All the muscles assisting in running, walk-ing, or dancing, are variously connected with it. BONES OF THE LEG. — Tibioz. Tibia is the scientific name of the shin bone, becauseit was thought to look like a pipe. United with the con-dyle of the thigh bone, assisted only by the knee pan, theknee joint is formed. At the ankle, it is admirably fitted to the astragalus, topermit flexion and extension of the foot, as in piece or splint, called maleolar process, slides down bythe side of the joint, to increase its strength. The pro-cess may be felt, being under the skin like a knob, on theinner side of the ankle. This joint is very securely arranged, to prevent luxa-tions : as it merely moves in two directions, backward andforward, — nothing short of a degree of violence that in-jures the bones, can materially affect it. Beside its lig-aments, the tendons of many muscles contribute to itssecurity, strength and perfection. 32 ANATOMICAL CLASS 4 3 3 5 2 7 6 Explanation of Fig. three plans show how the two bones of the leg are unitedabove the ankle joint— 1, 2, 3, 4, 5, 7, 7, 6 — mark the ligamentswhich bind them so firmly. Outside of the tibia, is a long, slender bone, the Jibula,lying on the side of the head of the tibia, but havingnothing to do with the knee joint; — it passes down pastthe ankle joint, giving the same security to it, that is af-forded by the maleolar process of the tibia, on the the two bones, all the muscles, and they arenumerous, arise, which go to the foot and toes. BONES OF THE INSTEP Ossa Tarsi. Five bones are found in the tarsus or instep, one ofwhich is nearly all given to the heel. An arch is formedby the other four, similar to the wrist, giving a convexity ANATOMICAL CLASS BOOK. 33 Fi2. 52.
