Fig. 1. A front View of the Muscles of the Body.

A. a broad muscle helping to depress the angle of the mouth and also when the mouth is shut draws up the skin with which it is connected below the lower jaw. B. Deltoid muscle, used to raise the arm and assist it in all its motions except depressing it. C. Muscle. used to bend the forearm. I. Moves the arm forward and upward toward the sternum. R. Assists in expiration and occasionally in discharging the contents of the stomach and belly. 0. Crosses the legs in the manner tailors are used to sit. P. Draws the legs and thigh outward. Q. Helps to bend the leg and assists in bringing it and the thigh inward. T. Pulls the thigh inward. V.W.X. Help to extend the leg. Y. Extends the foot.

Fig. 2. Represents the extensors of the hand and forearm. The tendinous extremities are seen passing under the ligament at the root of the thumb and firmly bound by ligaments to the fingers. They serve to extend the hand and forearm. The flexors placed on the opposite side of the hand not seen in the cut serve to flex the hand and arm, and other muscles in connection with these and the extensors serve to rotate the hand and arm.

Fig. 4. Represents the muscles of the anterior portion of the leg and foot together with the arteries and nerves. The muscles of the leg may be seen passing under the broad ligament at the ankle, and attached by their tendinous extremity to the foot. These serve to flex the foot, and also to extend and rotate the leg. 1. Tibial artery. 2. The great sciatic nerve which may be seen dividing into various branches along the leg and foot.
