	The '''~~Marginal Vein~~''' is a ~~superficial~~ vein that is ~~not always present~~ in the ~~human~~ body. It is ~~also known as the '''Vein~~ of ~~Servelle'''. This vein is typically found in~~ the ~~upper limb~~ and ~~runs along the radial margin of~~ the ~~forearm when~~ the ~~palm is facing forward~~.		The '''marginal vein''' is a [[vein]] that is located in the [[limbs]] of the body. It is part of the [[venous system]] and plays a role in the [[circulatory system]] by helping to return [[deoxygenated blood]] back to the [[heart]].

	==~~Structure~~==		== Anatomy ==
	The ~~Marginal Vein, when present, originates from the dorsal venous network of the hand. It then ascends~~ along the ~~radial side~~ of the ~~forearm and drains into~~ the [[~~Cephalic Vein~~]] ~~near the elbow~~. It is ~~a superficial~~ vein, ~~meaning it~~ is ~~close to~~ the ~~surface of~~ the body.		The marginal vein is typically found along the edges of the [[limbs]], particularly in the [[lower limb]]s. It is often associated with the [[great saphenous vein]] in the leg, which is the longest vein in the human body. The marginal vein can vary in size and prominence among individuals.

	==~~Clinical Significance~~==		== Function ==
	The ~~Marginal Vein can be used for venipuncture,~~ the ~~process~~ of ~~obtaining intravenous access for~~ the ~~purpose~~ of ~~intravenous therapy or for~~ blood ~~sampling. However~~, ~~due~~ to ~~its variable presence, it is not always a reliable site for venipuncture~~.		The primary function of the marginal vein is to assist in the drainage of blood from the [[superficial tissues]] of the limbs. It collects blood from smaller [[superficial veins]] and channels it into larger veins, such as the great saphenous vein, which then transport the blood back to the heart.

'''Marginal Vein'''

[[File:Gray's Anatomy plate 587.png|thumb|right|300px|The veins of the right axilla, viewed from in front (marginal vein visible at center)]]

The '''Marginal Vein''' is a superficial vein that is not always present in the human body. It is also known as the '''Vein of Servelle'''. This vein is typically found in the upper limb and runs along the radial margin of the forearm when the palm is facing forward.

==Structure==
The Marginal Vein, when present, originates from the dorsal venous network of the hand. It then ascends along the radial side of the forearm and drains into the [[Cephalic Vein]] near the elbow. It is a superficial vein, meaning it is close to the surface of the body.

==Clinical Significance==
The Marginal Vein can be used for venipuncture, the process of obtaining intravenous access for the purpose of intravenous therapy or for blood sampling. However, due to its variable presence, it is not always a reliable site for venipuncture.
