The term LEG PARTS refers to the various components of the human leg. These include the thighs, which are the uppermost part of the leg and are composed of two large muscles; the KNEES, which are the joints connecting the thigh and the lower leg; the shins, which are the front part of the lower leg; the crura, which are the two bones that make up the lower leg; and the inseams, which are the inner seams of the leg. All of these parts work together to allow humans to stand, walk, and run.
