Is clavipectoral fascia deep fascia?
The clavipectoral fascia is a sheet of loose connective tissue which is the deep layer of fascia in the pectoral region. It acts to suspend the floor of the axilla.
Where is the clavipectoral fascia attached?
Traced upward, it splits to enclose the subclavius, and its two layers are attached to the clavicle, one in front of and the other behind the muscle; the deep layer fuses with the deep cervical fascia and with the sheath of the axillary vessels.

What runs through clavipectoral fascia?
The arterial pedicles used for rotation of the pectoralis major muscle are the pectoral branch of the thoracoacromial artery, the lateral thoracic artery, and the superior thoracic artery. These vessels pass through the clavipectoral fascia to enter the muscle on its deep surface.
What is the pectoralis fascia?
The pectoral fascia covers the pectoralis major muscle and continues to cover the adjacent rectus abdominis, serratus anterior, and external oblique muscle. At the upper breast near the second rib, the pectoral fascia tightly connects with the superficial fascia of the breast and it is difficult to dissect bluntly.
What is in the Clavipectoral triangle?
It contains the cephalic vein, and deltopectoral fascia, which is a layer of deep fascia that invests the three structures that make up the border of the triangle. The deltoid branch of the thoracoacromial artery also passes through this triangle, giving branches to both the deltoid and pectoralis major muscles.
What is the axillary fascia?
The axillary fascia is relatively dense, especially in the central third of the shoulder and below the deltoid muscle. It divides at the lateral margin of the latissimus dorsi muscle into two layers, which ensheaths the muscle and are attached posteriorly to the spinous processes of the thoracic vertebrae.
What does fascia mean in anatomy?
Fascia is a thin casing of connective tissue that surrounds and holds every organ, blood vessel, bone, nerve fiber and muscle in place. The tissue does more than provide internal structure; fascia has nerves that make it almost as sensitive as skin.
What is the Subclavius muscle?
The Subclavius muscle is a small, triangular muscle that is located between the first rib and the clavicle. Along with the pectoralis minor and the pectoralis major, the subclavius helps to make up the anterior wall in the axilla.
What is Costocoracoid ligament?
The ligament joining the first rib and coracoid process of the scapula.
What is Costoclavicular ligament?
The costoclavicular ligament, also known as the rhomboid ligament or Halsted’s ligament, is a ligament of the shoulder girdle. It is short, flat, and rhomboid in form. It is the major stabilizing factor of the sternoclavicular joint and is the axis of movement of the joint, especially during elevation of the clavicle.
What is Coracoclavicular ligament?
The coracoclavicular ligament, as described above, serves to connect the clavicle and the coracoid process of the scapula. Its two-component structure allows for proper apposition of the acromion and the clavicle while preventing vertical displacement of the scapula with respect to the clavicle.
