Nerve Impulses
The nerve impulse is the electrical message that is transmitted down the axon of a neuron. It doesn't travel directly down the axon, but is regenerated at points along the way.
Resting Potential: Is the state of a neuron prior to the sending of a nerve impulse. The membrane maintains an electrical polarization. Sodium is on the outside, and potassium is on the inside.
Action Potential: Refers to the rapid depolarization of the neuron. When the neuron is stimulated, an impulse will begin, and the sodium will rush in, turning the inside positive.
The amplitude and velocity of an action potential are independent of the intensity of the stimulus. This is known as the all or none response
