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 is at the end of the cell body and it controls the firing of the neuron. If the graded potential is enough to meet the threshold, it will depolarise the membrane and an action potential will travel the length of the axon.
