The way that bones, muscles and tendons all connect is pretty impressive in its elegance.
Did you know? Hands contain 29 bones, 17 muscles, 123 ligaments, and various arteries and nerves. There are then another 18 muscles in the forearm that help operate the hand and fingers and thumb.
What results is a part of our anatomy, which is very flexible, durable and highly functional. Our opposable thumbs are a clever piece of design, and as advanced primates, we put them to good use.
