Nervous System, Gross Anatomy

Description

Spanning from the cranial vault to the distal extremities, the female nervous system is rendered with the central nervous system in continuity with the peripheral nerves. Superiorly, the brain occupies the cranial cavity and transitions caudally into the spinal cord within the vertebral canal, from which segmental spinal nerves emerge bilaterally. In the trunk and limbs, major peripheral pathways course laterally and distally from the cervical, thoracic, lumbar, and sacral regions, forming paired nerve distributions into the upper limbs and lower limbs with a largely symmetrical left to right pattern. Clinically, a whole-body mapping like this helps correlate focal neurologic deficits with lesion level, distinguishing a central pattern (brain or spinal cord) from a peripheral pattern (plexus, root, or named nerve). The continuity of the spinal cord with exiting spinal nerves supports teaching of radiculopathy and dermatomal referral, such as cervical root compression producing arm pain or lumbar root involvement producing sciatica-like symptoms along the posterior thigh and leg. It also orients viewers to where nerve injury commonly occurs along long peripheral courses, including traction and entrapment sites in the upper limb and lower limb. Use this illustration for gross anatomy and neuroanatomy teaching when you need a single plate that ties brain and spinal cord to the peripheral nervous system in a female body habitus, with clear bilateral organization for side-to-side comparison. It also suits patient education handouts and textbook chapters discussing central versus peripheral localization, polyneuropathy distributions, and the anatomic basis of referred pain.
