The '''hand''' is an extremity possessed by most bipedal mammals. The hand typically contains extensions called fingers and a set of muscle groups that allow for more complicated and precise movements in comparison to the other extremities. The primary purpose of the hand is to allow an organism to physically manipulate objects in its environment. Humans and other primates use the hand as a means for building and controlling tools.

The dexterity of the human hand and the inventions it let mankind produce are just some of the reasons the human hand is one of God's greatest gifts to us.
