Limb (anatomy)

Moved by muscles paired appendages, which consist of different members

A limb (from Old English lim, meaning "body part") is a jointed, muscled appendage of tetrapod vertebrate animals used for weight-bearing, terrestrial locomotion and physical interaction with other objects. The distalmost portion of a limb is known as its extremity. The limbs' bony endoskeleton, known as the appendicular skeleton, is homologous among all tetrapods, who use their limbs for walking, running and jumping, swimming, climbing, flying, grasping, touching and striking.
