What is Costocoracoid ligament?
subclavius muscle, the subclavian tendon, and costocoracoid. ligament. The first rib and insertion of the anterior and middle. scalene muscles form posteromedial border and posterolateral. boundary is formed by upper border or scapula.
What muscles does clavipectoral fascia invest?
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 in the Deltopectoral triangle?
The deltopectoral triangle is a triangular depression formed between the clavicle above, lateral border of the pectoralis major medially and the medial border of the deltoid laterally. This narrow triangular area contains investing layers of the clavipectoral fascia and the cephalic vein on its roof which it pierces.
What is Deltopectoral?
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 a deep fascia?
The clavipectoral fascia is a deep layer of fascia in the pectoral regions that acts to suspend the floor of the axilla. It runs as a loose connective tissue sheet between: laterally: coracoid process of scapula.
Is pectoral fascia deep fascia?

Is clavipectoral fascia deep?
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.
What is Costocoracoid membrane?
Medical Definition of costocoracoid membrane : a strong fascia that ensheathes and extends between the subclavius and pectoralis minor muscles and protects the axillary vessels and nerves.
Is pectoral fascia a deep fascia?
The pectoral fascia originates from the clavicle, but only the deep layer of the pectoral fascia adheres to the clavicular periosteum, whereas its superficial layer continues upwards with the superficial lamina of the deep cervical fascia, which surrounds the sternocleidomastoid and the trapezius muscles.
Which vein runs through the deltopectoral groove?
cephalic vein
In the upper part of the arm, the cephalic vein runs in the deltopectoral groove, where it is accompanied by the deltoid branch of the thoracoacromial artery. It then pierces the clavipectoral fascia to drain into the axillary vein just below the clavicle.
What runs in deltopectoral groove?
The deltopectoral groove is located between the superolateral aspect of the pectoral region and the deltoid muscle. It runs obliquely from superomedial to inferolateral and contains the cephalic vein which at the upper margin of the groove dives deep to pierce the clavipectoral fascia and enter the axillary vein.
