Your spinal cord is the long, cylindrical structure that connects your brain and lower back. The Publishers assumes no responsibility for errors,. It is a relatively small bundle of tissue (weighing 35g and just about 1cm in diameter) but is crucial in facilitating our daily activities. Cerebellum: Located in the back of the brain, it controls basic movement, balance, and even posture. The brain is about 60 percent fat. The nerve roots that exit the spinal cord/spinal canal branch out into the body to form the Peripheral Nervous System (PNS). A cross-section of the spinal cord looks like a white oval containing a gray butterfly-shape, as illustrated in Figure 1. Spinal Cord Injury: Levels, Treatment, Symptoms, Recovery. It runs down from the brain through a canal in the center of the bones of the spine. Symptoms vary but might include pain, numbness, loss of sensation and muscle weakness. The PNS is divided into two sections: the Autonomic Nervous System (ANS) and the Somatic Nervous System (SNS). Gray matter contains neural cells, dendrites, and axon terminals, while white matter consists of axons and myelin, and plays a key role in nerve cells' ability to connect to one another. The somatic nervous system is made up of neurons connecting the CNS with the parts of the body that interact with the outside world. This may require the placement of a breathing tube and use of a ventilator. Most spinal cord injuries come from a sudden, traumatic blow to the vertebrae.
