CHEST MUSCLES ANATOMY


CHEST ANATOMY


Chest muscles can be divided into 3 separate parts

Ø The Pectoral Major

Ø The Pectoral Minor

Ø The Anterior Serratus




THE PECTORAL MAJOR



The Pectoralis major is a thick, fan-shaped muscle, situated at the chest (anterior) of the human body. It contributes maximum part of whole chest .Workout Targeting the Pectoral Major develops a amazing  toned up chest muscles .
Pectoralis major muscle tears are an uncommon sporting injury, most commonly seen in Power lifters, wrestlers, rugby and American football players. The injury is characterized by pain in the chest wall and loss of strength of the muscle.


AREA : The attachment of the cartilage of the sixth or seventh rib








THE PECTORAL MINOR


The Pectoralis minor is a thin, triangular muscle, situated at the upper part of the chest, beneath the Pectoralis major in the human body.It doesn’t contribute much part of the chest but for complete and good shape of chest, its training must not be neglected. You can exercise it without much additional effort because nearly every workout that engages the Pectoralis major also works the Pectoralis minor.


AREA: It arises from the upper margins and outer surfaces of the third, fourth, and fifth ribs.









THE ANTERIOR SERRATUS



The Anterior Serratus inserts along the entire anterior length of the medial border of the scapula(shoulder blades).It basically aids in the upward movement of our. The Anterior Serratus is occasionally called the "big swing muscle" or "boxer's muscle" because  it is largely responsible for the protraction of the scapula — that is, the pulling of the scapula forward and around the rib cage that occurs when someone throws a punch.

The Anterior Serratus also plays an important role in the upward rotation of the scapula, such as when lifting a weight overhead. It performs this in synchronous with the upper and lower fibers of the trapezius muscles.
  


AREA: It originates by nine or ten slips from either the first to ninth ribs or the first to eighth ribs.
