The brachialis muscle originates from the anterior surface of the distal half of the humerus, just distal to the insertion of the deltoid muscle. It is also attached to the intermuscular septa of the arm on either side, with a more extensive attachment to the medial intermuscular septum. The fibers of brachialis extend distally to converge on a ...Origin [edit | edit source] The infraspinatus fossa of scapula, with some fibres arising from the infraspinatous fascia which covers the muscle and separates it from Teres Major and Teres Minor. Insertion [edit | edit source] The posterior aspect of greater tuberosity of humerus, and the capsule of shoulder joint. Nerve Supply [edit | edit source]Conclusions: LT provided better abduction and external rotation moment arms when transferred to the infraspinatus insertion. LD performed better when transferred to the supraspinatus insertion. Overall, LT transfer showed a biomechanical advantage compared with LD transfer because of stronger abduction moment arms. However, significantly …

RESULTS. The mean size of supraspinatus tendon tears in the SS normal (n = 45) group was 8.5 mm, 16.6 mm in SS volume loss (n = 53), and 29 mm in the SS fatty atrophy group (n = 44). Subscapularis tendon abnormality was identified in 22% of SS normal patients, 61% of SS volume loss, and 86% of the SS fatty atrophy group (p < 0.001). There was moderate correlation between chronicity of ...Jul 3, 2023 · The infraspinatus muscle is a crucial component of the shoulder complex, playing a vital role in the stability and movement of the shoulder joint.

Sternocleidomastoid muscle. The sternocleidomastoid muscle is a two-headed neck muscle, which true to its name bears attachments to the manubrium of sternum (sterno-), the clavicle (-cleido-), and the mastoid process of the temporal bone (-mastoid).
