In the sixth volume, you’ll assemble an accurate cross-cut section of the right leg that gives you a detailed interior view from posterior’s gluteus medius muscle to toe’s extensor hallucis longus tendon. Focusing on musculature, this puzzle shows how each muscle and tendon relates to the next. Together, this soft tissue enables locomotion. Hip and thigh muscles provide lateral movement, rotation, and flexion, allowing us to crawl and overcome hurdles; calf and ankle muscles provide extension and flexion, allowing us to spring off the ground and land upright on uneven terrain. A complex network of nerves, arteries, and veins is interwoven, constantly repairing our muscles and collecting information about our environment.
