Posterior Perspective of the Spinal Cord of a Transparent Male

Description

Posteriorly, the cervical portion of the spinal cord (myelon) lies centrally within the vertebral canal, aligned with the stacked cervical vertebrae of the vertebral column. A distinct posterior median sulcus tracks in the midline, separating the right and left posterior funiculi, while paired dorsal rootlets converge toward the dorsal roots of the cervical spinal nerves. Each nerve courses laterally through its corresponding intervertebral foramen between adjacent vertebrae, then begins to branch toward the neck and shoulder girdle. Midline symmetry stands out. This posterior perspective matters when you need to teach or plan around the dorsal elements: dorsal roots carry sensory afferents, and their proximity to the laminae and spinous processes frames common posterior approaches to the cervical spine. It also offers a clean way to discuss cervical radiculopathy from foraminal stenosis or posterolateral disc-osteophyte complexes, which typically compress a cervical nerve root at or near the foramen rather than the cord itself. The relationship between the sulcus, posterior columns, and exiting roots provides a practical map for correlating dermatomal symptoms with level. Use this artwork for neuroanatomy and gross anatomy teaching on spinal cord surface landmarks, for spine surgery texts describing posterior decompression and foraminotomy, or for patient-facing education explaining why neck pathology can refer pain or paresthesia into the upper limb. It also suits radiology and neurology materials that pair anatomical drawings with axial MRI or CT myelography at cervical levels to orient readers to dorsal versus ventral compartments.
