It can be affected by the magic angle effect especially in the curve as it encircles the humeral head and enters the bicipital groove. Moreover, MRI can depict most biceps tendon pathologies except for ...Spinalis is the most medial of the three erector spinae muscles. Like the other two, it is made up of three parts. Spinalis and longissimus both have capitis, cervicis and thoracis parts, while iliocostalis has cervicis, thoracis and lumborum parts.

The nerve is fixed at both its origin at the Erb point on the brachial plexus and at its terminal insertion on the infraspinatus. The nerve is relatively fixed at the suprascapular notch, and anatomical studies have shown that motion does not occur ...

Infraspinatus: The infraspinatus is a triangular muscle, which holds the chief part of the infraspinatous fossa. The infraspinatus is one of the four rotator cuff muscles. Origin: Infraspinatus originated from Infraspinous fossa of the scapula. Insertion: It inserts to the Middle facet on greater tuberosity of humerusThe shoulder joint, also known as the glenohumeral joint, is a ball and socket joint with the most extensive range of motion in the human body. The shoulder muscles have a wide range of functions, including abduction, adduction, flexion, extension, internal and external rotation.[1] The central bony structure of the shoulder is the scapula, where …The teres major is a thick but flattened, rectangular muscle that extends from the inferior posterior scapula to the medial lip of the intertubercular groove of the humerus.[1][2] It functions synergistically with the latissimus dorsi to extend, adduct, and internally rotate the humerus.[3] Although the latissimus dorsi and teres major muscles often function in conjunction with one another ...The subscapularis muscle is one of the four muscles that make up the rotator cuff, the others being: supraspinatus, infraspinatus and teres minor..

The primary function of the teres minor is to modulate the action of the ...The lattissimus dorsi muscle (sometimes translated as the "broadest muscle of the back") is a flat triangular muscle caudal to scapula.Origin: Begins as a wide, tendinous leaf from the superficial leaf of the lumbosacral fascia and thus from the spinous processes of the lumbar vertebrae and the last seven or eight thoracic vertebrae, and it arises muscularly from the last two or three ribs ...…
