Beyond the metacarpals, each finger has three phalanges, while the thumb has two. The “neck” of each metacarpal bone is the thinnest part just behind the knuckle, whereas the “base” of each bone is the end situated closest to the wrist. Each of these is labeled numerically, one through five, with the first metacarpal controlling the thumb. Beyond these, the palm of the hand is made up of five total metacarpal bones. Along with the ends of the forearm’s radius and ulna, the skeletal structure of the wrist is composed of eight small carpal bones. With 27 bones and 28 muscles, the human hand is certainly nimble, but it is also highly susceptible to injury, especially acute injuries as a result of direct trauma.
