Deltoid muscle In human anatomy, the deltoid muscle is the muscle forming the rounded contour of the shoulder. Anatomically, it appears to be made up of three distinct sets of fibers though electromyography suggests that it consists of at least seven groups that can be independently coordinated by the central nervous system.t is also known as the common shoulder muscle, particularly in other animals such as the domestic cat. Deltoid is also further shortened in slang as  delt . A study of 30 shoulders revealed an average mass of 191.9 grams (6.77 oz) (range 84 grams (3.0 oz)–366 grams (12.9 oz)) in humans.

Deltoid Muscle The deltoid moves and stabilizes the shoulder joint. The movements of the different deltoid parts can interact both synergistically and antagonistically depending on the specific part and the position of the humerus. The deltoid is the most important abductor of the shoulder joint. The abduction is mainly initiated and held by the acromial part. Both the clavicular and spinal parts function as adductors up to 60° and abductors over 60°.

What Do Deltoids Move? The upper part of the deltoid muscle attaches to the lateral, or outermost, part of the clavicle and the spine of the scapula, which is a large ridge running across the shoulder blade. The lower part of the deltoid attaches to the deltoid tuberosity, which is a bony bump on the upper portion of the humerus.

The lower part of the deltoid attaches to the deltoid tuberosity, which is a bony bump on the upper portion of the humerus.The deltoid is divided into three parts: anterior (front), middle and posterior (back). Each part moves the arm, but in different directions.he posterior part of the deltoid moves the arm in the opposite direction of the anterior deltoid. It extends and laterally rotates the arm. You extend your arm when you move it straight behind you, and you laterally rotate your arm when you turn the front of the arm bone away to the side.

Deltoid Deltoid. The deltoid muscle is located on the outer aspect of the shoulder and is recognized by its triangular shape. The deltoid muscle was named after the Greek letter Delta due to the similar shape they both share. 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. This channel housed in the shaft of the humerus bone in the arm.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 and injury to the humerus when carrying heavy loads.he deltoid muscle is constructed with three main sets of fibers: anterior, middle, and posterior.

What Muscles Produce Shoulder Flexion? The biceps brachii muscle splits into two tendons at the shoulder: the long head and the short head. The long head of the biceps muscle assists other muscles with shoulder flexion. It is located in the front of the upper arm and attaches to the glenoid fossa, or socket part of the shoulder joint.The long head of the biceps muscle is innervated by the musculocutaneous nerve.he deltoid muscle is composed of three parts: anterior, middle and posterior. The anterior deltoid muscle is located on top of the shoulder and originates on the collarbone. The anterior deltoid tendon attaches to the front of the humerus producing shoulder flexion.
