By: Dalton Penland
The Nervous system is made up of the Brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body
Some Threats to the Nervous system
Trauma.
Infections.
Degeneration.
Structural defects.
Tumors.
Blood flow disruption.
Autoimmune disorders.
Trauma affects the Nervous System by pushing the nervous system outside its ability to regulate itself. For some, the system gets stuck in the “on” position, and the person is overstimulated and unable to calm. Anxiety, anger, restlessness, panic, and hyperactivity can all result when you stay in this ready-to-react mode.
As the tumor grows, it creates pressure on and changes the function of surrounding brain tissue, which causes signs and symptoms such as headaches, nausea and balance problems. A brain tumor is a mass or growth of abnormal cells in your brain.
