The axon hillock is a specialized part of the cell body (or soma) of a neuron that connects to the axon. It is the last site in the soma where membrane potentials propagated from synaptic inputs are summated before being transmitted to the axon. This is where the decision to create an action potential or not is made. This area is characterized by having a high number of voltage-gated sodium channels, which are necessary for the initiation of action potentials.
