Phlebotomy Technician Practice Exam (NCPT/CPT)

The antecubital fossa is a small triangular depression on the front of the elbow, marked by the tendons of the biceps and brachioradialis muscles. It is most commonly used for drawing blood or inserting IVs because it contains several important blood vessels close to the surface of the skin. The other options may be confusing because they also contain bends or depressions on the limbs, but they are not specifically located at the elbow joint where the antecubital fossa is found. Therefore, they are incorrect choices.
