A hand 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 phalanges are numbered I through V, like the metacarpals. Each phalanx then is named according to which hand it comes from, which number it is, and whether it is proximal, middle, or distal. So the second phalanx on the pointing finger in Figure 7-12 is the left medial phalanx II.

Whilst the great toe (hallux) is comprised of only two phalanges (proximal and distal). We encourage you to take a look at our study materials to find out more about the bones of the foot and foot ligaments.
A finger is a limb of the human body and a type of digit, an organ of manipulation and sensation found in the hands of humans and other primates. Usually humans have five digits, the bones of which are termed phalanges, on each hand, although some people have more or fewer than five due to congenital disorders such as polydactyly or oligodactyly, or accidental or intentional amputations.
