Detailed explanation-1: -Believed in the past to be simple “helpers” of neurons, astrocytes have revealed over time cells that play a much more active role in the brain (Gomez-Gonzalo et al., 2010).
Detailed explanation-2: -Thus, the correct answer is ‘Cell body-Axon-Nerve terminal’.
Detailed explanation-3: -Correct answer: An action potential is a very brief shift or spike in a neuron’s electrical charge that sends a message down the axon. An action potential is the can be described as a neuron “firing.” Action potentials occur after the resting potential and before a refractory period.
Detailed explanation-4: -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.
