Platelet, colourless, nonnucleated blood component that is important in the formation of blood clots (coagulation). Platelets are found only in the blood of mammals. Platelets are formed when cytoplasmic fragments of megakaryocytes, which are very large
If you have a higher than typical platelet count, it can be caused by genetic mutations that make your bone marrow produce more platelets. This is called primary thrombocythemia. If it's caused by an underlying disorder that triggers the stem cells in your bone marrow to make more platelet...

A platelet count is a diagnostic test that determines the number of platelets in the patient's blood. Platelets, which are also called thrombocytes, are small disk-shaped blood cells produced in the bone marrow and involved in the process of blood clotting. There are normally between 150,00...

Let us also approximate the thrombus by a ring characterized by its length l=const, and inner radius r(t). This is a rather strong assumption, but it would let us couple the hydrodynamics and thrombus growth and would allow the analytical consideration of the model. Therefore, one may ...
Aplastic anemia is a general term used when the bone marrow fails to produce any blood cells (red cells, white cells, and platelets), also called pancytopenia. This can be caused by some viral infections (parvovirus or HIV), medications (gold, chloramphenicol, phenytoin [Dilantin], valproate ...
