LIGAMENTOS GLENOHUMERALES PDF

Location[ edit ] The ligaments may be best seen by opening the capsule at the back of the joint and removing the head of the humerus : [2] One on the medial side of the joint passes from the medial edge of the glenoid cavity to the lower part of the lesser tubercle of the humerus. A second at the lower part of the joint extends from the under edge of the glenoid cavity to the under part of the anatomical neck of the humerus. A third at the upper part of the joint is fixed above to the apex of the glenoid cavity close to the root of the coracoid process , and passing downward along the medial edge of the tendon of the Biceps brachii , is attached below to a small depression above the lesser tubercle of the humerus. In addition to these, the capsule is strengthened in front by two bands derived from the tendons of the Pectoralis major and Teres major respectively.

Esto ha permitido que el hombre pueda realizar infinidad de actividades gracias al uso de los miembros superiores. La mano, extremidad del miembro superior, es direccionada mediante el movimiento de las articulaciones del hombro. Las articulaciones artrodias constan de membrana sinovial, ligamentos y capsula articular, que permiten su movilidad.

Se desconocen otras funciones. Supraespinoso Se inserta desde la fosa supraespinosa articular hasta la faceta superior del troquiter humeral. Infraespinoso Se origina en la fosa infraespinosa escapular para insertarse en la faceta media del troquiter humeral. Aduce y rota internamente el brazo. Cuando ocurre en el plano frontal lo realiza sobre el eje lateral; en el plano sagital el eje correspondiente es el antero-posterior.
