Detailed explanation-1: -Your nervous system uses specialized cells called neurons to send signals, or messages, all over your body. These electrical signals travel between your brain, skin, organs, glands and muscles. The messages help you move your limbs and feel sensations, such as pain.
Detailed explanation-2: -The somatic nervous system One of its roles is to relay information from the eyes, ears, skin and muscle to the central nervous system (brain and spinal cord). It also obeys commands from the central nervous system and makes muscles contract or relax, allowing us to move.
Detailed explanation-3: -In our brain and bodies, neurons communicate with each other by sending messages using a form of electricity. In neurons, this electricity is created by the flow of charged particles called ions that move across the outer membrane of the cell [1].
