Inside the cubital fossa, the median nerve passes medial to the brachial artery. Ulnar nerve is not a content of the cubital fossa. The brachial pulse may be palpated in the cubital fossa just medial to the tendon. The brachial artery continues to the cubital fossa in the anterior compartment of the arm. It lies in the cubital fossa superficial to the bicipital aponeurosis. Near the elbow, it forms the lateral limit of the cubital fossa, or elbow pit. The cubital fossa is clinically important for venepuncture and for blood pressure measurement. Damage to or deformity of the elbow joint increases the risk of cubital tunnel syndrome. This protection is important during venipuncture (taking blood) from the median cubital vein. The anal vein A merges with the cubital vein Cu (female) or terminates freely (male). There exists a fair amount of variation of the median cubital vein. The same splitting of the hindwing cubital vein has analogous terms bifine, trifine, and quadrifine. This results in the cubital vein appearing to have four branches. Another measure was the "cubit" (from "cubital").
