What passes through 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 inside 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 passes through 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 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.
Which vein is present in clavipectoral fascia?
cephalic vein
The clavipectoral fascia is pierced by the cephalic vein, thoracoacromial artery and vein, lymphatics and lateral pectoral nerve.
What does deltopectoral mean?
Deltopectoral definition Filters. (anatomy) Of or pertaining to both the deltoid muscle and the pectoralis major.
What vein is in the deltopectoral groove?
the 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.
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.
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.
What is infraclavicular region?
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.
What is epigastric fossa?
The slight depression in the midline below the sternum. pit of the stomach.
Is cephalic vein in the deltopectoral groove?
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.
What piercing is clavipectoral fascia?
The clavipectoral fascia is pierced by the cephalic vein, thoracoacromial artery and vein, lymphatics and lateral pectoral nerve.
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 is the infraclavicular lymph node?
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 meant by fossa?
Definition of fossa (Entry 1 of 2) : an anatomical pit, groove, or depression.
What is the function of epigastric fossa?
Clinical significance. The epigastrium is the part of the abdomen where abdominal thrusts (the Heimlich manoeuvre) are able to produce a rapid and forceful exhalation of breath.
What is the clavipectoral fascia?
Clavipectoral fascia. Below this it is thin, and at the upper border of the pectoralis minor it splits into two layers to invest the muscle; from the lower border of the pectoralis minor it is continued downward to join the axillary fascia, and lateralward to join the fascia over the short head of the biceps brachii . The coracoclavicular fascia…
What is the cingulate sulcus?
[edit on Wikidata] The cingulate sulcus is a sulcus (brain fold) on the cingulate cortex in the medial wall of the cerebral cortex.
What is the evolution of the central sulcus?
The evolution of the central sulcus is theorized to have occurred in mammals when the complete dissociation of the original somatosensory cortex from its mirror duplicate developed in placental mammals such as primates, though the development did not stop there as time progressed the distinction between the two cortices grew.
What is another name for the central sulcus?
Anatomical terms of neuroanatomy. The central sulcus is a sulcus, or fold, in the cerebral cortex in the brains of vertebrates. Also called the central fissure, or the fissure of Rolando or the Rolandic fissure, after Luigi Rolando.
