Nerve fibers are the long extensions of neurons that transmit electrical impulses throughout the nervous system, playing a crucial role in communication between different parts of the body. They are primarily classified into myelinated and unmyelinated fibers, which influence the speed and efficiency of signal transmission.

Electrical impulses are rapid signals transmitted along the nerve fibers, enabling communication between neurons and other cells. They are crucial for the functioning of the nervous system, facilitating responses to stimuli and coordination of bodily functions.

The nervous system is a complex network of neurons and supporting cells that transmits signals throughout the body, enabling coordination of actions and sensory information. It is divided into the central nervous system, which includes the brain and spinal cord, and the peripheral nervous system, which connects the rest of the body to the central nervous system.
