limb 'lim n
1) one of the projecting paired appendages (as an arm, wing, fin, or parapodium) of an animal body made up of diverse tissues (as epithelium, muscle, and bone) derived from two or more germ layers and concerned esp. with movement and grasping but sometimes modified into sensory or sexual organs esp a human leg or arm

(lim) 1. one of the paired appendages of the body used in locomotion or grasping. The terms arm and leg are commonly used for the human upper and lower limbs, but in technical anatomical terminology those terms refer to only part of their respective limbs. In embryology, the skeleton of each limb is divided into four main parts: the zonoskeleton, comprising the scapula and clavicle (as a unit) and the hip bone; the stylopodium, comprising the humerus and femur; the zygopodium, comprising the radius and ulna and the tibia and fibula; and the autopodium, comprising the hand and the foot. Called also member and extremity. 2. a structure or part resembling an arm or leg.
