AP PSYCHOLOGY

Detailed explanation-1: -When a neuron is sufficiently stimulated to reach the neural threshold (a level of stimulation below which the cell does not fire), depolarization, or a change in cell potential, occurs. Potentials. The term potential refers to a difference in electrical charges.

Detailed explanation-2: -The action potential is said to be all-or-nothing because it occurs only for sufficiently large depolarizing stimuli, and because its form is largely independent of the stimulus for suprathreshold stimuli.

Detailed explanation-3: -Dendrite – The receiving part of the neuron. Dendrites receive synaptic inputs from axons, with the sum total of dendritic inputs determining whether the neuron will fire an action potential.

Detailed explanation-4: -The all-or-none law is a principle that states that the strength of a response of a nerve cell or muscle fiber is not dependent upon the strength of the stimulus. If a stimulus is above a certain threshold, a nerve or muscle fiber will fire.
