Antecubital Fossa | Anatomy and Structure
Antecubital Fossa Definition
What is Antecubital Fossa? It is a triangular depression on the anterior surface of the elbow. It is bounded by the humerus’s medial epicondyle, the humerus’s lateral epicondyle, and the coronoid of the ulna. It contains several vital structures, including the brachial artery and the median nerve.
The brachial artery is a large blood vessel that supplies blood to the arm and hand. The median nerve is a nerve that supplies sensation to the palm and some muscles in the forearm. It is an important site for accessing these structures.
It can be used for venipuncture to obtain a blood sample or inject medication into the arm. The brachial artery can be accessed by placing a needle into the medial side of the fossa. The median nerve can be accessed by placing a needle into the lateral side of the fossa.
It is also an important site for taking blood pressure readings. The brachial artery can measure blood pressure by placing a cuff around the arm and measuring the pressure in the cuff.
