Which artery is located in the upper arm and can be palpated near the elbow?

• A. Radial Artery
• B. Brachial Artery
• C. Femoral Artery
• D. Carotid Artery

Answer: (B)

The brachial artery is the major blood vessel of the upper arm, making it the correct choice for this question. It supplies blood to the arm and is significant in both clinical and emergency settings.

In terms of palpation, the brachial artery can be easily felt just above the elbow joint at the antecubital fossa, the crease of the arm that bends when you flex your elbow. This location is clinically relevant because it is commonly used for blood pressure measurements and venous access points.

The radial artery, while also an important artery in the arm, is located further down near the wrist and is primarily accessed for pulse measurement. The femoral artery is located in the thigh and pelvis region and is not relevant to the upper arm, while the carotid artery is located in the neck and is associated with blood supply to the head and brain. These arteries serve different regions and are not palpated at the elbow, highlighting the unique position of the brachial artery in the upper arm region.
