In this video, I cover the exterior of the spinal cord. I discuss how sensory and motor information is carried to and from the cord via dorsal and ventral roots, respectively. I also explain how these roots come together to form spinal nerves, and how a pair of spinal nerves leaves at each segment of the cord; these segments are classified as belonging to cervical, thoracic, lumbar, sacral, or coccygeal regions. Then I describe some major landmarks of the cord, including the conus medullaris, cauda equina, lumbar cistern, and filum terminale.
