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. It is the last place where propagated membrane potentials are transmitted to the axon.
The axon hillock has a number of specialized properties that make it capable of action potential generation, including adjacency to the axon and a much higher density of voltage-gated ion channels than is found in the rest of the cell body.or many years, it had been believed that the axon hillock was the usual site of action potential initiation. It is now thought that the earliest site of action potential initiation is found just adjacent, in the initial (unmyelinated) segment of the axon.
