INNOMINATE VEINS Meaning and
Definition
-
Innominate veins, also known as brachiocephalic veins or vena anonyma, are a pair of large veins located in the upper thoracic region of the body. The term "innominate" originates from the Latin word "innominatus," meaning "nameless" or "anonymous." These veins are called as such because they were initially referred to as the "unnamed veins" due to their unique and distinct structure.
The innominate veins are formed by the merging of the internal jugular veins and the subclavian veins on each side of the body. They are responsible for draining the deoxygenated blood from the upper extremities, head, and neck region and transporting it back to the right atrium of the heart.
Each innominate vein is approximately 2-3 centimeters in length and is formed at the level of the first rib. These veins run parallel to the brachiocephalic arteries and are located within the superior mediastinum, behind the superior vena cava.
The right innominate vein is slightly longer than the left innominate vein due to the anatomical positioning of the right and left respective jugular and subclavian veins. The innominate veins play a crucial role in maintaining proper blood circulation and contributing to the overall function of the cardiovascular system.

Etymology of INNOMINATE VEINS
The term "innominate veins" is composed of two words: "innominate" and "veins".
The word "innominate" is derived from the Latin word "innominatus", which is a combination of "in-" (meaning "not") and "nominatus" (meaning "named" or "known"). In this context, "innominate" refers to something that does not have a specific name or designation.
The word "veins" comes from the Old English word "fæne", which later evolved into "veine". It is derived from the Latin word "vena", which means "a blood vessel".
Therefore, "innominate veins" refers to the veins that do not have a specific or rather acknowledged designation.
