-less than 1%

-Thrombopoiesis

-Megakaryoblast

-Thrombopoietin

-Megakaryocyte

-Proplatelets

-Platelets (thrombocytes)

<h3><u>Explanation</u>;</h3>
  • Platelets (or thrombocytes) make up less than 1% of formed elements with a concentration between 150,000 and 400,000 per cubic millimeter. The production of platelets is called thrombopoiesis.
  • From the myeloid stem cell, a committed cell called a megakaryoblast  is produced. It matures under the influence of thrombopoietin to form a megakaryocyte.
  • Megakaryocytes are easily distinguished both by their large size (about 100 micrometers [μm] in diameter) and their dense, multilobed nucleus. Each megakaryocyte then produces thousands of platelets.
  • The process of how megakaryoctes produce thrombocytes was in question until 2007. Researchers reported that megakaryoctes produce long extension from themselves called proplatelets.
  • While still attached to the megakaryoctye, these proplatelets extreough the blood vessel wall in the red bone marrow. The force from the blood flow "slices" these proplatelets into the fragments we know as platelets (thrombocytes).
