The sixth volume of Dr. Livingston's Anatomy Jigsaw Puzzle is The Human Right Leg, which focuses on the musculature of the legs, and 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. Interwoven throughout is a complex network of arteries, veins, and nerves, constantly collecting information about our environment and repairing our muscles. Familiarize yourself with just a few of the things that our bodies do without us even thinking about it.
