Subclavian groove

From WikiMD's Food, Medicine & Wellness Encyclopedia

Subclavian Groove is a notable anatomical feature found in the human body. It is located on the first rib, and serves as a pathway for the subclavian artery and the subclavian vein.

Etymology[edit | edit source]

The term "Subclavian Groove" is derived from the Latin words "sub" meaning under, and "clavis" meaning key. This is in reference to its location beneath the clavicle, also known as the collarbone.

Anatomy[edit | edit source]

The Subclavian Groove is a shallow groove found on the upper surface of the first rib. It extends from the tubercle of the rib to the costochondral junction, and is separated from the scalene tubercle by a ridge. The groove accommodates the subclavian artery and vein, which supply blood to and from the upper limbs.

Clinical Significance[edit | edit source]

The Subclavian Groove is of clinical significance due to its proximity to important vascular structures. Damage to the groove, such as through trauma or surgical procedures, can potentially lead to injury of the subclavian vessels. This can result in serious complications such as hemorrhage or thrombosis.

Related Terms[edit | edit source]

  • Subclavian vein: A major vein of the upper body, draining blood from the head, neck, and arms.
  • First rib: The first and shortest rib of the human rib cage, which provides attachment to several important muscles and houses the subclavian groove.
