MICROANATOMY

Detailed explanation-1: -For a manual blood pressure measurement, the care provider places a stethoscope over the major artery in the upper arm (brachial artery) to listen to blood flow. The cuff is inflated with a small hand pump. As the cuff inflates, it squeezes the arm. Blood flow through the artery stops for a moment.

Detailed explanation-2: -The brachial artery is the main vessel supplying blood to the muscles in your upper arm and elbow joint. It’s often used to measure your blood pressure. The brachial artery is near the surface of your skin, so it’s susceptible to damage from traumatic injuries like arm fractures.

Detailed explanation-3: -The brachial artery is the extension of the axillary artery starting at the lower margin of the teres major muscle and is the major artery of the upper extremity. The brachial artery courses along the ventral surface of the arm and gives rise to multiple smaller branching arteries before reaching the cubital fossa.

Detailed explanation-4: -The blood pressure cuff is placed on the subject’s right arm, allowing 1 inch between the bottom of the cuff and the crease of the elbow. The brachial pulse is palpated just above the angle of the elbow (the “antecubital fossa").

Detailed explanation-5: -Blood travels from the heart into the subclavian artery which continues on down the arm as the axillary artery. The axillary artery travels deep in the arm pit and gives off several small branches which feed muscles and bones around the shoulder. The axillary artery continues down the arm as the brachial artery.
