A nerve cell is called a neuron. Nerves cells make up your nervous system. Your nervous system is your body’s communication command center. It sends and receives communication from all parts of your body and reacts to changes inside and outside of your body. Each nerve cell has three sections. The sections of a nerve cell can be thought of like a tree. The soma, or cell body, is like the tree’s root system. The roots of the soma, called dendrites, receive the “nutrients” from the soil. The “nutrients” in this case are the chemical messages they receive from other nearby nerve cells. These messages are converted into electric impulses. The soma also contains the cell’s nucleus. The axon is like the tree’s long trunk. The nutrients are transported from the tree’s roots up through the tree’s trunk. Similarly, the axon transports the impulses from the soma onward along its path. The axon terminal is like the tree buds at the end of the tree’s branches. Leaves and pollen come out of these buds. The electrical impulses are sent (or “released” like pollen from a bud) to be picked up by the next nerve cell. This process keeps repeating as the impulse or message continues in its travels within your brain and spinal cord or out to your body. The result might be muscle fibers contracting to move your arm, help you breathe or keep your heart beating.
