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. In bipedal animals with an upright posture (e.g. humans and some other primates), the term upper limb is often used.

The 5 papillae are filiform, fungiform, foliate, vallate, and conical. [2] Papillae allow a cat to groom itself. [3] A cat's sense of smell and taste work closely together, having a vomeronasal organ that allows them to use their tongue as scent tasters, [4] while its longitudinal, transverse, and vertical intrinsic muscles aid in movement.

In terrestrial vertebrates, digitigrade (/ ˈ d ɪ dʒ ɪ t ɪ ˌ ɡ r eɪ d /) [1] locomotion is walking or running on the toes (from the Latin digitus, 'finger', and gradior, 'walk').A digitigrade animal is one that stands or walks with its toes (phalanges) on the ground, and the rest of its foot lifted.
The ZPA also plays an important role in initially specifying digit identity, while later maintaining proper AER morphology and continued FGF8 secretion – to ensure proper mitotic activity of the limb bud mesenchyme beneath. [3] In chickens, Tbx4 specifies hindlimb status, while Tbx5 specifies forelimb status. [13]

They may or may not perform the same function. An example is the forelimb structure shared by cats and whales. Analogous structures - structures similar in different organisms because, in convergent evolution, they evolved in a similar environment, rather than were inherited from a recent common ancestor. They usually serve the same or similar ...
In humans, each upper limb is divided into the shoulder, arm, elbow, forearm, wrist and hand, [2] and is primarily used for climbing, lifting and manipulating objects. In anatomy , just as arm refers to the upper arm , leg refers to the lower leg .
