In the process of beginning an action potential,the threshold refers to

A) neuron extensions that conduct messages toward the cell body.
B) a minimum intensity of excitatory minus inhibitory stimulation.
C) neuron extensions that send messages to other neurons.
D) the junction between a sending and receiving neuron.

Action Potential

A temporary reversal in the electrical polarization of the membrane of a nerve cell or muscle cell, allowing for the transmission of signals.

Threshold

The minimum level of stimulus intensity required to activate a sensory system or produce a response in a physiological or psychological system.

Inhibitory Stimulation

A neural process that decreases the likelihood of a neuron firing, thereby reducing or preventing certain neural activities.
