Hand

The proximal most part of the upper limbs(naturally always in a pair) of biologically classified primates usually used to support walking in primitive primates. Hands may be used to perform precision demanding jobs such as using tools. Humans and some intelligent primates use their hands to handle tools or grab objects. Hands consist of a central and swollen palm(mostly non pigmented) and usually 5 digits attached to the palm through bones. One of the digits is a thumb which may or may not be free determining the flexibility of the hand useful in carrying objects. A free thumb in Homo sapiens has allowed the species to carry or hold objects with much ease and perform various activities using intricate finger movement.
