A<unk>  is a prehensile, multi-fingered appendage located at the end of the forearm or forelimb of primates such as humans, chimpanzees, monkeys, and lemurs. A few other vertebrates such as the koala (which has two opposable thumbs on each "hand" and fingerprints extremely similar to human fingerprints) are often described as having "hands" instead of paws on their front limbs. The raccoon is usually described as having "hands" though opposable thumbs are lacking. Some evolutionary anatomists use the term<unk>  to refer to the appendage of digits on the forelimb more generally — for example, in the context of whether the three digits of the bird<unk>  involved the same homologous loss of two digits as in the dinosaur<unk> . The human<unk>  usually has five digits: four fingers plus one thumb; these are often referred to collectively as five fingers, however, whereby the thumb is included as one of the fingers. It has 27 bones, not including the sesamoid bone, the number of which varies among people, 14 of which are the phalanges (proximal, intermediate and distal) of the fingers and thumb. The metacarpal bones connect the fingers and the carpal bones of the wrist. Each human<unk>  has five metacarpals and eight carpal bones. Fingers contain some of the densest areas of nerve endings in the body, and are the richest source of tactile feedback. They also have the greatest positioning capability of the body; thus, the sense of touch is intimately associated with<unk> s. Like other paired organs (eyes, feet, legs) each<unk>  is dominantly controlled by the opposing brain hemisphere, so that<unk> edness—the preferred<unk>  choice for single-handed activities such as writing with a pencil, reflects individual brain functioning. Among humans, the<unk> s play an important function in body language and sign language. Likewise, the ten digits of two<unk> s and the twelve phalanges of four fingers (touchable by the thumb) have given rise to number systems and calculation techniques.
