Pectoralis Major / Pectoralis Major Origin Insertion Innervation Function Kenhub - The clavicular head originates from the anterior border of the medial half of the clavicle (collar bone) while the sternal head arises from the sternum (breast bone) and first through sixth ribs.. The pectoralis major muscle is a large muscle in the upper chest, fanning across the chest from the shoulder to the breastbone. The pectoralis major is a muscle that is situated in the chest region of the human body. Treatment is usually surgical repair when presenting acutely. Beneath the pectoralis major is the pectoralis minor, a thin, triangular muscle. The pectoral region is located on the anterior chest wall.

It can also help move the arm forward or backward. Located deep to the pectoralis major and its covering fascia is another connective tissue layer known as clavicopectoral fascia. The main anterior relation is the pectoralis major muscle, found superficial to the pectoralis minor and almost completely covering it. What is the pectoralis major the pectoralis major also known as the pecs is a large muscle that spans across your chest. The pec major has two large subdivisions, the sternal head, and the clavicular head.

Diagnosis is generally made clinically and is confirmed with mri studies. Injuries to the pec major can involve just the deeper sternal head (partial rupture), or both heads (complete rupture). Found between the two muscles are the lateral pectoral nerve and the pectoral branches of the thoracoacromial artery. Responsible for the movement of the shoulder joint primarily, the pectoralis major has four major actions. In females this important muscle is spread underneath the breast. The pectoralis serves to produce the majority of the pushing motions in the upper body. It's innervated by both medial and lateral pectoral nerves. It makes up the bulk of the chest muscles and lies under the breast.

The pectoralis major is a muscle that is situated in the chest region of the human body.

The pectoralis major is a large muscle connecting from your sternum (chest) and clavicle to your humerus or upper arm bone. The pectoralis major is the muscle that forms the bulk of the chest. What is the pectoralis major muscle? What is the pectoralis major the pectoralis major also known as the pecs is a large muscle that spans across your chest. Together, these muscles are often referred to simply as the 'pecs'. The pectoralis major, pectoralis minor, serratus anterior and subclavius. Lateral lip of intertubercular groove of humerus. The other option is the bicepsbutton™ which can also be used for unicortical fixation but offers the possibility of stitching the. The first option is the arthrex pec button which is a simple suture anchor with needles meant for unicortical fixation. Below this muscle lies the pecoralis minor. The lower/costal fibers pull down the shoulder joint, whereas the upper/clavicular fibers elevate/raise the arm. Illustration of the normal anatomy of the pectoralis major tendon. The main anterior relation is the pectoralis major muscle, found superficial to the pectoralis minor and almost completely covering it.

The pectoralis major tendon forms a characteristic u shape and has anterior (white arrow) and posterior (black arrow) tendon layers that are continuous inferiorly. It consists of a clavicular part and a sternal part, both converging to a flat tendon that inserts on the humerus. Located deep to the pectoralis major and its covering fascia is another connective tissue layer known as clavicopectoral fascia. What is the pectoralis major muscle? A rare acute injury caused by avulsion of the pectoralis major tendon and usually seen in weightlifters.

Found between the two muscles are the lateral pectoral nerve and the pectoral branches of the thoracoacromial artery. The pectoralis major has a broad origin, based on which it is divided into three parts: The bulk of the chest is made up of the pectoralis major which is why it is also called the chest muscle or the pectoral muscle or just 'pecs'. Responsible for the movement of the shoulder joint primarily, the pectoralis major has four major actions. What is the pectoralis major muscle?

The pectoralis serves to produce the majority of the pushing motions in the upper body.

The main anterior relation is the pectoralis major muscle, found superficial to the pectoralis minor and almost completely covering it. Responsible for the movement of the shoulder joint primarily, the pectoralis major has four major actions. It is large and fan shaped, and is composed of a sternal head and a clavicular head. What is the pectoralis major the pectoralis major also known as the pecs is a large muscle that spans across your chest. If you're a gym lover, you'll hear these muscles also being referred to as the pecs muscles. This muscle is particularly active during forward swinging motions of the arm, such as when throwing a ball, batting a ball, swinging a golf club, swinging a tennis racket, and certain swimming strokes. Pec major is the large muscle making up the bulk of the front of the upper chest region. The two pectoralis major muscles, commonly referred to as the 'pecs,'. The sternum (breastbone) and the clavicle (collarbone). It makes up the bulk of the chest muscles and lies under the breast. It is responsible for giving power to the arm in adduction (bringing the arm toward the body), internal rotation (rotating the shoulder toward the body) and flexion of the shoulder joint when the arm is extended. It contains four muscles that exert a force on the upper limb: The pectoralis major has a broad origin, based on which it is divided into three parts:

The pectoralis major has a broad origin, based on which it is divided into three parts: In females this important muscle is spread underneath the breast. Furthermore, the muscle protracts the shoulder. The sternum (breastbone) and the clavicle (collarbone). The pectoralis major is active in deep or forced inspiration, but not expiration. Pec major is the large muscle making up the bulk of the front of the upper chest region. The muscle has two heads: The pectoralis major, pectoralis minor, serratus anterior and subclavius.

It acts on the shoulder and (indirectly on) the scapula, with its most prominent role being the prime mover in shoulder horizontal adduction.

It is responsible for giving power to the arm in adduction (bringing the arm toward the body), internal rotation (rotating the shoulder toward the body) and flexion of the shoulder joint when the arm is extended. A rare acute injury caused by avulsion of the pectoralis major tendon and usually seen in weightlifters. Together, these muscles are often referred to simply as the 'pecs'. It consists of a clavicular part and a sternal part, both converging to a flat tendon that inserts on the humerus. It originates from the breastbone (sternum) and collarbone (clavicle) before attaching into the top of the arm bone (humerus). Pectoralis muscle, any of the muscles that connect the front walls of the chest with the bones of the upper arm and shoulder.there are two such muscles on each side of the sternum (breastbone) in the human body: This muscle is particularly active during forward swinging motions of the arm, such as when throwing a ball, batting a ball, swinging a golf club, swinging a tennis racket, and certain swimming strokes. The pectoralis major, the larger and more superficial, originates at the clavicle (collarbone), the sternum, the ribs, and a tendinous extension. Beneath the pectoralis major is the pectoralis minor, a thin, triangular muscle. Clavicular part, sternocostal part and abdominal part. The pec major is the largest and most superficial of the anterior axioappendicular muscles, lying superficial. In females this important muscle is spread underneath the breast. The clavicular head originates from the front of your collar bone (medial clavicle), then continues down your upper arm bone (humerus) where it attaches at the intertubercular sulcus.

The pectoralis major is the muscle that forms the bulk of the chest pec. The pectoralis major is a muscle that is situated in the chest region of the human body.
