We investigated the function of biceps in 18 patients (19 shoulders) with lesions of the rotator cuff. Their mean age was 59 years. Another series of 18 patients (19 shoulders) with normal rotator cuffs as seen on MRI acted as a control group. Their mean age was 55 years. A brace was used to maintain contraction of biceps during elevation. Anteroposterior radiographs were obtained with the arm ...

Contribution of synergistic muscles toward specific movements over multi joint systems may change with varying position of distal or proximal joints. Purpose of this study is to reveal the relationship of muscular coordination of brachioradialis and biceps brachii during elbow flexion with respect to hand position and biomechanical advantages and disadvantages of biceps brachii. A group of 16 h...

Muscles control body posture and movement by extrafusal and intrafusal (muscle spindle) fibres. The purpose of this thesis was to provide insight into the muscular basis for human jaw function at young age. Extrafusal and intrafusal fibres in the young masseter, and for comparison young biceps, were examined for composition of fibre types and myosin heavy chain (MyHC) isoforms by means of morph...

ganglion cysts commonly occur around the shoulder, mostly in the spinoglenoid and suprascapular notches. we report a very rare case of intra articular ganglion cyst of the long head of the biceps tendon that originated from the bicipital groove as a rare cause of shoulder pain.

The bicipital aponeurosis (BA) is a fascial expansion which arises from the tendon of biceps brachii and dissipates some of the force away from its enthesis. It helps in dual action of biceps brachii as supinator and flexor of forearm. The aim of the present work was to study the morphology of BA. Thirty cadavericupper limbs (16 right and 14 left side limbs) were dissected and dimensions ofthe ...

The innervation of the biceps muscle was examined in regenerated and vitamin A-induced serially duplicated axoloti forelimbs using retrograde transport of horseradish peroxidase. The regenerated biceps muscle becomes innervated by motor neurones in the same position in the spinal cord as the normal biceps motor pool. In previous experiments in which the innervation of a second copy of a proxima...

The hamstring muscle group consists of three muscles in the posterior thigh; the semitendinosus (ST) and the semimembranosus (SM) are located at the medial side, the biceps femoris at the lateral side (BF) [1]. The biceps femoris has two heads, which are anatomically and functionally distinct; the short (BFsh) and the long (BFlh) head. The semitendinosus and long head of the biceps femoris have...
