WebJun 12, 2024 · Anatomy definition: Axon hillock is the neuronal projection that transmits the neuronal signals from the neuronal cell body to different body cells (Note: axons carry outward-bound signals) while the dendrites are the root-like projections that receive the signals from the other cells of the body and relay them to the nervous system (Note: … WebScience. Biology. Biology questions and answers. 7. The Action Potential is Propagated Along the Axon • After an action potential is generated at the axon hillock, it is propagated down the axon. • Positive charge flows along the axon, depolarizing adjacent areas of membrane, which reach threshold and generate an action potential.

WebThe axon arises from the cell body at a specialized area called the axon hillock. Finally, many axons are covered with a special insulating substance called myelin , which helps them convey the nerve impulse rapidly.
