The axon hillock is situated between the cell body and the axon. Electrical impulses from the dendrites and cell body are summed at this point, which then can send an action potential down the axon. The body of a neuron has dendrites sticking out of all sides. On one end, it has a long tail, called an axon, which ends in the terminal buttons.

To inject a guided mode in the myelin sheath and verify its guidance, one might need to decapitate the axon near the terminal and hillock regions, couple the
