Map the brain and spinal cord, count the cranial and spinal nerves, separate sympathetic from parasympathetic, and explain an action potential from resting potential to synapse.
Human Biology and Physiology is worth 15 of the 40 Zoology marks, the heaviest unit in the subject, and with eight chapters sharing them, the nervous system averages about two (MEC publishes weights by unit, not by chapter). MEC's scope line: CNS, PNS and autonomic nervous system; Nerve impulse. Three shapes of question:
