Pectoralis major

pectoralpectoral musclepectoralis major muscle
The pectoralis minor is a thin, triangular muscle, situated at the upper part of the chest, beneath the pectoralis major in the human body.
Beneath the pectoralis major is the pectoralis minor, a thin, triangular muscle.

Coracoid process

coracoidcoracoid processes
The fibers pass superior and lateral and converge to form a flat tendon, which is inserted into the medial border and upper surface of the coracoid process of the scapula.
The horizontal portion is flattened from above downward; its upper surface is convex and irregular, and gives attachment to the pectoralis minor; its under surface is smooth; its medial and lateral borders are rough; the former gives attachment to the pectoralis minor and the latter to the coracoacromial ligament; the apex is embraced by the Conjoint tendon of origin of the coracobrachialis and short head of the biceps brachii and gives attachment to the coracoclavicular fascia.

Clavipectoral fascia

coracoclavicular fascia
The pectoralis minor muscle is covered anteriorly (superficially) by the clavipectoral fascia.
It occupies the interval between the pectoralis minor and subclavius, and protects the axillary vein and artery, and axillary nerve.

Thorax

chestthoracicthoraces
The pectoralis minor is a thin, triangular muscle, situated at the upper part of the chest, beneath the pectoralis major in the human body. The pectoralis minor depresses the point of the shoulder, drawing the scapula superior, towards the thorax, and throwing its inferior angle posteriorly.
The contents of the thorax include the heart and lungs (and the thymus gland); the (major and minor pectoral muscles, trapezius muscles, and neck muscle); and internal structures such as the diaphragm, the esophagus, the trachea, and a part of the sternum known as the xiphoid process).

Shoulder

The pectoralis minor depresses the point of the shoulder, drawing the scapula superior, towards the thorax, and throwing its inferior angle posteriorly.

Thoracoacromial artery

thoracoacromial trunkpectoral branchthoracoacromial
The thoracoacromial artery (acromiothoracic artery; thoracic axis) is a short trunk that arises from the second part of the axillary artery, its origin being generally overlapped by the upper edge of the pectoralis minor.

Medial pectoral nerve

medial pectoralMedial pectoral nerves
The Medial pectoral nerve pierces the pectoralis minor and the clavipectoral fascia.
It then enters the deep surface of the pectoralis minor muscle, where it divides into a number of branches, which supply the muscle.

Scapula

List of movements of the human body

body movements
The major muscles involved in retraction include the rhomboid major muscle, rhomboid minor muscle and trapezius muscle, whereas the major muscles involved in protraction include the serratus anterior and pectoralis minor muscles.

Apical lymph nodes

subclavicular groupapicalApical group
An apical (or medial or subclavicular) group of six to twelve glands is situated partly posterior to the upper portion of the Pectoralis minor and partly above the upper border of this muscle.

Pectoral axillary lymph nodes

Anterior (pectoral) grouppectoral axillary
An anterior or pectoral group consists of four or five glands along the lower border of the Pectoralis minor, in relation with the lateral thoracic artery.

Chicken fingers

Chicken fingers, also known as chicken tenders, chicken goujons, chicken strips, tendies or chicken fillets, are chicken meat prepared from the pectoralis minor muscles of the animal.

Radical mastectomy

Radical mastectomy is a surgical procedure involving the removal of breast, underlying chest muscle (including pectoralis major and pectoralis minor), and lymph nodes of the axilla as a treatment for breast cancer.

(The other two muscles are pectoralis minor and the short head of the biceps brachii.) It is situated at the upper and medial part of the arm.

Axilla

Some sources also include the pectoralis minor.

Radial nerve

From the brachial plexus, it travels behind the third part of the axillary artery (part of the axillary artery distal to the pectoralis minor).

Subclavius muscle

Along with the pectoralis major and pectoralis minor muscles, the subclavius muscle makes up the Anterior Axioappendicular Muscles also known as anterior wall of the axilla.
