what are calf muscles called
Images: Here you can see the calf muscles, first the superficial muscles. The two headed calf muscle (4) is removed in the 3rd picture. You can find the legend at the end of this page: Legend. The calf (sural region) is the rear upper muscular region of the lower leg. Not all muscles in the calf are calf muscles, however. The calf is defined largely as the three headed calf muscle (triceps surae muscle). You can find more details under the headings superficial lower leg muscles and deep lower leg muscles.
