GlossaryNerves

bundles of fibers transmitting electrical signals in the body

Nerves are bundles of fibers that transmit electrical signals between the brain, spinal cord, and other parts of the body. They play a crucial role in controlling bodily functions, including movement, sensation, and reflexes. For example, sensory nerves carry information from the skin to the brain, while motor nerves send signals from the brain to muscles, enabling movement.
