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: -When neurons communicate, the neurotransmitters from one neuron are released, cross the synapse, and attach themselves to special molecules in the next neuron called receptors. Receptors receive and process the message, then send it on to the next neuron. 4. Eventually, the message reaches the brain.
