Prevalencia de Cabeza Accesoria (Humeral) del Músculo Bíceps Braquial: Revisión de la Literatura

Abstract: CÁRDENAS, J. G.; BERNAL, M.; IZCURDIA, C. E. & OTTONE, N. E. Prevalencia de cabeza accesoria (humeral) del músculo bíceps braquial. Revisión de la literatura. Int. J. Morphol., 35(3):1095Morphol., 35(3): -1101Morphol., 35(3): , 2017. RESUMEN:Las variaciones anatómicas del miembro superior son frecuentes. El músculo bíceps braquial está considerado como uno de los músculos que más variaciones presenta, sobre todo en cuanto al número y morfología de sus cabezas. Su importancia excede lo meramente descriptivo ten… Show more

“…In electromyographic studies in Hylobates , the origin of the short head on the humerus decreases its capacity for shoulder flexion, but increases the strength of elbow flexion due to the increased origin area . This is similar to the condition of the humeral head in S leucopus , where the humeral head of biceps brachii increases the strength of supination . Domestic mammals do not have a short head of the biceps brachii muscle, and it acts as a flexor of the elbow and in addition to an extensor of the shoulder .…”

“…In addition, several variations have been reported in humans, such as the agenesis of the long head tendon, two long heads, complete separation of both heads, and supernumerary heads . The supernumerary head may present as a humeral head that originates from the antero‐medial surface of the humerus between the origin of the brachialis muscle and the insertion of the coracobrachialis muscle, which may also be found in S leucopus as a variant. In humans, however, the presence of this supernumerary head has occurred in concert with the duplication of the musculocutaneous nerve ; this disposition was not found in S leucopus .…”
