leg,

one of the paired limbs of an animal used for support of the body and for locomotion. Properly, the human leg is that portion of the extremity between the foot and the thigh. This section of the human leg contains two long bones, the tibia and the fibula. The upper end of the tibia joins with the lower end of the thighbone (femur) and forms a hinged joint. The kneecap (patella), a flat triangular-shaped bone, surrounds and protects this joint. The lower end of both tibia and fibula join with the talus, a bone in the foot, to form the ankle joint. The upper end of the femur, which is the longest bone in the body, forms a ball and socket joint where it meets the hipbone. In quadrupeds, both the hind and fore limbs are referred to as legs.

Leg

 

an organ of support and locomotion in animals and man (seeMOVEMENT, LOCOMOTION). In mollusks, the analagous organ of locomotion is called the foot, which occurs as an unpaired muscular outgrowth of the ventral wall of the body. The foot is often supplied with a flat, creeping basal plate and contains glands that secrete mucus or byssal threads (seeBYSSUS). The development and structure of the foot depend on the mollusk’s mode of life. For example, in swimming pteropods the foot is in the form of two fins, which are shaped like oars. In sessile and parasitic mollusks the foot is reduced to various degrees, depending on the species. In cephalopods it has been converted to a funnel and a crown of tentacles.
