AXILLARY VEINS Meaning and
Definition
-
Axillary veins are major vessels that serve as conduits for deoxygenated blood from the upper limbs, shoulders, and surrounding structures to the heart. These veins are found in the axillary region, situated in close proximity to the axillary artery, and play a crucial role in the venous drainage of the upper limb.
The axillary veins are formed by the confluence of the brachial veins, basilic vein, and the cephalic vein as they pass through the axilla (armpit). These veins then unite to form a single vein, namely the axillary vein. The axillary vein proceeds upwards, coursing through the axillary region, and ultimately drains into the subclavian vein.
Axillary veins are characterized by their muscular structure, possessing smooth muscle fibers in their walls that help regulate blood flow. They also contain valves, which assist in preventing the backflow of blood and ensuring unidirectional flow towards the heart. These veins receive blood from various structures in the upper limb, including the deep and superficial veins of the arm, forearm, and hand. Notably, the cephalic vein, originating from the lateral aspect of the upper limb, and the brachial veins, which arise from the deep veins of the upper arm, contribute significantly to the formation of the axillary veins.
Understanding the anatomy and function of the axillary veins is vital, as they may serve as potential sites for the administration of intravenous medications, blood transfusions, or the placement of central venous catheters during medical procedures.
