   2.   Know the 3 classes of neurons and their functions.

   3.   Know the following neuron structures and what they do:  dendrites, cell body,
         axons, myelin   sheath,   Schwann cell, nodes of Ranvier.  Know various types
         of Neuroglia cells.

   4.   Be familiar with these terms:  nerve impulse, resting potential, action potential
         threshold.

   5.   Know the terms synapse and neurotransmitter, and various neurotransmitters.

   6.   Know the following:  peripheral nervous system, somatic system (division),
         autonomic system (division), sympathetic division, parasympathetic division,
         reflex arc.

   7.   Know the following:  central nervous system, dura, pia & arachnoid meninges,
         cerebrospinal fluid, gray matter, white matter, ascending tract, descending tract.
