The "AC" in medical terms commonly refers to the antecubital fossa. This is the small, triangular depression located on the front of the elbow joint. It's often the preferred site for IV insertion because the veins in this area are relatively easy to access. The cephalic vein and the basilic vein are the two primary veins located in the antecubital fossa.
While "AC" is not a specific vein name, it's commonly used as shorthand for the antecubital fossa, making it a convenient reference point for locating veins in this region.
