  2. 4 brain regions
  3. sensory nerve
  4. action potential
  5. midbrain
  1. a part of central nervous system beginning inferior to brainstem down to L2 vertebrae;
    conducts sensory info to brain and motor commands from brain to muscles;
    center is gray matter; external is white matter;
    CSF in central canal and surrounding cord
  2. b cerebrum
    diencephalon
    cerebellum
    brain stem
  3. c aka affarent nerve;
    carries sensory information (APs) to CNS
  4. d quick electrical charge that travels "down" an axon towards synapse; Na+, K+, and Ca++ ions vital to this function; causes neurotransmitter release at synapse;
    aka neural impulse or "electrical signal"

    named for location on vertebrae (8C, 12T, 5L, 5S, 1C);
    composed of 2 roots: dorsal and ventral
  4. 1 of 4 cavities in brain, which creates and is filled with cerebrospinal fluid
