Leg anatomical model MP1809

for teaching

This 3D printed specimen presents a right lower limb, sectioned just above the knee and including a partially dissected foot, showing detailed structures on the dorsum. Proximal Section & Popliteal Fossa The proximal cross-section shows the patella articulating with the distal femur. Posteriorly, the superior popliteal fossa is preserved, revealing the popliteal artery, vein, and terminal sciatic nerve. Distal Leg & Neurovascular Structures Distal to the knee, most posterior muscles are removed to highlight neurovascular structures, including the common peroneal and tibial nerves as well as the posterior and anterior tibial arteries. The popliteus muscle and the interosseous membrane between tibia and fibula are visible. Medially, the pes anserinus inserts onto the proximal tibia; laterally, the biceps femoris inserts into the fibular head near the common peroneal nerve. Muscle Compartments & Tendons Most of the posterior and lateral compartment muscles are removed, leaving the anterior compartment intact and visible under the crural fascia. The anterior tibial artery and vein pass distally deep to the exposed interosseous membrane. Distal tendons of the anterior muscles pass beneath the extensor and peroneal retinaculae to their insertions. Foot & Dorsum On the dorsum, the dorsalis pedis artery and the terminal deep peroneal nerve are visible between the extensor hallucis longus and extensor hallucis brevis tendons. The extensor digitorum brevis is clearly seen beneath the extensor digitorum longus and peroneus tertius tendons.
