In medical terminology, the leg is referred to as the lower extremity (in technical terms, Latin: membrum inferius ) . It is used for locomotion . In four-legged mammals , the corresponding limbs are known as hind legs, rear extremities or pelvic limbs ( pelvinum membrane ). With these too, they make the main contribution to locomotion. While the front limb mainly takes on the support function, the forward thrust is generated by the rear limb.
One leg consists of
- Pelvic girdle ( Cingulum pelvicum; Cingulum membri inferioris )
- Hip ( coxa )
- Hip joint ( Articulatio coxae )
Thigh ( femur )
- Knee ( articulatio genus )
- Lower leg ( crus )
- Foot ( pes ), which is composed of
In the average adult , one leg makes up 18.7% of the body weight. The absolute leg length is determined between the head of the thigh and the sole of the foot. Since the head of the femur cannot be felt, the anatomical leg length is often measured, which extends from the greater trochanter ( greater trochanter ) of the femur to the lower edge of the outer ankle . The leg length is about half the height of the adult human. In the newborn, however, the lower extremities are still poorly developed and the leg length is only a quarter of the body height.
