hand

Also known as manus

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 raccoon is usually described as having "hands" though opposable thumbs are lacking.

AI overview

A hand is a flexible, multi-fingered appendage at the end of the forearm found in primates like humans and chimpanzees, and in some other animals like koalas and raccoons. Hands matter because their design—particularly features like opposable thumbs in many species—enables these animals to grasp, manipulate objects, and perform complex tasks.

Some evolutionary anatomists use the term hand 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 hand involved the same homologous loss of two digits as in the dinosaur hand.
