Nerve function is essential for communication within the body. Nerves are made up of specialized cells called neurons, which transmit signals between the brain, spinal cord, and other parts of the body. These signals can be electrical or chemical, allowing us to react to our environment, feel sensations, and control our movements. When a nerve is stimulated, it generates an electrical impulse that travels along its length. This impulse can then trigger the release of neurotransmitters, which are chemicals that help transmit the signal to the next neuron or target tissue. This intricate process enables our bodies to function smoothly and respond to various stimuli.
