Nerve that affects the little finger side of the arm and palm or the hand, with its branches.
Making the world better, one answer at a time. An axon hillock is a special cell body that connects an axon to a neuron. It is the last place where propagated membrane potentials are transmitted to the axon. An axon hillock is a special cell body that connects an axon to a neuron.

The axon hillock, because of its configuration of voltage-gated ion channels, is most sensitive to causing APs. EPSPs from dendrites, the soma, the hillock, if they can all push the membrane voltage above threshold together, will ignite a spike. The AP typically runs down the axon towards its synapses.
