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. It is one of the four rotator cuff muscles and also abducts the arm at the shoulder.
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.
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...
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.
Mar 22, 2024 · The Supraspinatus muscle is one of the four rotator cuff muscles in the shoulder, playing a crucial role in stabilizing and moving the shoulder joint. It is particularly involved in abduction of the arm (lifting it away from the body) and helps hold the head of the humerus firmly within the shoulder socket.
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 supraspinatus muscle is one of the rotator cuff muscles. It is a thick, bipennate type of skeletal muscle. It is located: - anterior (deep) to the trapezius muscle and the supraspinous fascia; - posterior (superficial) to the scapula, and the subtendinous bursa of supraspinatus muscle.
May 5, 2023 · Supraspinatus is a small triangular muscle in the upper shoulder region. It is the smallest of the 4 rotator cuff muscle, the other three being the infraspinatus, subscapularis, and teres minor. Anatomy. Location and Attachments.
Nov 14, 2022 · The supraspinatus muscle is one of the rotator cuff muscles which arises from the supraspinous fossa (above the spine of the scapula). Its muscle fibres converge to form a thin tendon which passes beneath the acromion process attaching to the superior facet on the greater tubercle of the humerus. Origin. Supraspinous fossa of scapula. Insertion.
