  • Suggest why naked mole rats do not feel pain when exposed to acid
    There is no action potential in repsonse to acid stimulus since no sodium ion voltage gated channels open. This means that only few sodium ions move in causing less depolarisation, not enough for an action potential
  • Why transmission of action potentials along the axon slower in the absence of saltatory conduction
    No nodes of Ranvier so the whole axon needs to be depolarised
