Most of us study human anatomy in high school or college. We learn about bones, muscles and tendons, which are the three building blocks of most joints.
Well, a good action figure has plenty of joints as well, and they’re worth knowing if you’re a collector. Fortunately, unlike human joints, which have names like acromioclavicular and carpometacarpal, our joints don’t sound like the sort of words Harry Potter and Voldemort might shout out while shooting their wands at each other. They have much simpler names, but they can do almost as much.
