Each muscle has at least two attachments, known as origin and insertion. The origin is the point which usu- ally remains fixed while the muscle contracts. The insertion or termination is the point which is fixed to the bone that is displaced by the muscular contraction. This is not a hard-and-fast rule, for the action may lie reversed and the insertion Ijecome the origin, as is the case when the heatl and neck are in

Muscles are arranged in groups that oppose each other when they act on the. Fig. 9.—Cross-section of left leg, cut a little above middle: u, Tibia; h, fibula; d, I, m, tendons of muscles; c, e,f, g, h, i, k, ti, fleshy portions of muscles; o, skin; p, s, iv, arteries; r, x, veins; q, <j', r, I, ii, ij, nerves. (EUenberger in Leisering's Atlas.) joints, one group acting as flexors and the antagonistic group as extensors. To facilitate the play of a muscle or tendon over bony promi- nences are liursse and tendon sheaths. Bursas are small sacs filled with a fluid which resembles synovia. They form pads to prevent friction. The tendon sheaths are elongated, closed sacs containing serous fluid. They are folded completely around the tendons, as the diagram (Fig. 10) shows. Each skeletal muscle has a name. Names of muscles have.
