Learn more about the human body nerve cells using these free and printable nerve cell diagrams. The nerve cells are specialized cells, which transmits message from one part to another part of the body. All cellular organisms have evolved a coordinating system by which messages can be received and transmitted very rapidly to organs, enabling them to respond to an environmental change. The system which is responsible for this process is called as nervous system. The functional units of nervous system are nerve cell. If you want to know further about the nerve cell, take a look at the following diagram.
The nerve cell diagram posted above contains the detail illustration of the anatomy or structure of nerve cell. Many nerve cells are of the basic type illustrated above. Some kind of stimulus triggers an electric discharge of the cell which is analogous to the discharge of a capacitor. This produces an electrical pulse on the order of 50-70 millivolts called an action potential. The electrical impulse propagates down the fiber-like extension of the nerve cell (the axon). An axon is a long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses away from the neuron’s cell body. Axons are also known as nerve fibers. The function of the axon is to transmit information to different neurons, muscles and glands.
In the diagrams above, we provide you with the nerve cell diagram of human and animal. In animal nerve cell, nervous coordination is the function of the nervous system. In human cell, the cell body contains the necessary structures for keeping the neuron functional. That includes the nucleus, mitochondria, and other organelles. There are many functions of nerve cell, such as for communication and coordination, sensory nerves, which carries the message to brain. It also allows people to react to a stimulus because they conduct electrical impulses away from the neuron’s cell body.
