ANATOMY

Detailed explanation-1: -The nervous system uses tiny cells called neurons (NEW-ronz) to send messages back and forth from the brain, through the spinal cord, to the nerves throughout the body. Billions of neurons work together to create a communication network.

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.

Detailed explanation-3: -The transfer of information from neuron to neuron takes place through the release of chemical substances into the space between the axon and the dendrites. These chemicals are called neurotransmitters, and the process is called neurotransmission. The space between the axon and the dendrites is called the synapse.

Detailed explanation-4: -Neurons carry messages from the brain via the spinal cord. The neurons that carry these messages to the muscles are called motor neurons.

Detailed explanation-5: -Motor neurons tell your muscles to move. Sensory neurons take information from your senses and send signals to your brain.
