The term "antecubital fossa" refers to the anatomical region located at the front of the elbow. This triangular-shaped area is an important landmark for both anatomical study and clinical practice, particularly in procedures such as taking blood pressure and venipuncture (the process of inserting a needle into a vein).

The antecubital fossa contains critical structures including major blood vessels such as the brachial artery and the median nerve, which makes it a vital site for medical professionals to access veins for blood sampling or intravenous therapy. Its location and the structures it contains are what emphasize its significance in both anatomy and practical applications in healthcare.
