Why does initiation of nerve impulse occurs at the axon hillock?
In motor neurons, the poion of the cell with the lowest threshold for the production of a full fledged action potential is the initial segment, the poion of the axon at and just beyond the axon hillock. Ref: Ganong's Review of Medical Physiology, 23rd Edition, Chapter 4.
It is unmyelinated
Due to the release of neurotransmitter
It has a lower threshold than the rest of the axon
None of the above
