Nervous System, Gross Anatomy

Description

Rendered in lateral profile, the adult female figure is shown semi-transparent to reveal the central nervous system and peripheral nervous system in continuity. The cerebrum sits superior and anterior to the brainstem, with the cerebellum posterior to the pons and medulla, and the spinal cord descending within the vertebral canal to give rise to segmental spinal nerves. Cranial nerves emerge from the brain and brainstem to course anteriorly into the face and neck, while cervical, thoracic, lumbar, and sacral spinal nerves radiate laterally and inferiorly as mixed nerves, continuing into the brachial and lumbosacral plexuses and onward to distal cutaneous and muscular branches. A true side view makes root level and body-region distribution easier to teach than an isolated diagram of the brain or cord. It helps learners connect dermatomes and myotomes to their spinal segments, a practical step when localizing neurologic deficits such as radicular pain from cervical or lumbar disc herniation. The relationship of the cranial nerves to the facial and cervical regions also supports bedside localization, for example distinguishing peripheral facial nerve palsy (CN VII) from supranuclear weakness. Use this plate in gross anatomy and neuroanatomy courses when introducing the layout of central versus peripheral pathways, or in clinical teaching materials for neurology, pain medicine, and spine surgery that need a body-context map of cranial nerves and spinal nerve outflow. It also fits well in patient-facing education for neuropathy, sciatica, and brachial plexus injury where a clear whole-body overview reduces abstraction.
