The deltoid muscle is the muscle forming the rounded contour of the human shoulder. ... The anterior deltoid also works in tandem with the subscapularis, pecs and lats to internally ... An important function of the deltoid in humans is preventing the dislocation of the humeral head when a person carries heavy loads.


The deltoid is the large muscle that covers your shoulder joint. The muscle consists of three fiber groups: the anterior, lateral and posterior deltoids. The anterior deltoid, also known as the front delt, connects the collarbone to the humerus, the large bone of the upper arm.


The anterior, or clavicular, fibers of the deltoid muscle are active during flexion at the glenohumeral joint, for example to swing the upper arm forward during walking or running motions. These fibers are also active during internal/medial rotation of the glenohumeral joint.


The bands merge together as they approach the insertion point on the deltoid tuberosity of the humerus. The deltoid has three distinct functions that correspond to the three bands of muscle fibers. Contraction of the anterior fibers flexes and medially rotates the arm by pulling the humerus towards the clavicle.


The deltoid muscle is constructed with three main sets of fibers: anterior, middle, and posterior. These fibers are connected by a very thick tendon and are anchored into a V-shaped channel.


Deltoid Muscle - Anterior and Middle Heads. The Deltoid muscle (derived its name from the Greek letter delta) is a large, triangular muscle occupying the upper arm and the shoulder giving it this rounded shape. The deltoid consists three sets of fibers: anterior, middle, and posterior.


The anterior deltoid originates at your clavicle, runs down your shoulder and ends at your humerous, or upper arm bone. The main function of the anterior deltoid is shoulder flexion -- lifting your arm up and to the front of your body.


Deltoid receives its blood supply from the posterior circumflex humeral artery. Function. An important function of deltoid is the prevention of subluxation or even dislocation of the head of the humerus particularly when carrying a load. Deltoid is the prime mover of shoulder abduction. Video


The anterior deltoid (L. anterior, before, in front of ; deltoides, triangular) refers to the front head of the deltoid muscle. This part of the delt is responsible for shoulder flexion. Classified as part of the scapulohumeral (intrinsic shoulder) muscle group, the anterior deltoid is situated medial to the lateral deltoid and lateral to the clavicular head of the pectoralis major.


Anterior Deltoid Anterior means front and therefore the anterior deltoid is the part of the deltoid at the front of your shoulder. This part of the deltoid attaches to your collarbone.
