Glial cells (glia)

✔️cells in the nervous system that support, nourish, and protect neurons; they
also play a role in learning, thinking, and memory. (Myers Psychology for AP 3e p.
82)



Action potential

✔️a neural impulse; a brief electrical charge that travels down an axon. (Myers
Psychology for AP 3e p. 83)



Threshold

✔️the level of stimulation required to trigger a neural impulse. (Myers
Psychology for AP 3e p. 83)



Refractory period

✔️ (1) in neural processing, a brief resting pause that occurs after a neuron has
fired; subsequent action potentials cannot occur until the axon returns to its
resting state.

(2) in human sexuality, a resting period that occurs after orgasm, during
which a person cannot achieve another orgasm. (Myers Psychology for AP 3e pp.
