2023年11月3日 · The subscapularis muscle participates in formation of the three intermuscular axillary spaces; Quadrangular space; subscapularis forms the anterior boundary of this space, while the shoulder joint capsule and teres minor bound it superiorly, teres major inferiorly and the surgical neck of the humerus laterally.

2023年11月3日 · The anterior aspect of teres major is in relation with the subscapularis muscle. The inferior margin of teres major is parallel to the superior border of the latissimus dorsi muscle. The adjoining fibers of these two muscles may be fused in some individuals.

Muscle Test Group: Teres major, subscapularis. Key Points: Teres major and subscapularis are tested as a group; they provide medial rotation of the shoulder joint. These muscles are a part of the strong medial shoulder rotators.

2023年4月17日 · The rotator cuff muscles (supraspinatus, infraspinatus, teres minor, and subscapularis) assist the teres major in stabilizing the humeral head. Together, these muscles are crucial to preventing subluxation of the humeral head.

2023年5月5日 · The teres major is a rectangular, thick, flat shoulder muscle extending from the lower scapular region below the armpit to the upper (proximal) part of the humerus’s shaft. It is one of the 7 scapulohumeral muscles that attach the humerus to …

Teres major (TM) is a small muscle that runs along the lateral border of the scapula. It is one of the seven scapulohumeral muscles that act around the glenohumeral joint to facilitate shoulder movement [1]. [2] . It's sometimes called "lat's little helper" because of its synergistic action with the latissimus dorsi. [3] Image 1: Red shows TM.

2024年10月21日 · The subscapularis, along with the teres major and latissimus, forms the posterior axillary wall. It also joins the teres major and minor, the glenohumeral joint capsule, and the humerus in forming the three axillary spaces: the upper and lower triangular spaces and the quadrangular space.

2024年9月28日 · Teres Major. The teres major forms the inferior border of the quadrangular space – the ‘gap’ that the axillary nerve and posterior circumflex humeral artery pass through to reach the posterior scapular region. Attachments: Originates from the posterior surface of the inferior angle of the scapula. It attaches to the medial lip of the ...

2023年8月28日 · The subscapularis is one of the four muscles which compose the rotator cuff apparatus. The other three are the supraspinatus, infraspinatus, and teres minor muscles. The subscapularis muscle’s primary function is internal rotation but …

Muscle anatomy of the subscapularis includes origin, insertion, action, innervation and vascular supply. Actions include agonists and antagonists for each movement.
