WebSynaptic transmission is the process by which one neuron communicates with another. Information is passed down the axon of the neuron as an electrical impulse known as … WebThe action potential is unidirectional. It will go from the hillock (area where the axon starts) to the terminus (end of the axon near the synapse) in a wave like manner. He was saying that the reason for this is because the membrane is hyper polarized for a while after the action potential has past (more negative then the resting potential). rsv is it contagious for adults

Information is passed down the axon of the neuron as an electrical impulse known as action potential. Once the action potential reaches the end of the axon it needs to be transferred to another neuron or tissue.

Webaction potential (AP) the change in electric potential that propagates along the axon of a neuron during the transmission of a nerve impulse or the contraction of a muscle. It is marked by a rapid, transient depolarization of the cell’s plasma membrane, from a resting … WebAction potential is simply a transient change in resting membrane potential. When a stimulus acts on a cell, it changes the permeability of the membrane in such a way that …
