The nervous system plays a role in nearly every aspect of our health and well-being. It monitors and regulates the functions of the body. An injury at C4 or higher will affect the diaphragm, the muscle that moves the lungs for breathing. The central nervous system (CNS) consists of the brain and the spinal cord. Usually, the size of nerve cells varies depending on how long the electrical impulses are to be transmitted. The brain processes and interprets sensory information sent from the spinal cord. Your spinal cord helps carry electrical nerve signals throughout your body. Spinal nerves can be impacted by a variety of medical conditions, resulting in pain, weakness, or decreased sensation. At the level of the tragus, the ATN lies deep to the STA; it then moves superficially to lie superficial to the STA at the level of the zygomatic arch.
