NEET PG DENTAL EXAM

Detailed explanation-1: -An action potential is a rapid sequence of changes in the voltage across a membrane. The membrane voltage, or potential, is determined at any time by the relative ratio of ions, extracellular to intracellular, and the permeability of each ion.

Detailed explanation-2: -Neurons conduct electrical impulses by using the Action Potential. This phenomenon is generated through the flow of positively charged ions across the neuronal membrane.

Detailed explanation-3: -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-4: -Propagation of action potential An action potential is generated in the body of the neuron and propagated through its axon. Propagation doesn’t decrease or affect the quality of the action potential in any way, so that the target tissue gets the same impulse no matter how far they are from neuronal body.
