In most neurons, the axon hillock has the lowest threshold to produce an action potential because:

Question

Accepted Answer

it has the highest density of voltage-gated Na+ channels.

Answer

it acts as a current sink for EPSPs occurring at the dendrites.

Answer

it is the region which is closest to the nerve terminal.

Answer

the voltage-gated Na +  channels in this region do not become refractory.

Answer

the voltage-gated Na +  channels in this region possess the ability to adapt to a maintained pre-synaptic input.
