Dec 5, 2022 · Supraspinatus is the most superior of the four rotator cuff muscles. It is a small triangular-shaped muscle, located on the posterior aspect of the scapula. It originates from the medial aspect of the supraspinous fossa, a concave depression located above the spine of the scapula.
The supraspinatus (pl.: supraspinati) is a relatively small muscle of the upper back that runs from the supraspinous fossa superior portion of the scapula (shoulder blade) to the greater tubercle of the humerus.
Supraspinatus is the smallest of the 4 muscles which comprise the Rotator Cuff of the shoulder joint specifically in the supraspinatus fossa. It's considered as the most superiorly located of the rotator cuff muscles.
Jan 26, 2024 · The supraspinatus is an intrinsic muscle of the shoulder region. It is part of the rotator cuff muscle group. Attachments: Originates from the supraspinous fossa of the scapula and attaches to the greater tubercle of the humerus. Actions: Abduction of the upper limb at the shoulder.
Jul 7, 2020 · The supraspinatus muscle is a rotator cuff muscle located in the shoulder, specifically in the supraspinatus fossa, a concave depression in the rear portion of the scapula, or shoulder...
Mar 22, 2024 · The Supraspinatus muscle is located in the upper back, situated in the supraspinous fossa, a shallow depression on the dorsal surface of the scapula (shoulder blade) above its spine. Its tendon passes laterally to insert into the greater tubercle of the humerus, just above the shoulder joint.
May 5, 2023 · The supraspinatus holds the humerus in place, resisting the downward pull of gravity on the shoulder joint due to the arm’s weight. The primary antagonists of supraspinatus are infraspinatus, teres minor, latissimus dorsi and pectoralis major .
Dec 26, 2021 · Origin. Supraspinous fossa of scapula. Insertion. Superior facet on greater tuberosity of humerus. Action. Initiates and assists deltoid in abduction of arm and acts with other rotator cuff muscles. Innervation. Suprascapular nerve (C4, C5, C6) Arterial Supply.
Aug 28, 2023 · The supraspinatus muscle, the most superiorly located of the rotator cuff muscles, resides in the supraspinous fossa of the scapula, superior to the scapular spine. The tendon of the muscle extends laterally, passing under the acromion process and over the head of the humerus, blending into the glenohumeral joint capsule to insert onto the ...
Anatomy of the Supraspinatus Muscle The supraspinatus muscle is a key component of the rotator cuff, a group of muscles and tendons that stabilize the shoulder joint. Understanding its anatomy and function requires a closer look at its origin, insertion, muscle path, and function.
