Why we feel pulse in some parts of the body?

 

Your heart rhythm is used to determine your heart rate, or the number of times your heart beats per minute. When a healthcare provider checks your pulsate, they may also gauge the rhythm and strength of your heartbeat and whether the blood vessel feels hard or soft. The popliteal pulse is one of the pulses you can detect in your body, specifically in the portion of your leg behind your knee. The pulse here is from blood flow to the popliteal artery, a vital blood supply to the lower leg. When plaque hardens, it narrows the arteries and limits the flow of blood to the body, including in your ears, neck or head. This may cause you to hear the characteristic rhythmic thumping or whooshing sound of pulsatile tinnitus in one or both of your ears. You're most likely just feeling your pulse in your abdominal aorta. Your aorta is the main artery that carries blood from your heart to the rest of your body. It runs from your heart, down the center of your chest, and into your abdomen. It's normal to feel blood pumping through this large artery from time to time. The pulse is readily distinguished at the following locations:

(1) At the point in the wrist where the radial artery approaches the surface;

 (2) At the side of the lower jaw where the external maxillary (facial) artery crosses it;

(3) At the temple above and to the outer side of the eye, where the temporal artery is near the      surface;

(4) On the side of the neck, from the carotid artery;

(5) On the inner side of the biceps, from the brachial artery;

(6) In the groin, from the femoral artery;

(7) Behind the knee, from the popliteal artery;

(8) On the upper side of the foot, from the dorsalis pedis artery.

You can feel a pulse in these spots because an artery is running close to the skin and being compressed by a hard structure below. That's why your pulse is often taken at your wrist or neck

When your heart pumps, your body’s arteries expand and contract. That’s your pulsation
