The deltoid muscle is located on the outer aspect of the shoulder and is recognized by its triangular shape. The deltoid is attached by tendons to the skeleton at the clavicle (collarbone), scapula (shoulder blade), and humerus (upper arm bone).
The Deltoid is a three-headed muscle that caps the shoulder. The three heads of the Deltoid are the Anterior, Lateral, and Posterior. All three Deltoid heads attach to the humerus. The Anterior and Lateral heads originate on the collar bone, while the Posterior head originates on the scapula The deltoid is attached by tendons to the skeleton at the clavicle (collarbone), scapula (shoulder blade), and humerus (upper arm bone). The deltoid is widest at the top of the shoulder and narrows to its apex as it travels down the arm. Contraction of the deltoid muscle results in a wide range of movement of the arm at the shoulder due to its location and the wide separation of its muscle fibers.... Click to read more below. The deltoid muscle is a rounded, triangular muscle located on the uppermost part of the arm and the top of the shoulder.  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. 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. The Deltoid Muscles (also known as Deltoids or Delts for short) are a group of triangular muscles which most people would recognize as the shoulder muscles and are located on top of the common shoulder joint for the Scapula, Clavicle and Humerus. 3.The posterior division, also known as the posterior deltoid, is located on the backside of the shoulder joint. The Deltoid Muscles consist of three divisions highlighted in this picture. Typically, there is a combination of these divisions which work together to produce specific movements. 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 involved in rotating the shoulder. The deltoid muscle is responsible for the shoulder's rounded shape. The military press strengthens the deltoids, or shoulders muscles, and other muscles of the upper body. Deltoid muscles contain three parts: posterior, anterior and lateral SHARE SHARE TWEET EMAIL. 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 posterior division of the Deltoid muscles (in conjunction with other muscle groups) are responsible for the pulling movements and exercises such as bent-over rows, pull-ups, pull-downs, and movements such as moving the arms from center away from the body. A fine example of the deltoid muscles. 3.The posterior division, also known as the posterior deltoid, is located on the backside of the shoulder joint. The Deltoid Muscles consist of three divisions highlighted in this picture. Typically, there is a combination of these divisions which work together to produce specific movements. The deltoid muscle is the muscle that gives the shoulder its rounded shape. Many mammals have this muscle, as the design is very efficient, and this muscle is responsible for the abduction of the shoulder and some of the rotation of the arm or limb. The deltoid muscle is responsible for the shoulder's rounded shape. The military press strengthens the deltoids, or shoulders muscles, and other muscles of the upper body.
