Here’s a cool visual of the subscapularis, the largest of the rotator cuff muscles. In this video, you’ll see its ability to internally rotate the humerus. More importantly, though, you have to appreciate what isn’t seen here: the pectoralis major and latissimus dorsi muscles. You see, these powerful internal rotators (and others) attach further down on the humerus, which means that they don’t have any direct control over the head of the humerus as they create that internal rotation, whether it’s in a throwing motion, dumbbell bench press, or some other IR movement. The subscapularis absolutely has to be the largest of the rotator cuff muscles because it has to “keep up with” the largest muscles of the upper body to maintain keep the humeral head (ball) centered on the glenoid fossa (socket) during internal rotation. If it doesn’t do its job, the humeral head glides can glide forward and irritate the structures at the anterior aspect of the joint: long head of the biceps tendon, glenohumeral ligaments, nerve/vascular structures, etc. 👇 This is a perfect illustration of arthrokinematics (subtle motions at joint surfaces: rolling, rocking, gliding) vs. osteokinematics (larger movements between bones: flexion/extension, abduction/adduction, ER/IR). Every gross movement of the body relies heavily on a finely tuned interaction between these two kinds of movement – and you’d be hard pressed to find a better example than subscapularis. #Repost @dr.alvaromuratore @get_repost_easily #repost_easily ****** El músculo subescapular esta ubicado en la cara anterior del hombro, su función principal es la rotación interna. En este preparado anatómico se puede ver al subescapular realizando rotación interna , además se observa la apófisis coracoides con el ligamento coracoacromial y el tendon de la porción corta del biceps.
