3D ANATOMY - Deep dissection of the posterior body wall/ventral

This 3D printed model provides a detailed ventral view of the head, neck, thorax, abdomen, and proximal thighs, offering insight into the central nervous system, nerve plexuses, and major vascular structures.
It serves as a complementary piece to the dorsal dissection model (MP1400).
Brain and Upper Spine
The facial skeleton is removed, exposing both cerebral hemispheres, parts of the Circle of Willis, and key arteries (vertebral, basilar, AICA, labyrinthine). Several cranial nerves (II, III, V, VI) and the right internal carotid artery are preserved. Below, the anterior spinal cord, vertebral arteries, and cervical and brachial plexus roots are visible, along with CN X, CN XII, and the sympathetic trunks.
Axillae and Upper Limbs
The anterior thoracic wall, clavicles, and first ribs are removed to expose both axillae, with clear views of the brachial plexus, axillary arteries, and surrounding musculature. The proximal upper limbs are preserved to mid-arm level.
Thorax and Lumbar Region
The spinal cord extends to the conus medullaris, with ventral nerve roots and sympathetic chains visible throughout. Splanchnic nerves, intercostal nerves, and abdominal wall nerves (e.g., ilioinguinal, genitofemoral, femoral) are preserved. On the right, removal of the psoas muscle exposes the lumbar plexus.
Pelvis and Proximal Thigh
The pelvic viscera are removed, but the pelvic floor, rectum, and lumbosacral plexus remain. Obturator nerves are visible entering the obturator canals, and the femoral vessels are retained in both femoral triangles.
This model is ideal for studying ventral CNS access, neurovascular pathways, and regional anatomical relationships across the entire torso.
