Platelets are the formed elements of the blood which participate in hemostasis. Platelets are enucleated, discoid fragments which arise from mature megakaryocytes in the bone marrow. Under normal...Springer Berlin HeidelbergEncyclopedia of Molecular Pharmacology...
C. Immature erythrocytes that may still contain fragments of organelles are called reticulocyte Also called white blood cells: 1. Thrombocytes 2. Erythrocytes 3. Platelets 4. Leukocytes All formed elements found in blood arise from which of the following: ...
Question: Platelets ___ a. have multiple nuclei b. are the precursors of leukocytes c. have a life span of about 120 days d. stick to the damaged area of a blood vessel and help seal the break Formed Elements in Blood: The formed elements in blood are all the various cell types and...
Platelets are formed by fragmentation of the cytoplasm of the megakaryocyte; they contain no nucleus and not long ago were thought to be rather primitive structures. In fact they are highly differentiated and specialized cellular elements. This is indicated by their intricate subcellular structure (for...
Or thrombocyte; a disk-shaped structure, 2 to 4 m in diameter, found in the blood of mammals and important for its role in blood coagulation; platelets lack a nucleus and DNA but contain active enzymes and mitochondria. They are the smallest of the formed elements in blood with a very...
IN THE past two decades, a body of evidence has accumulated to suggest that the formed elements of the blood may play roles in a variety of disease states other than those usually considered to be hematologic diseases. Thus, a role for the platelet in atherogenesis has become accepted,and th...
white blood cells, and platelets are collectively called formed elements. The formed elements constitute 40% to 50% of total blood volume. Red blood cells constitute more than 99% of the formed-element volume, while the rest (less than 1% of total formed element volume) constitute both white...

The development of thrombosis involves 4 main factors: the vessel wall, the formed elements of the blood, blood coagulation, and blood flow. In venous thrombosis the dominant mechanism is blood coagulation. In arterial thrombosis, however, the major part in both the initiation and growth of throm...
