AP PSYCHOLOGY

Detailed explanation-1: -As an action potential (nerve impulse) travels down an axon there is a change in electric polarity across the membrane of the axon. In response to a signal from another neuron, sodium-(Na+) and potassium-(K+)–gated ion channels open and close as the membrane reaches its threshold potential.

Detailed explanation-2: -The conduction of the nerve impulse down the axon is called as action potential. The nerve impulse is the form of electrical signals produced from the dendrites that get moves down the axon of the nerve cell to communicate with nearby neuron cell.

Detailed explanation-3: -An action potential, also called a nerve impulse, is an electrical charge that travels along the membrane of a neuron.

Detailed explanation-4: -Conduction of Nerve Impulse. A nerve impulse is the electric signals that pass along the dendrites to generate a nerve impulse or an action potential. An action potential is due to the movement of ions in and out of the cell. It specifically involves sodium and potassium ions.

Detailed explanation-5: -An action potential occurs when a neuron sends information down an axon, away from the cell body. Neuroscientists use other words, such as a “spike” or an “impulse” for the action potential. The action potential is an explosion of electrical activity that is created by a depolarizing current.
