Nervous System, Black

Description

Posterior anatomy frames the central nervous system in continuity with the peripheral nervous system, with the brain visible within the cranial vault and the spinal cord descending in the vertebral canal to the conus medullaris and cauda equina. Segmental spinal nerves exit bilaterally and course laterally into the cervical, brachial, intercostal, lumbar, and sacral distributions, then arborize into cutaneous and muscular branches across the shoulders, back, upper limbs, and lower limbs. Proximally, the major plexuses sit deep and medial near the vertebral column, while more distal nerves fan superficially toward the dorsum of the hand and foot. A posterior view clarifies how dermatomes map to spinal segments and why radicular pain often wraps around the trunk or runs longitudinally down an extremity. It also supports teaching around common compressive neuropathies and entrapment sites that clinicians approach from the back, such as dorsal scapular nerve irritation near the medial scapular border or posterior interosseous nerve involvement with proximal forearm pain patterns, while keeping the spinal cord and nerve roots as the primary reference. Clean segmental organization. It makes myotomes easier to explain. Use this artwork for neuroanatomy and gross anatomy modules that introduce spinal nerves, plexus formation, and peripheral nerve field testing, or for textbook figures discussing radiculopathy, brachial plexopathy, and peripheral neuropathy patterns on physical exam. It also fits patient-facing neurology and rehabilitation materials where a transparent body overlay helps contextualize symptoms without crowding the musculoskeletal system.
