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]
Between muscle relaxations, intramuscular pressure transiently returns to a level below the venous blood pressure. This allows blood from the capillary system to refill the veins until the next contraction. It is postulated that this change in pressure may be great enough to draw blood from the arterial side to the venous side. It is ...
There are three sizes of veins: large, medium, and small. Smaller veins are called venules, and the smallest the post-capillary venules are microscopic that make up the veins of the microcirculation. [2] Veins are often closer to the skin than arteries. Veins have less smooth muscle and connective tissue and wider internal diameters than ...

Medial border of Deltoid muscle [3] (laterally) It contains the cephalic vein , [ 4 ] and deltopectoral fascia, which is a layer of deep fascia that invests the three structures that make up the border of the triangle.
The veins have now become varicose veins, and from this additional blood, they start becoming tortuous, or twisted. This most commonly affects the superficial veins on the surface of legs, since they see high pressures when standing, rather than the deep veins buried inside the muscles.
Vascular nerves (nervi vasorum) are nerves which innervate arteries and veins. The vascular nerves control vasodilation and vasoconstriction, which in turn lead to the control and regulation of temperature and homeostasis. Vasodilator innervation is restricted to the following sites : 1.)
