3D ANATOMY - Nervous system dissection

This detailed 3D printed specimen provides a unique dorsal view of the head, neck, thorax, abdomen, and gluteal regions, highlighting the central nervous system and segmental nerves in anatomical context.
The model reveals deep structures through extensive removal of posterior elements, including the posterior cranium, vertebral arches, and parts of the thoracic and gluteal walls.
Cranial and Cervical Structures
The posterior skull is removed to display a coronal section of the cerebral hemispheres, separated by the falx cerebri and bordered by a preserved superior sagittal sinus. The cerebellum is removed, exposing the fourth ventricle, pons, medulla oblongata, and cranial nerves VII–XII. The vertebral arteries are visible ascending through the transverse foramina and curving toward the foramen magnum. The cervical and brachial plexus roots are shown resting on scalene muscles and major vessels, extending into the axilla.
Axilla and Upper Thorax
The scapulae are partially (left) or fully (right) removed, allowing visualization of the brachial plexus and axillary vessels.
On the left, parts of deltoid, infraspinatus, and teres minor remain, while the long thoracic nerve, lateral thoracic artery, and subscapular branches are preserved.
On the right, the axillary nerve and posterior circumflex humeral artery are shown passing toward the surgical neck of the humerus.
Thoracic Spine and Intercostal Nerves
A laminectomy reveals the spinal cord, dorsal roots, and ganglia.
On the right, the posterior thoracic wall is removed (ribs 2–12), exposing the lung and diaphragm.
On the left, ribs 3–5 are retained to show intercostal musculature and nerve positioning, with the full set of intercostal nerves preserved.
Lumbar Region and Abdomen
The lumbar spinal cord is opened to show the conus medullaris and cauda equina.
On the right, the quadratus lumborum is removed, exposing subcostal and lumbar nerves along the psoas.
On the left, the subcostal nerve, kidney, and jejunum are visible through an opened peritoneal cavity.
Gluteal and Pelvic Dissection
In the gluteal region, gluteus maximus is removed bilaterally:
Left side: Gluteus medius is preserved; the superior and inferior gluteal arteries and nerves, internal pudendal vessels, and the sciatic nerve are visible relative to the piriformis and lateral rotators.
Right side: Deeper dissection reveals the lumbar and sacral plexuses within the true pelvis.
This model offers a rare, continuous view of deep axial anatomy, perfect for advanced anatomical study, neuroanatomy training, and surgical reference.
