KROK 1 2016 – Question 41 · KROK (Medicine) · Human Anatomy
After a traffic accident a 36-year-old patient has developed muscle paralysis of the extremities on the right, lost pain and thermal sensitivity on the left, and partially lost tactile sensitivity on both sides. What part of the brain is the most likely to be damaged?
- A. Posterior horn of the spinal cord
- B. Left-hand side of the spinal cord
- C. Right-hand side of the spinal cord
- D. Anterior horn of the spinal cord
- E. Motor cortex on the left
Hint
Ask where the motor and the pain-temperature pathways cross relative to a lesion, and what a one-sided lesion would therefore do on each side of the body.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
