Spinal Cord, Gross Anatomy

Description

Sagittal section through an adult female body frames the central nervous system from the cranial cavity into the vertebral canal. The cerebral hemispheres are rendered with clear gyri and sulci, tapering inferiorly to the brainstem at the level of the foramen magnum, where the spinal cord continues caudally within the cervical spine. Superior structures sit posterior to the facial profile, while the cord tracks centrally behind the vertebral bodies and anterior to the spinous processes as it descends. For teaching neuroanatomy, this midline perspective clarifies continuity between brain, brainstem, and spinal cord in a way transverse slices cannot, especially when orienting learners to rostral to caudal relationships and the change from intracranial to intraspinal compartments. Clinically, it supports explanations of cervical myelopathy and traumatic cord injury, where canal stenosis or fracture can compress the cord within the vertebral canal while sparing the brain parenchyma. It also provides a clean setup for discussing why lesions above versus below the foramen magnum produce different patterns of cranial nerve findings, respiratory compromise, and long-tract signs. A good map. Common use cases include gross anatomy and neuroscience courses introducing the central and peripheral nervous system, board-style review figures that need an anatomic overview of the neuraxis, and patient-facing education for cervical radiculopathy versus myelopathy in spine clinics and neurosurgical consultations.
