Nervous system model MP1400

for teaching

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
