Please answer all questions. Thank you for you everything! A Case of Spinal Cord InjuryJason is a 21 year old senior at the University of South Africa, majoring in economics. While on springbreak in Johannesburg, Jason was involved in a motorcycle accident. In the accident he was thrown fromhis pike to the pavement, landing on his back. A police officer witnessed the accident and immediatelycalled for medical assistance. Emergency personnel arrived within minutes, and upon recognizing theseriousness of Jason's back injury, immobilized his neck and secured him to a rigid board prior totransporting him to the emergency room of the nearest hospital.When he arrived at the hospital, Jason was conscious and complained of pain in his lower back. Uponexamination by the emergency room personnel, Jason was found to have numerous abrasions andcontusions, and loss of both sensation and motor control of his legs. After he was stabilized, a completeneurological exam was performed to assess and localize Jason's injury. The neurological exam revealedthe following:Jason demonstrated normal or near normal strength in flexing and extending his elbows, extending hiswrists, and when flexing his middle finger and abducting his little finger on both hands. However, heexhibited no movement when medical personnel tested his ability to flex his hips, extend his knees, anddorsiflex his ankles. Stretch reflexes involving the biceps, brachioradialis, and triceps muscles werefound to be normal, while those involving the patella and ankle were absent. In addition, Jason Wasfound to have normal sensitivity to pin prick and light touch in areas of his body above the level of hisinguinal (groin) region, but not below that region of the body.Questions1. Describe the functional anatomy of the spinal cord using the following terms: white matter, graymatter, tracts, roots and spinal nerves.2. Define the terms reflex and spinal reflex and identify the components of a reflex arc.3. Define the term spinal cord injury (SCI) and state its prevalence.4. Define the terms neurological level, tetra(qudri)plegia, and paraplegia.5. Define the terms dermatome and myotoma and explain how each relates to SCI.6. Define the term stretch reflex and describe how such reflexes are used to anatomically localizeSCI.7. Based upon the results of Jason's neurological exam, what is the neurological level of his SCI?8. Discuss the management of SCI and the factors that determine the prognosis for this condition.
