What is the front arm?

The front arm refers to the structures forming the front of the shoulder joint and the muscles acting on this joint. Also known as the glenohumeral joint, the shoulder is located, where the head of the humerus at the top of the arm encounters gllenoid fossils, a cavity similar to the drawer in the upper outer of the shoulder or shoulder blade. Another bone, which is important for the front arm, is the collarbone or collarbone that laterally intersects the upper chest to meet the acromion, one of the two projections of the upper part of the shoulder, only adjacent to the glenohumeral joint. Several main bonds of the front arm hold these bones together, including those that combine collar bones, with two blades that combine scapular processes with each other, and those that connect the shoulder with humerus. The front arm muscles include front deltooid and pectoralis major, which are muscles that move the arm that will bring the arm in front of the body.

alkkolMost of the bone of each shoulder blade is located at the upper back behind the rib cage, the upper outer part of the shoulder is designed outwards and forward to form part of the front arm. It does this through two irregularly shaped projections: Acromion and Coracoid processes. The acromion process is the top of the shoulder joint, and the corocoid process is found medium or inside the shoulder joint, just below the collar bones on the front of the shoulder. Together with the side end of the collarbone, two processes form and the ligaments between them are a triangle, which is only middle to the glenohumeral joint on the front arm.

The glenohumeral joint itself is the joint of the balls and cut, where the arm meets the torso. Includes the humeral head and gllenoid fossu, which is located on the top of the outer aspect of both shoulder blades, with a head inserted into the fossa like a ball into a cup. Structures covering the anterior aspect of this joint are capsular ligaments closing the joint capsule. They spread laterally from the neck of the shoulder blade on its frontside to the neck of Humer's bone on the same side.

above or better than capsular bonds are the crowns that run parallel to capsular ligaments and combine the corocoid process of the shoulder blade to the top of the humerus bones. Crossing the space above Coracohumeral ligaments are coromial ligaments that run up and out from the Coracoid process to the acromion process. Similar links are associated with acromion with the side end of the collarbone and a corocoid with the outer third of the collarbones directly above it.

Superficial for this triangle of the shoulder bonds are the main muscles of the front arm, which allow the shoulder to move forward from Attaching to the collarbone and pulling on the humerus. The anterior deltooid is the front of the deltooid muscle that extends from the outer third of the collarbone to the side aspect of Humer's bone about in the middle of the upper arm. Next to the front deltooid in the chest is the pectoralis major, which runs from the inner half of the collarbone through the front arm to the niche on the front of the humerus bone called intertubercular groove.
