The radial artery is the major artery in the forearm and is palpable at the wrist on the thumb side.

Focus on location and function. The radial artery runs along the lateral (thumb-side) forearm and is one of the main arteries supplying the forearm and hand. It originates from the brachial artery and continues to the wrist where a strong radial pulse can be felt on the thumb side. This combination—being the major artery in the forearm and being palpable at the wrist on the thumb side—best fits the description given. Other statements point to arteries in other regions (the neck or the thigh) or only mention the wrist without recognizing its forearm role, so they don’t match as well.
