The type of channel found at the axon hillock

WebThe axon hillock is the area formed from the cell body of the neuron as it extends to become the axon. It precedes the initial segment. The received action potentials that are summed in the neuron are transmitted to the axon hillock for the generation of an action potential from the initial segment. Axonal initial segment WebB)The brief refractory period prevents reopening of voltage-gated Na+ channels. C)The axon hillock has a higher membrane potential than the terminals of theaxon. D)Ions can flow along the axon in only one direction. E)Voltage-gated channels for both Na+ and K+ open in only one direction.
