WebThe membrane potential has to reach a certain threshold for firing; this is known as summation (for which there are spatial and temporal components) and occurs at the axon hillock. Certain populations of neurons only express receptors for certain neurotransmitters.

WebNeurons are usually described as having one, and only one, axon—a fiber that emerges from the cell body and projects to target cells. That single axon can branch repeatedly to communicate with many target cells. It is the axon that propagates the nerve impulse, which is communicated to one or more cells. earl\u0027s breakdown tabWebFinally, when the signal reaches the end of the axon or axon terminal, it results in the release of a chemical signal known as a neurotransmitter.
