What passes through the 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 structure S pierce the clavipectoral fascia?
The clavipectoral fascia is pierced by the cephalic vein, thoracoacromial artery and vein, lymphatics and lateral pectoral nerve.
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.
Where is the clavipectoral fascia attached?
The clavipectoral fascia extends superiorly from the clavicle, medially from the costochondral joints, and superolaterally from the coracoid process. The fascia converges in the axilla, where it acts as a protective structure over the neurovascular structure of the axilla.
What is Deltopectoral groove?
The deltopectoral groove is an indentation in the muscular structure between the deltoid muscle and pectoralis major. Deltopectoral groove. Deltoid muscle. Pectoralis major. TA2.
What is deltopectoral groove?
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.
What vein is in the deltopectoral groove?
The cephalic vein
The cephalic vein is located in the deltopectoral groove (Fig. 26-12), which is formed by the reflections of the medial head of the deltoid and the lateral border of the greater pectoral muscles. The groove can be precisely located by palpating the coracoid process of the scapula.
Is deltopectoral groove and deltopectoral triangle same?
9.1. It is separated from the deltoid muscle by a groove termed the deltopectoral groove. The deltopectoral groove transitions upward to the infraclavicular fossa (deltopectoral triangle) that can be seen as a small depression inferior to the clavicle.
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.
What is the deltopectoral groove?
What is infraclavicular region?
Medical Definition of infraclavicular : situated or occurring below the clavicle the radiograph showed an opacity in the left infraclavicular area of the chest.
Why do infraclavicular blocks occur?
The infraclavicular brachial plexus nerve block is well suited for the catheter technique because the musculature of the chest wall helps stabilize the catheter and prevents its dislodgement compared with the more superficial location used with the interscalene and supraclavicular approaches to brachial plexus block.
What is infraclavicular?
What is infraclavicular block?
The infraclavicular brachial plexus block provides a block of the arm below the shoulder. Unlike the axillary approach, it can be performed without abduction of the arm, making it useful for patients with limited shoulder mobility.
Is infraclavicular part of brachial plexus?
Surgical Anatomy The infraclavicular brachial plexus includes the cords and the terminal branches. They correlate closely with the axillary artery . The posterior cord is formed by the junction of the posterior divisions of the three trunks; it first runs lateral and then posterior to the axillary artery.
Where are the infraclavicular lymph nodes?
One or two deltopectoral lymph nodes (or infraclavicular nodes) are found beside the cephalic vein, between the pectoralis major and deltoideus, immediately below the clavicle.
What is the clavipectoral fascia?
The clavipectoral fascia is a strong sheet of connective tissue that is attached superiorly to the clavicle and envelops the subclavius and pectoralis minor muscles. The fascia extends from the lower border of the pectoralis minor to become continuous with the axillary fascia in the floor of the axilla.
What structures are in the clavipectoral triangle?
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, and also the cephalic vein in the triangle. The deltoid branch of the thoracoacromial artery also passes through this triangle,…
Where does the pectoralis major muscle attach to the clavicle?
It pierces the clavipectoral fascia medial to the tendon of the pectoralis minor muscle and emerges at the groove between the clavicular and sternocostal heads of the pectoralis major muscle. It then runs in a cephalocaudal direction on the undersurface of the muscle, plastered to it by its fascial envelope.
Is the clavicle innervated by the supraclavicular nerve?
While the cutaneous innervation of the skin above the clavicle is well-known to be supplied by the supraclavicular nerve of the superficial cervical plexus (SCP), the sensory innervation of the clavicle itself is somewhat controversial.
