Without our nerves, we couldn’t live. Nerves act like the body’s electrical wiring and connect the brain to every part of the body. They allow us to move and feel sensations. They even protect the body by transmitting pain. Some nerves control vital functions which take place within the body such as the heartbeat, digestion, breathing, swallowing and perspiration.
The nervous system is categorized into two: the central nervous system, which connects the brain to the spinal cord, muscles and internal organs; and the peripheral nervous system, which consists of nerves that extend to every part of the body, right to the end of your fingers and toes.
If you ever feel tingling or numbness in your hands or feet, you may have nerve problems. When the nerves become damaged, they are no longer communicating well with the parts they are connected to. Medically, this is known as neuropathy. The most commonly affected parts are the hands and feet which have long nerves that may not get sufficient nutrients and therefore carry a higher risk of neuropathy.
