In medicine, a<unk>  represents the tactile arterial<unk> alpation of the cardiac cycle (heartbeat) by trained fingertips. The<unk>  may be<unk> alpated in any<unk> lace that allows an artery to be compressed near the surface of the body, such as at the neck (carotid artery), wrist (radial artery), at the groin (femoral artery), behind the knee <unk> opliteal artery), near the ankle joint <unk> osterior tibial artery), and on foot (dorsalis<unk> edis artery).<unk>  (or the count of arterial<unk> <unk> er minute) is equivalent to measuring the heart rate. The heart rate can also be measured by listening to the heart beat by auscultation, traditionally using a stethoscope and counting it for a minute. The radial<unk>  is commonly measured using three fingers. This has a reason: the finger closest to the heart is used to occlude the<unk> <unk> ressure, the middle finger is used get a crude estimate of the blood<unk> ressure, and the finger most distal to the heart (usually the ring finger) is used to nullify the effect of the ulnar<unk>  as the two arteries are connected via the<unk> almar arches (superficial and deep). The study of the<unk>  is known as sphygmology.
