Introduction
In Army medical circles the view is held that of the wounded men who have returned from the French battlefields during the Great War, some 65 percent are suffering from disabilities of an orthopeclic nature; in other words, whether the injury be one of muscle, bone, joint, nerve, or central nervous system, it is of such a character that the question of muscular function becomes of prime importance for purposes of treatment. When we consider that muscular tissue alone constitutes the largest part of most animals, it is surely time that more attention was paid to the teaching of myology than has been allowed heretofore. Function of muscle the all-important factor cannot be satisfactorily taught in the dissecting room. It can only be taught on the living, and is largely a question of comparison a comparison between the normal and the paralytic. Only on this plan can the question of origin and insertion of a muscle have more than an academic, or rather examination interest for the student.
Just as important as a knowledge of the action of a muscle is a kndwledge of the action of its opponent, and the opponent should be specifically mentioned. The statement that fifteen external rotators of the hip, including such powerful engines as the psoas and great gluteus, are balanced by one muscle and part of another, can no longer be tolerated. The fact that the student when learning the action of a muscle learns that of the opponent will have an important influence on his treatment, for example, of muscular weakness, or paralysis, or of joint injuries. Thus in a case of weakness of the deltoid he will associate with ...
