It can be felt at the neck (carotid artery), at the wrist (radial artery), behind the knee (popliteal artery), on the inside of the elbow (brachial artery), near the ankle joint (posterior tibial artery), and a few other places.Pressure waves move the artery walls, which are pliable; these waves are not caused by the forward movement of the blood. When the heart contracts, blood is ejected into the aorta and the aorta stretches. At this point, the wave of distention (pulse wave) is pronounced but relatively slow-moving (3?6 m/s). As it travels towards the peripheral blood vessels, it gradually diminishes and becomes faster. In the large arterial branches, its velocity is 7?10 m/s; in the small arteries, it is 15?35 m/s. The pressure pulse is transmitted fifteen or more times more rapidly than the blood flow.The term pulse is also used, although incorrectly, to denote the frequency of the he
