Clavipectoral triangle
Encyclopedia
The clavipectoral triangle (also known as the deltopectoral triangle) is an anatomical region found in humans and other animals. It is bordered by the following structures:
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 subclavian vein
and the subclavian artery
may be accessed via this triangle, as they are deep to it.
- Pectoralis major muscle
- Deltoid muscleDeltoid muscleIn human anatomy, the deltoid muscle is the muscle forming the rounded contour of the shoulder. Anatomically, it appears to be made up of three distinct sets of fibers though electromyography suggests that it consists of at least seven groups that can be independently coordinated by the central...
- ClavicleClavicleIn human anatomy, the clavicle or collar bone is a long bone of short length that serves as a strut between the scapula and the sternum. It is the only long bone in body that lies horizontally...
It contains the cephalic vein
Cephalic vein
In human anatomy, the cephalic vein is a superficial vein of the upper limb.It communicates with the basilic vein via the median cubital vein at the elbow and is located in the superficial fascia along the anterolateral surface of the biceps brachii muscle.Superiorly the cephalic vein passes...

The subclavian vein
Subclavian vein
The subclavian veins are two large veins, one on either side of the body. Their diameter is approximately that of the smallest finger.-Path:Each subclavian vein is a continuation of the axillary vein and runs from the outer border of the first rib to the medial border of anterior scalene muscle...

Subclavian artery
In human anatomy, the subclavian arteries are two major arteries of the upper thorax , below the clavicle . They receive blood from the top of the aorta...
