Which pulse site is found behind the knee?

The pulse site found behind the knee is the popliteal artery. This artery is situated in the popliteal fossa, which is the shallow depression located at the back of the knee joint. It is an important site for pulse palpation because it allows healthcare providers to assess the circulation to the lower leg and foot. By palpating the popliteal pulse, practitioners can gauge the health of peripheral circulation and diagnose possible vascular issues.

The other choices represent different pulse sites: the carotid artery is located in the neck; the brachial artery is found in the arm, usually along the inner elbow; and the dorsal pedis artery is located on the top of the foot. Each of these locations is significant, but they are not found behind the knee, highlighting the unique anatomical positioning of the popliteal pulse.
