Textbook Question
Chapter 13, Problem 2TYC
Wallace is the victim of a hunting accident. A bullet grazed his vertebral column, and bone fragments severed the left half of his spinal cord at segments T8 through T10. Since the accident, Wallace has had a condition called dissociated sensory loss, in which he feels no sensations of deep touch or limb position on the left side of his body below the injury, and no sensations of pain 01 heat from the right side Explain what spinal tract(s) the injury has affected and why these sensory losses are on opposite sides of the body.

Wallace is the victim of a hunting accident. A bullet grazed his vertebral column, and bone fragments severed the left half of his spinal cord at segments T8 through T10. Since the accident, Wallace has had a conditioncalled dissociated sensory loss, in which he feels no sensations of deep touch or limb position on the left side of his body below the injury, and no sensations of pain or heat from the right side. Explain what spinal tract(s) the injury has affected and why these sensory losses are on opposite sides of the body.
As with most spinal nerves, the sacral spinal nerves become part of a nerve plexus, the sacral plexus. What is a nerve plexus?
dermatome maps explain sensory supply, and this patient did not have any motor problems. So which root(s) of nerves were affected, dorsal or ventral? Explain your answer.
Two patients are admitted to the hospital. According to their charts,both have herniated disks that are placing pressure on the roots of thesciatic nerve. One patient has pain in the buttocks and the posterioraspect of the thigh. The other patient experiences pain in the posteriorand lateral aspects of the leg and the lateral part of the ankle and foot.Explain how the same condition, a herniated disk, can produce suchdifferent symptoms.

In the background section the authors wrote “Neurodegenerative disease are progressive conditions that occur through impairment in the function or structure of neurons in the peripheral nervous system or brain [1].’ Based on this quote, is the “or brain” statement synonymous with the peripheral nervous system or is the “or brain” statement in addition to the peripheral nervous system? The nerves outside of the brain and spinal cord are part of the peripheral nervous system. The main function of the peripheral nervous system is to transmit signals from the brain and spinal cord to the rest of the body making the "or brain" statement synonymous. How do you know that your answer to question 1 is correct?arrow_forward
