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]
Deep veins are deeper in the body and have corresponding arteries. Perforator veins drain from the superficial to the deep veins. [16] These are usually referred to in the lower limbs and feet. [17] Superficial veins include the very small spider veins of between 0.5 and 1 mm diameter, and reticular or feeder veins. [18] Venous plexuses
The straight angle between the ovarian vein (or testicular vein in males in the case of varicocoele) and the renal vein has been proposed as a cause of decreased blood return. [citation needed] A related diagnosis is nutcracker syndrome where the left renal vein is described as being compressed between the aorta and the superior mesenteric ...
DVA can be characterized by the caput medusae sign of veins, which drains into a larger vein. The drains will either drain into a dural venous sinus or into a deep ependymal vein. It appears to look like a palm tree. [1]
Veins become more visually prominent when lifting heavy weight, especially after a period of proper strength training. Physiologically, the superficial veins are not as important as the deep veins (as they carry less blood) and are sometimes removed in a procedure called vein stripping , which is used to treat varicose veins .
The pampiniform plexus (from Latin pampinus 'tendril' and forma 'form') is a venous plexus – a network of many small veins found in the human male spermatic cord, and the suspensory ligament of the ovary. In the male, it is formed by the union of multiple testicular veins from the back of the testis and tributaries from the epididymis.
Traditionally, varicose veins were investigated using imaging techniques only if there was a suspicion of deep venous insufficiency, if they were recurrent, or if they involved the saphenopopliteal junction. This practice is now less widely accepted. People with varicose veins should now be investigated using lower limbs venous ultrasonography.
The patient is positioned at a 45° incline, and the filling level of the external jugular vein determined. [1] The internal jugular vein is visualised when looking for the pulsation. In healthy people, the filling level of the jugular vein should be less than 4 centimetres vertical height above the sternal angle. [2]
