The anatomy of the veins of the heart is very variable, but generally it is formed by the following veins: heart veins that go into the coronary sinus: the great cardiac vein, the middle cardiac vein, the small cardiac vein, the posterior vein of the left ventricle, and the oblique vein of the left atrium (oblique vein of Marshall). Heart veins ...
Vascularity, in bodybuilding, is the condition of having many highly visible, prominent, and often extensively-ramified superficial veins. [1] The skin appears "thin"—sometimes virtually transparent—due to an extreme reduction of subcutaneous fat, allowing for maximum muscle definition. [citation needed]
Superficial veins are important physiologically for cooling of the body. When the body is too hot, the body shunts blood from the deep veins to the superficial veins to facilitate heat transfer to the body's surroundings. Superficial veins are often visible underneath the skin.
Though veins might make it appear as such, human blood is never naturally blue. [3] The blue appearance of surface veins is caused mostly by the scattering of blue light away from the outside of venous tissue if the vein is at 0.5 mm deep or more. Veins and arteries appear similar when skin is removed and are seen directly. [4] [5]
The basilic vein is a large superficial vein of the upper limb that helps drain parts of the hand and forearm. [1] It originates on the medial side of the dorsal venous network of the hand and travels up the base of the forearm, where its course is generally visible through the skin as it travels in the subcutaneous fat and fascia lying superficial to the muscles.
It is formed by smaller superficial veins that merge on the dorsolateral aspect of the penis. It drains the prepuce and the skin of the shaft, and, running backward in the subcutaneous tissue, inclines to the right or left, and opens into the corresponding superficial external pudendal vein, a tributary of the great saphenous vein.

BOSTON - The northern lights have put on a show in 2024. In May, the strongest solar storm in 21 years set off the aurora borealis and on Thursday night, the stunning colors were visible once ...
Vein matching, also called vascular technology, [1] is a technique of biometric identification through the analysis of the patterns of blood vessels visible from the surface of the skin. [2]
