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.

3) Lucas is a 40-year old man who sustained a Spinal Cord Injury (SCI) in a snow skiing accident 10 years ago. The level of his injury is at C6 – he preserved function below that neurologic level. He cannot walk and he also has some impairment in the arms and hands. He is still able to use a manual wheelchair with his upper limbs’ ability. Lucas is interested in the HandbikeBattle coming up in 2024. This organized event boosts self-confidence and fitness in those who have completed rehabilitation after an injury. Lucas wishes to train this year so that he can think of going to that event. Lucas may need a power-assisted handcycle for the event, but will train with you to be properly prepared. He has not been as active in the past 5 years as he dedicated himself to his work and family and his recovery in rehab. He has a handcycle and a roller as shown below and you have agreed to meet with him to ensure he is performing safely and correctly during his weekly sessions. a) What…
Spinal Cord It had been a busy week for Amanda. She had taken three exams, and as if that wasn't stressful enough, her sister was ill and Amanda had to spend much of her time helping out at home. By the end of the week, Amanda decided to go to the beach for a walk and some genuine relaxation. The day was warm and Amanda took off her shoes so she could walk barefoot and feel the sand between her toes. Halfway down the beach, she stepped on something extremely sharp and withdrew her foot in pain. As Amanda hopped around the sand on one foot, rubbing the other to ease the pain, she decided to put her shoes back on. What type of reflex is responsible for the uninjured leg going into full extension so she can balance on one foot?

Regarding the reflex that moved her injured foot, classify it according to the complexity of the circuit.

As Amanda hopped around the sand on one foot, rubbing the other to ease the pain, she decided to put her shoes back on. As Amanda stepped on something sharp, she withdrew her foot due to reflexes. Any pain experienced would have been just AFTER she moved her foot off of the sharp object. Why is there a delay in perceiving the pain sensation?
