The human brain is made up of many different cortexes, and each cortex is associated with the different functions of the body. The cerebral cortex is the primary area of the nervous system. This is where our conscious mind is found. This area allows us to be aware of ourselves and our sensations, which includes communication, memory, comprehension and to be able to initiate voluntary movement. The cerebral cortex has three kids of areas, the motor area, the sensory area and the association area. Each hemisphere is associated with the opposite side of the body. For example the left hemisphere is associated with the right side of the body, and vice versa for the left side of the body. The motor functions are mapped into functions in an upside
If damage to a nerve is severe or close to the cell body the entire neuron may die as well as other neurons that are normally stimulated by that particular nerve, may die as well. However if the cell body remains intact, cut or compressed the axons of the peripheral nerves can regenerate. However post trauma axon regrowth never exactly matches what existed before the injury, and a lot of the recovery involves retraining the nervous system to respond appropriately so that stimulus and response are coordinated.

Now that I understand what nerves connect with what areas of the brain and spinal cord, this will help me to make an educated decision of what area I need to X-ray on the patient. For example if a patient comes in and complains of pain in their leg with tingling sensation, I will need to use some sort of digital image technology to see what might be going on with their spine. It could turn out to my transverse myelitis, which is inflammation of the spinal cord, or it could turn out to be sciatica. This knowledge will help me make and educated decision with my patient’s symptoms, and help diagnose them, and help educate the patient on how to get well, or deal with the issue that has come
