PATHOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -After initiation, action potentials travel down axons to cause release of neurotransmitter. 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-3: -During the Action Potential Once the cell reaches a certain threshold, an action potential will fire, sending the electrical signal down the axon. The sodium channels play a role in generating the action potential in excitable cells and activating a transmission along the axon.
