The rate at which the heart beats is pulse rate. As the heart pumps blood through the body, the pulse can be felt in some of the blood vessels close to the surface of the skin such as wrist, neck or upper arm. Hence pulse represents tactile arterial palpation. Thus the correct answer is option A.

A normal pulse is regular and strong. Heart rates, and therefore pulse rates (number of beats per minute) change with age and can vary between individuals of the same age.

• Pulse is a pressure wave that travels through the arteries after each ventricular systole.
• Since each heartbeat generates one pulse in the arteries, the pulse rate per minute indicates the heart rate.
• Thus, pulse rate is the same as that of heart rate, between 60 to 100 beats per minute. 

Pulse is a pressure wave that travels through the arteries after each ventricular systole. The pulse can be felt in any artery that lies near the surface of the body. Carotid artery (neck region), radial artery (forearm) and femoral artery (legs) all of them are situated near the surface of the body. Thus pulse can be palpated from all of them.

The arteries are superficial at some points in the body. In these places, the heart beat is felt as pulses like the radial, brachial pulse. 

The heart is pumping organ of human body and is situated in the thoracic cavity in the space between two lungs which is known as mediastinum. Heartbeat is rhythmic contraction and relaxation of heart muscles is called as a heart beat. Heart rate is the speed of heart beat measured by a number of contraction of the heart per minute. There is no term like heart stroke. When the blood vessel supplying blood to the brain are clogged it is known as brain stroke. Thus the correct answer is C.

The stethoscope is an acoustic (hearing) medical device used for auscultation(listening of internal sounds of the body. The doctor will place a small metal circle called a bell (hallow disc) or diaphragm (plastic disc), against the chest, at the spot where a person can feel the heartbeat. The stethoscope is composed of rubber tube, earpiece and diaphragm.

The human circulatory system consists of a muscular four-chambered heart, a network of closed branching blood vessels and blood, the fluid which is circulated. The heart is mesodermal in origin. It is situated in the thoracic cavity, in between the two lungs. The rib cage partially encloses and protect chest cavity. In the chest cavity heart and lungs are present. Hence, the heart is protected by the rib cage.
