Where is the antecubital fossa located?

1. Behind the knee

2. On the wrist

3. Bend of arm (elbow)

4. Side of the neck

The correct answer is: Bend of arm (elbow)

The antecubital fossa is located on the bend of the arm, or the crook of the elbow. This is where the brachial artery and median nerve are located, making it a common location for blood draws and intravenous access. A is incorrect because behind the knee is called the popliteal fossa. B is incorrect because the wrist is located on the lower arm, not the bend of the arm. D is incorrect because the side of the neck is called the carotid triangle. Knowing the correct location of the antecubital fossa is important for medical professionals when administering procedures or treatments involving the arm.
