The document contains 15 questions about the anatomy and morphology of the spinal cord, including its external and internal structures at different levels, blood supply, spinal nerve plexuses, dermatomes, myotomes and sclerotomes, epidural space and anesthesia, lumbar puncture, dorsal root ganglion, sensory ganglia, supportive non-neuronal cells, factors fixing its position, venous drainage, meningeal coverings, ascending and descending tracts in the cervical region. The questions require detailed explanations and examples or diagrams for some responses.
