Ritz argued that the engrossed copy of the Declaration was signed by Congress on July 4, as Jefferson, Adams, and Franklin had stated, and that it was implausible that all three men had been mistaken. Ritz believed that McKean's testimony was questionable, and that historians had misinterpreted the July 19 resolution.
The seven general types of skeletal muscle. The origin of a muscle is the bone, typically proximal, which has greater mass and is more stable during a contraction than a muscle's insertion. For example, with the latissimus dorsi muscle, the origin site is the torso, and the insertion is the arm.
Ends: A typical skeletal muscle consists of two ends. These are; 1  Origin is one end of the muscle which remains fixed during its contraction. 2  Insertion is the other end which moves during its contraction. 3  In the limb muscles, the origin is usually proximal to insertion.arts: A typical skeletal muscle consists of two parts. These are; 1  Fleshy part is contractile, and is called the âbellyâ. 2  Fibrous part is non-contractile and inelastic. 3  When cord-like or rope-like, it is called tendon; when flattened, it is called aponeurosis.
