Though a human hand is simple to look at, there are many factors that allow it to do what it does. There are the bones that give it shape, the muscles that give the hand strength, and the tendons and ligaments that control the bones themselves, making the hand move. Learning about the hand is an important step for biology students, but it is not always easy to remember. A good pamphlet on the subject allows them to remember the key parts of the hand and what they do.
