Anatomy 3

A 47-year-old man presents to the emergency room with complaints of progressively worsening shoulder pain and weakness over the past 3 weeks. He works as a grocery store stocker and reports that lifting heavy objects and breathing in seem to exacerbate the pain. On physical examination, the patient's right eyelid appears slightly lower compared to the left. Further inspection of the eyes reveals a smaller right pupil, in addition to flushed, dry skin on the right half of his face. Lungs bases are clear to auscultation, but the right apex is dull to percussion. S1 and S2 hearts sounds are normal. Chest X-ray reveals a unilateral consolidation at the apex of the right lung.

If this patient’s lesion is in the cervical spinal cord, at which of the following levels would the lesion be expected?

  • A) C2-C5
  • B) C4-C7
  • C) C8-T1
  • D) T2-T4
  • E) T4-T5
