NEET PG DENTAL EXAM

Detailed explanation-1: -Thus, the results suggested that action potentials initiate in the axon at some distance from the soma and that the local density of Na+ channels in the axon hillock/initial segment, which is not high, does not determine the lowest threshold of the neuron for action-potential initiation.

Detailed explanation-2: -The axon hillock is the region of a neuron that controls the initiation of an electrical impulse based on the inputs from other neurons or the environment. The electrical part of the electrochemical signal is called an action potential. Action potentials are all or none electrical signals.
