The rod went into his back around the level of T9 but was removed before arrival. He has no past medical history and does not take any medications. On physical examination, he has significant muscle weakness in his entire left lower body. He also exhibits impaired vibration and proprioception in his left leg as well as loss of pain and temperature sensation in his right leg. Which of the following sections of the spinal cord was most likely damaged in this patient?? A: Anterior cord, B: Central cord, C: Left hemicord, D: Posterior cord, E: Right hemicord,  <response>: Based on the description in the question stem, the patient has a spinal cord injury likely around the T9 level. He has weakness on the left lower body, which indicates damage to the lateral corticospinal tract that carries motor signals. He also has sensory loss on the right leg but not the left, indicating the spinothalamic tract that carries paintemperature sensation is damaged on the right side. Finally, he has proprioception and vibration impairment on the left leg, suggesting damage to the posterior columns. This pattern of deficits localizes the injury to the left lateral cord of the spinal cord, which contains the lateral corticospinal tract and the left spinothalamic tract. C: Left hemicord
