The Human Hand

 

Few structures of human anatomy are as unique as the hand can be divided into several different categories that includes joints, ligaments, tendons, muscles, nerves, and blood vessels. Today we will talk about bones, tendons, and muscles. 

Let's start with bones. The bones in your forearm are called the Ulna and Radius, those bones then connect to your wrist or Carpal bones, which connect to your Metacarpal bone of your palm and then your Phalanges or fingers. An interesting thing about the hand is that there are no muscles in your hand at all only tendons. The tendons in your hand connect to the muscles in your forearm, that is why when you wiggle your fingers your forearm moves because when the muscle flexes in your arm it pulls or releases the tendons and makes your finger move.
