They compose the substance known by the name of redflesh, and a good idea may be formed of them by examiningthe red flesh of quadrupeds. Their characteristic propertyis contractility, and there is neither action nor repose inthe position of any of our limbs without muscular contraction.For every moveable point in the animal frame is constantlysituated between two muscular powers opposed to eachother ; between those of flexion and extension, of elevationand depression, of adduction and abduction, etc. ; this oppo-sition is a condition essential to motion, for in whateverdirection the limb is moved the moveable point must neces-sarily be in the opposed direction, the act of flexion requiresit should be first extended, and vice versa.
