The anterior fibers assist the pectoralis major to flex the shoulder. The anterior deltoid also works in tandem with the subscapularis, pecs and lats to internally (medially) rotate the humerus.
Where is your anterior deltoid?
The anterior deltoid is the front shoulder muscle and is one of the three heads of the deltoids. The others being the lateral and posterior heads. The anterior deltoid serves to raise the arm up overhead and is a prime mover in vertical pushing motions.
What is the function and location of deltoid?
Your deltoid muscles are in your shoulder, which is the ball-and-socket joint that connects your arm to the trunk of your body. Deltoid muscles help you move your arms in different directions. They also protect and stabilize your shoulder joint. Like most other muscles in your body, the deltoids are skeletal muscles.
Where does the anterior deltoid originate and insert?
The deltoid muscle originates from the lateral part of the clavicle (collarbone), as well as the spine and acromion process of the scapula (shoulder blade). From these points of origin, the muscle then travels down the arm and inserts on the deltoid tuberosity of the humerus (long bone of the upper arm).
What movement does the deltoid perform?
Actions. Extends, abducts, laterally rotates, and horizontally extends the arm at the shoulder joint.
How do you work out the anterior deltoid?
1. Anterior Deltoid Raise
- Stand with your feet hip-width apart, holding a dumbbell in each hand with your arms at your sides.
- Keeping your arms straight, slowly lift the weights up directly in front of you to shoulder height with your palms facing each other.
- Lower back down to the starting position and repeat.
What are the major functions of the deltoid muscle?
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.
What is the origin of the anterior deltoid?
The main origin of the deltoid was from the superior surface of the anterior acromion, but muscle and tendinous attachments were also seen on the entire anterior surface of the acromion, its anteroinferior surface and on the whole width of the anterior surface of the clavicle.
What do front raises work?
Front dumbbell raises primarily target the front of the shoulders, known as the anterior deltoid. This muscle is used in shoulder flexion. Front dumbbell raises also work the lateral (side) deltoid and the serratus anterior, along with the upper and lower trapezius, clavicular part of the pectoralis major, and biceps.
Where is my deltoid muscle?
The deltoid muscle is a rounded, triangular muscle located on the uppermost part of the arm and the top of the shoulder. It is named after the Greek letter delta, which is shaped like an equilateral triangle.
