by G proteins
  • Ca2+ entry across the plasma membrane is important in sustaining the contraction of skeletal muscle

3. regarding receptors in the skin:

  • the nociceptors of the skin are bare nerve endings
  • all sensory info from the skin reaches the brain via the ventral column of the spinal cord
  • all skin receptors are encapsulated
  • all sensory info from the skin reaches the brain via the dorsal column of the spinal cord
  • the receptive fields of touch receptors are uniform is all skin areas

4. regarding the basal ganglia in motor control:

  • parkinsons is caused by neuronal degeneration within the basal ganglia
  • disorders of the basal ganglia produce a marked loss of sensation
  • parkingsons is caused by neuronal degeneration within the motor cortex
  • the basal ganglia lie just outside the spinal cord
  • the basal ganglia are not involved in voluntary movement

5. which statement about the nervous system is NOT true?

  • each spinal segment gives rise to two pairs of spinal roots
  • the white and grey matter of the spinal cord is arranged in the same way as that in the cerebral hemispheres
  • grey matter contains the cell bodies and dendrites of neurones
  • each cerebral hemisphere is divided into 4 lobes
  • the dorsal root ganglia contains the cell bodies of the primary sensory neurones
