Homonym: nerve (Courage)
Nerve refers to a bundle of fibers that transmit electrical signals between the brain and different parts of the body. These fibers are part of the nervous system, which controls various functions, including movement, sensation, and reflexes. Nerves can be classified into sensory nerves, which carry information from the body to the brain, and motor nerves, which send signals from the brain to muscles.
Nerves are made up of specialized cells called neurons. Each neuron consists of a cell body, dendrites, and an axon. The axon is responsible for transmitting signals to other neurons or muscles, allowing for communication throughout the body. Proper nerve function is essential for overall health and well-being.
