Detailed explanation-1: -What does the nervous system do? 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: -Messages, in the form of electrical impulses, constantly travel back and forth between the brain and other parts of the body. A special cell called a neuron is responsible for carrying these messages. There are about 100 billion neurons in the human brain.
Detailed explanation-3: -Think about catching a ball: your brain tells a neuron to send an electrical signal to the neuromuscular junction synapse, and this causes neurotransmitter to be released onto your finger muscles, so that they contract to catch the ball.
