If you are palpating the thumb side of the forearm in the wrist area, what pulse are you checking?

There is no clinically distinct 'humeral pulse' palpated at the wrist; the brachial artery, associated with the humerus, is assessed at the antecubital fossa (inner elbow), not the wrist.

The ulnar pulse corresponds to the ulnar artery, which runs along the medial (little finger/pinky) side of the wrist, opposite the thumb side.

The brachial pulse is located in the antecubital fossa at the elbow and is used for blood pressure measurement, not at the wrist.

The radial artery is a branch of the brachial artery that travels down the lateral (thumb) side of the forearm and becomes superficial and easily palpable just proximal to the wrist on the radial side. It is the most commonly used site for checking peripheral pulse because of its accessibility and the thin tissue overlying it in that location.
