MEDICAL PHYSIOLOGY

Detailed explanation-1: -Action potential – Brief ( 1 ms) electrical event typically generated in the axon that signals the neuron as ‘active’. An action potential travels the length of the axon and causes release of neurotransmitter into the synapse.

Detailed explanation-2: -The action potential is an explosion of electrical activity that is created by a depolarizing current. This means that some event (a stimulus) causes the resting potential to move toward 0 mV. When the depolarization reaches about-55 mV a neuron will fire an action potential.

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: -Neurons communicate via both electrical signals and chemical signals. The electrical signals are action potentials, which transmit the information from one of a neuron to the other; the chemical signals are neurotransmitters, which transmit the information from one neuron to the next.
