A Case of Spinal Cord Injury
Jason is a 21 year old senior at the University of South Africa, majoring in economics. While on spring
break in Johannesburg, Jason was involved in a motorcycle accident. In the accident he was thrown from
his pike to the pavement, landing on his back. A police officer witnessed the accident and immediately
called for medical assistance. Emergency personnel arrived within minutes, and upon recognizing the
seriousness of Jason's back injury, immobilized his neck and secured him to a rigid board prior to
transporting 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. Upon
examination by the emergency room personnel, Jason was found to have numerous abrasions and
contusions, and loss of both sensation and motor control of his legs. After he was stabilized, a complete
neurological exam was performed to assess and localize Jason's injury. The neurological exam…
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?

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. 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.

- Ted is a war veteran who was hit in the back with small pieces of shrapnel. His skin is numb in the center of his buttocks and along the entire posterior side of a lower limb, but there is no motor problem. Indicate which of the following choices is the most likely site of his nerve injury, and explain your choice: (a) a few dorsal roots of the cauda equina, (b) spinal cord transection at C6, (c) spinal cord transection at L5, (d) femoral nerve transected in the lumbar region.arrow_forwardXena eventually catches Callisto (remember, she is 25 years old). Salmoneus, who is 60 years old, agrees to deliver Callisto to face charges for war crimes. On the way, their cart crashes down a ravine. Salmoneus also suffers damage to his spinal cord during the accident. Compare the likely degree of regeneration/recovery of his spinal cord with that of the injured skeletal muscles and describe the consequences of your observations for his quality of life and ability to remain active.arrow_forwardWhy would a spinal injury in the cervical region result in more extensive deficits in motor and sensory function than a spinal injury in the lumbar region?arrow_forward
