1.
the state of an unstimulated neuron or muscle cell in which the inside of the cell is relatively negative in comparison to the outside; the resting state.
2.
the loss of a state of polarity; the loss of a negative charge inside the plasma membrane.
3.
local change in membrane potential that varies directly with the strength of the stimulus; declines with distance.
4.
an electrical event occurring when a stimulus of sufficient intensity is applied to a neuron or muscle cell, allowing sodium ions to move into the cell and reverse the polarity.
5.
a self-propagating wave of depolarization; also called an action potential.
6.
restoration of the membrane potential to the initial resting (polarized) state.
7.
fluid-filled space at a synapse between neurons.
8.
automatic reaction to a stimulus.
9.
neural pathway for reflexes.
10.
involuntary reflexes that stimulate skeletal muscle.
11.
involuntary reflexes that regulate smooth muscle, heart, and gland activity.
