The levator claviculae is an infrequently recognized anatomical variant in humans, distinguished from, for example, cervical adenopathy or a thrombosed vein, but a normal muscle in lower mammals and anthropoids. In humans, when present, it often appears unilaterally, most commonly on the left side, or bilaterally. [4]
The left supraclavicular nodes are the classical Virchow's node because they receive lymphatic drainage of most of the body (from the thoracic duct) and enters the venous circulation via the left subclavian vein. The metastasis may block the thoracic duct leading to regurgitation into the surrounding Virchow's nodes.
What causes lower left abdominal pain? Lower left abdominal pain can have many causes, ranging from minor to serious, says Andrew Boxer, M.D., gastroenterologist of Gastroenterology Associates of ...
The clavicle, collarbone, or keybone is a slender, S-shaped long bone approximately 6 inches (15 cm) long [1] that serves as a strut between the shoulder blade and the sternum (breastbone). There are two clavicles, one on each side of the body. The clavicle is the only long bone in the body that lies horizontally. [2]
TOS can involve only part of the hand (as in the pinky and adjacent half of the ring finger), all of the hand, or the inner aspect of the forearm and upper arm. Pain can also be in the side of the neck, the pectoral area below the clavicle, the armpit/axillary area, and the upper back (i.e., the trapezius and rhomboid area).
The posterior triangle is crossed, about 2.5 cm above the clavicle, by the inferior belly of the omohyoid muscle, which divides the space into two triangles: an upper or occipital triangle; a lower or subclavian triangle (or supraclavicular triangle)
Sometimes this vessel rises as high as 4 cm. above the clavicle; occasionally, it passes in front of the Scalenus anterior, or pierces the fibers of that muscle. The subclavian vein lies behind the clavicle, and is not usually seen in this space; but in some cases it rises as high as the artery, and has even been seen to pass with that vessel ...
The medial supraclavicular nerves or anterior supraclavicular nerves (nn. supraclaviculares anteriores; suprasternal nerves) cross obliquely over the external jugular vein and the clavicular and sternal heads of the sternocleidomastoideus, and supply the skin as far as the middle line.
