from the anteromedial surface of the shaft of the humerus, near the insertion of coracobrachialis
and just above the origin of brachialis.
Four-headed biceps brachii, three-headed coracobrachialis
muscles associated with arterial and nervous anomalies in the upper limb.
The posterior deltoid (innervated by the axillary nerve) will refer locally and into the posterior upper arm while the coracobrachialis
(innervated by the musculocutaneous nerve) will refer in the posterolateral arm and forearm.
Is the musculocutaneous nerve really in the coracobrachialis
muscle when performing an axillary block?
Muscles involved in amplexus, such as pectoralis, coracoradialis, coracobrachialis
, flexor carpi radialis, extensor carpi radialis, sternoradialis and abductor indicus longus were found to be larger in males than in females (Oka et al.
functions as a static and dynamic stabilizer to the inferior part of the capsule during shoulder abduction and simultaneous elbow flexion.
En un 70 % de los casos, la cabeza supernumeraria del musculo biceps brachii toma insercion proximal a nivel de la cara anterior del humero por debajo de la insercion distal del musculo coracobrachialis
y encima de la insercion proximal del musculo braquialis y en un 30 % desde la parte anterior y media del borde medial del humero (7).
The lateral cord innervates the biceps and coracobrachialis
muscles via the musculocutaneous nerve.
The musculocutaneous nerve arises from the lateral cord, perforates the coracobrachialis
muscle and leaves the neurovascular sheath usually at the level of the lateral edge of the pectoralis major.
During surgical exploration under axillary block, we found a lipoma extending from the coracobrachialis
and the short head of biceps up to the brachialis muscle.
biceps brachii, coracobrachialis
, and anterior deltoid), the findings in the present study indicate that the 2-min rest interval between sets was more effective than the 1-min rest interval in relation to the maximum number of repetitions performed for the multi-joint bench press exercise.
muscle arises from the apex of the coracoid process, together with the tendon of the short head of the biceps, and also by muscular fibres from the proximal 10 cm of this tendon.
