The deltoid muscle is the muscle forming the rounded contour of the human shoulder. It is also known as the 'common shoulder muscle', particularly in other animals such as the domestic cat. Anatomically, the deltoid muscle is made up of three distinct sets of muscle fibers, namely the anterior or clavicular part (pars clavicularis)
Your deltoid muscles cover the top of your shoulder. They help you lift your arm to front, side and back. Deltoid muscle pain can affect swimmers, pitchers or anyone who performs repetitive overhead arm movements.
Deltoid muscle (Musculus deltoideus) The deltoid is a thick, triangular shoulder muscle. It gets its name because of its similar shape to the Greek letter ‘delta’ (Δ). The muscle has a wide origin spanning the clavicle, acromion and spine of scapula.
The Deltoid muscle is a large triangular-shaped muscle that lies over the glenohumeral joint and which gives the shoulder its rounded contour. It is comprised of three distinct portions (anterior or clavicular, middle or acromial, and posterior or spinal)
The deltoid muscle is the main muscle of the shoulder. A triangle-shaped muscle, it helps move your upper arm and stabilizes the shoulder joint. The deltoid connects to the clavicle (collarbone), spine of the scapula (shoulder blade), and humerus (upper arm bone).
The deltoid is an intrinsic muscle of the shoulder region. It is shaped like an inverted triangle and can be divided into three parts (anterior, middle and posterior). Attachments: Originates from the lateral third of the clavicle, the acromion and the spine of the scapula.
The 4 rotator cuff muscles—the supraspinatus, infraspinatus, teres minor, and subscapularis—work with the deltoid to stabilize the shoulder and move the upper limb. These muscles initiate abduction from 0° to 15° and stabilize the glenohumeral joint when the deltoid abducts the arm past 15°.
The deltoid muscle is responsible for the brunt of all arm rotation and allows a person to keep carried objects at a safer distance from the body. It is also tasked with stopping dislocation...
