What is the purpose of clavipectoral fascia?
What is the purpose of clavipectoral 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.
Which muscles are enclosed by clavipectoral fascia?
The clavipectoral fascia encloses the subclavius muscle located below the clavicle and the pectoralis minor muscle (Fig. 2.10). The upper portion of the clavipectoral fascia, the costocoracoid membrane, is pierced by the cephalic vein, the lateral pectoral nerve, and branches of the thoracoacromial artery.
What is the purpose of Deltopectoral groove?
The deltopectoral groove is an indentation in the muscular structure between the deltoid muscle and pectoralis major. It is the location through which the cephalic vein passes and where the coracoid process is most easily palpable.
Is Clavipectoral fascia deep?
Is Clavipectoral fascia same as deep fascia?
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 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.
Is pectoral fascia a deep fascia?
Which does not pierce Clavipectoral fascia?
The clavipectoral fascia is pierced by the cephalic vein, thoracoacromial artery and vein, lymphatics and lateral pectoral nerve.
What are the three types of fascia?
There are three main types of fascia:
- Superficial Fascia, which is mostly associated with the skin;
- Deep Fascia, which is mostly associated with the muscles, bones, nerves and blood vessels; and.
- Visceral (or Subserous) Fascia, which is mostly associated with the internal organs.
Where does the clavipectoral fascia begin and end?
It courses downwards, deep to the medial border of the pectoralis minor muscle, after which it pierces the clavipectoral fascia. Recall that the clavipectoral fascia represents the deep layer of the pectoral fascia that bridges the space between the clavicle and pectoralis minor muscle.
Where does the clavipectoral branch of the pectoralis minor run?
Discussion. The pectoral branch runs along and around the medial aspect of the pectoralis minor, pierces the clavipectoral fascia, along with the medial and lateral pectoral nerves, and runs inferiorly and obliquely along the deep aspect of the pectoralis major. It is the dominant pedicle of the pectoralis major muscle.
What are the branches of the clavipectoral triangle?
Clavipectoral triangle. The deltoid branch of the thoracoacromial artery also passes through this triangle, giving branches to both the deltoid and pectoralis major muscles. The subclavian vein and the subclavian artery may be accessed via this triangle, as they are deep to it.
Where does the fascia wrap around the pectoralis?
Fascia typically wraps around muscles and divides them into individual compartments. Immediately beneath the fascia covering the deep or innermost surface of the pectoralis major is the clavipectoral fascia.
