1. Describe the functional anatomy of the spinal cord using the following terms: white matter, gray matter, tracts, roots, and spinal nerves. * White matter is one of the two components of the central nervous system, and it consists of glial cells and myelinated axons that transmit signals from one region of the cerebrum to another as well as in between the cerebrum and lower brain centers. Grey matter contains neural cell bodies. Unlike white matter, it is mostly made up of myelinated axon tracts. Tracts are bundles of fibers that connect to different parts of the CNS. Roots receive information sent by neurons. Spinal nerves refer to a mixture of spinal nerves, which carry

Myotomes are spinal nerve fibers and the corresponding muscles. When a spinal cord injury happens, myotomes can be damaged which result in the lack of movement in a muscle and the abnormal functioning of dermatomes can pinpoint spinal nerve damage because lack of sensation occurs.

6. Define the term stretch reflex and describe how stretch reflexes are used to anatomically localize SCI. * A stretch reflex is a contraction of a muscle when an attached tendon is pulled. Stretch reflexes are important in maintaining proper posture. Stretch reflexes are used to determine which areas of the body the central nervous system are not responding to. For example, if you tap your knee to check for reflex and the leg doesn’t move, you then know that the peripheral nerves that lead to the knee are nonresponsive and/or the brain is not receiving a signal from that particular area.

7. Based upon the results of Jason’s neurological exam, what is the neurological level of his SCI * Jason is experiencing a complete SCI with no movement of anything below his groin. The neurological level stops at the thoracic cord.
