A forelimb or front limb is one of the paired articulated appendages attached on the cranial end of a terrestrial tetrapod vertebrate's torso.With reference to quadrupeds, the term foreleg or front leg is often used instead.

One of the many differences between quadrupedal mammals and birds is that during standing, the forelimbs in mammals are involved in locomotion and support of the body, whereas the forelimbs of birds are involved in locomotion but not in body support. The Clavicle is all but absent in most domestic species, with the notable exception of the avian skeleton. Each fused vertebra of in vivo clinical intervertebral disk disease in this has a prominent spine on the dorsal surface; these spines species.14 occasionally have bifid summits.1,9 On either side of the spinous processes lie four paired foramina.

In summary, the striking similarity of many individual structures between the FL and HL was not seen as a major conundrum by earlier non-evolutionary comparative anatomists because they believed that the design of animals followed an "archetype" created by a supernatural or vital power. .

The number of metacarpals varies widely among species, as the demand for their function changes: plantigrade, or flat-footed, animals requiring the full complement of five metacarpal bones; the number is reduced in the upright stature of digitigrade animals such as the dog and cat, and shows the extreme in unguligrades like the horse, which depends entirely on the third metacarpal bone for its stature.
