ANATOMY

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 spinal cord carries messages back and forth between the brain and the nerves that run throughout the body.

Detailed explanation-3: -Afferent neurons carry signals towards the CNS – afferent means “towards”. They provide information about the external environment and the regulatory functions being carried out by the nervous system. An afferent neuron has a receptor at its ending that generates action potentials in response to a particular stimulus.
