Which of the following pulses is located in the arm?

The radial pulse is located in the arm and can be felt on the wrist, specifically on the thumb side, where the radial artery runs close to the surface. This artery branches off from the brachial artery, which supplies blood to the arm and forearm.

It is commonly used by healthcare professionals to assess heart rate and circulation due to its accessibility and the ease of palpation. Other pulses mentioned, such as the femoral, popliteal, and posterior tibial, are all found in the lower body. The femoral pulse is located in the groin area, the popliteal pulse is found behind the knee, and the posterior tibial pulse can be felt near the ankle. This anatomical differentiation is essential for understanding where to palpate for specific pulses in clinical practice.
