Platelets also called thrombocytes are membrane bound cell fragments derived from the fragmentation of larger precursor cells called megakaryocytes which are derived from stem cells in the bone marrow. Platelet structure and distribution. Blood is prevented from clotting in the blood vessels by their smoothness and the.

Plātlet the smallest of the formed elements in blood a disk shaped non nucleated blood element with a fragile membrane formed in the red bone marrow by fragmentation of megakaryocytes. Platelets tend to adhere to uneven or damaged surfaces and there are an average of about 250000 per mm3 of blood.

They originate in the bone marrow as pinched off pieces of larger cells. When activated these cells adhere to one another to block the flow of blood from damaged blood vessels. Platelets contain no nuclei and are formed in the bone marrow from precursor cells called megakaryocytes.

Abciximab a glycoprotein iibiiia receptor antagonist is a platelet aggregation inhibitor mainly used during and after coronary artery procedures like angioplasty to prevent platelets from sticking together and causing thrombus blood clot formation within the coronary artery. Platelets also called thrombocytes from greek θρόμβος clot and κύτος cell are a component of blood whose function along with the coagulation factors is to react to bleeding from blood vessel injury by clumping thereby initiating a blood clot. Although much more numerous 150000 to 400000 per cubic millimetre than the white cells they occupy a much smaller fraction of the volume of the blood because of their relatively minute size.
