    • Teres Minor: Adjacente a infraspinatus, rotator externus; insere in tuberositas major humeri.
    • Subscapularis: Anteriormente in fossa subscapularis; rotator internus del hombro.

    Musculi Brachii

    • Biceps Brachii: Prima supinator del antebrachium; originat de tuberculum supraglenoidale et processus coracoideus; inserit in tuberositas radialis.
    • Coracobrachialis: Originates from processus coracoideus, debet in medial aspectum de humeri.
    • Brachialis: Profundus ad biceps, primus flexor del codo.

    Musculus Triceps Brachii

    • Compositus de tres caput: longum, laterale, et mediale; inserit in olecranon; principalis extensore del codo.

    Compartimenti Fasciales del Antebrachium

    • Compartimento Anterior: Musculi flexores, incluente pronator teres, flexor carpi radialis et ulnaris.
    • Compartimento Posterior: Musculi extensores; musculus radialis supprime.

    Retinacula de Flexione et Extension
