Nervous System, Gross Anatomy, Brown

Description

Semi-transparent cranial soft tissues on the left side reveal the cerebral hemispheres with prominent gyri and sulci of the cerebral cortex, while the brainstem continues inferiorly through the foramen magnum as the cervical spinal cord. Paired cranial nerves emerge from the ventral surface of the brain and brainstem, tracking anteriorly into the face and orbit and then inferiorly within the neck toward the upper thorax. More caudally, peripheral nerves radiate laterally from the cervical region into the shoulder girdle and descend along the torso as a branching network, emphasizing the continuity between the central nervous system and the peripheral nervous system. This head-and-upper-body perspective matters when you need to teach how focal intracranial lesions produce remote deficits along named neural pathways, for example facial weakness from a lower motor neuron facial nerve palsy versus a supranuclear stroke pattern, or diplopia from involvement of cranial nerves III, IV, or VI. The visual continuity from brainstem to cervical spinal cord also supports clinical discussions of trauma and degenerative disease at the craniovertebral junction, where compression can affect long tracts and lower cranial nerves in the same patient. It reads clearly at a glance. Use it in neuroanatomy and head and neck anatomy courses to anchor lectures on cranial nerve origins, brainstem organization, and the central versus peripheral nervous system divide, or in patient-facing neurology materials explaining why symptoms can involve the face, neck, and upper limb together. It also fits publishing layouts for chapters on cranial neuropathies, brainstem syndromes, and cervical myelopathy where a realistic portrait paired with anatomical overlay improves orientation.
