Arcus Venosus Palmaris Superficialis
The superficial palmar arch is accompanied by a pair of venae comitantes which constitute the superficial palmar venous arch. It receives the veins corresponding to the branches of the superficial arterial arch: the common palmar digital veins The palmar digital veins (or volar digital veins) on each finger are connected to the dorsal digital veins by oblique intercapitular veins. Some sources distinguish between the "proper palmar digital veins", which are more distal, and the "commo .... References Veins of the upper limb {{circulatory-stub ...

Ulnar Vein
In anatomy, the ulnar veins are venae comitantes for the ulnar artery. They mostly drain the medial aspect of the forearm. They arise in the hand and terminate when they join the radial veins to form the brachial veins. They follow the same course as the ulnar artery.

Superficial Palmar Arch
The superficial palmar arch is formed predominantly by the ulnar artery, with a contribution from the superficial palmar branch of the radial artery. However, in some individuals the contribution from the radial artery might be absent, and instead anastomoses with either the princeps pollicis artery, the radialis indicis artery, or the median artery, the former two of which are branches from the radial artery. Alternative names for this arterial arch are: superficial volar arch, superficial ulnar arch, arcus palmaris superficialis, or arcus volaris superficialis.Again, ''palmar'' and ''volar'' may be used synonymously, but ''arcus volaris superficialis'' does not occur in the TA, and can therefore be considered deprecated. The arch passes across the palm in a curve (Boeckel's line) with its convexity downward, If one were to fully extend the thumb, the superficial palmar arch would lie approximately 1 cm distal from a line drawn between the first web space to the Hook of H ...

Venae Comitantes
Vena comitans is Latin for accompanying vein. It refers to a vein that is usually paired, with both veins lying on the sides of an artery. They are found in close proximity to arteries so that the pulsations of the artery aid venous return. Because they are generally found in pairs, they are often referred to by their plural form: venae comitantes. Venae comitantes are usually found with certain smaller arteries, especially those in the extremities. Larger arteries, on the other hand, generally do not have venae comitantes. They usually have a single, similarly sized vein which is not as intimately associated with the artery. Examples of arteries and their venae comitantes: * Radial artery and radial veins * Ulnar artery and ulnar veins * Brachial artery and brachial veins * Anterior tibial artery and anterior tibial veins * Posterior tibial artery and Posterior tibial veins * Fibular artery and Fibular veins Examples of arteries that do not have venae comitantes (i.e. thos ...
