**Clinical Scenario: Neurological Examination and Spinal Cord Injury**An 18-year-old male is shot in the back and is taken to the emergency room. A neurological exam reveals a hemisection of the right half of the spinal cord extending from T8 to T12.**Question:**Which of the following deficits will most likely result from this injury?**Options:**- Loss of pain and temperature sensation from the left arm and leg; loss of conscious proprioception from the right arm and leg; extreme weakness of right arm and leg- Loss of pain and temperature sensation from the right leg; loss of conscious proprioception from the left leg; extreme weakness of left leg- Loss of pain and temperature sensation from the left leg; loss of conscious proprioception from the right leg; extreme weakness of right leg- Loss of pain and temperature sensation from the right arm; loss of conscious proprioception from the left arm; extreme weakness of left arm- Loss of pain and temperature sensation from the left arm; loss of conscious proprioception from the right arm; extreme weakness of right arm**Explanation:**This scenario describes an injury consistent with Brown-Séquard syndrome, where a hemisection (partial cutting) of the spinal cord leads to a characteristic pattern of neurological deficits.

A 67-year-old male patient arrives in the emergency department complaining of progressively worsening bouts of right leg weakness. His wife notes that he is confused and often has trouble forming words at these times, which typically last about a day. The right leg weakness improves only slightly from instance to instance, leaving him weaker each time. Because the symptoms are transient, he has put off seeing a physician until now. His wife is worried that he might be having a stroke. He reports having smoked a pack of cigarettes each day for 45 years. • What surgical procedure will be scheduled? • What tests might the ED physician order to arrive at a diagnosis? • What are the possible diagnoses, and which is most likely?
Which statement is NOT true with respect to a posterior root of the spinal cord? O Is considered sensory O Is considered afferent Cell bodies are housed outside the spinal cord Can contain somatic and/or autonomic information O Cell bodies are housed inside the spinal cord
A 21-year-old male medical student is taken to the ER by his roommates complaining of progressive weakness. The history reveals that this student had an intestinal virus with diarrhea and vomiting that resolve over 2 days. About 10 days later, he noticed tingling sensations and numbness in his feet, followed by progressive weakness. Over the last 8 days it has gotten so bad that he is having trouble standing, and walking. His physical examination shows normal cranial nerves, distal weakness of the lower extremities (about 3+/5), absent reflexes over the lower extremities, and mild decreased vibration and position sense loss. 1. What is your differential diagnosis? 2. Where is the lesion? 3. Which diagnostic test would you perform first and why? 4. What is the most likely diagnosis and why?

Median nerve: show how it branches from the brachial plexus, travels deep to the clavicle, distally down the anterior brachial and antebrachial regions, and eventually passes through the flexor retinaculum to innervate the wrist flexor muscles. Obturator nerve: show how it branches from the lumbar plexus through the obturator foramen to innervate the muscles of the medial thigh, i.e., gracilis and adductors. Sciatic nerve: show how it branches laterally from the sacral plexus at the intervertebral foramen between L5 and S1 and then pass through the greater sciatic notch to the posterior thigh to innervate the hamstrings. Show anterior and posterior image that show the plexus from which the nerve is derived, its pathway though the body, and to the anatomical area where it innervates skeletal muscles. Show either by drawing or using a skeleton model.
