NCCT National Certified Phlebotomy Technician - Exam Topics Sample Questions

Platelets are created in the bone marrow from which of the following?

Correct Answer:
megakaryocytes
platelets, also known as thrombocytes, are small, disk-shaped cell fragments in the blood that are crucial for blood clotting. they play a vital role in preventing excessive bleeding by forming clots in damaged blood vessels. the process of platelet production, primarily occurring in the bone marrow, involves a specific type of large bone marrow cell known as a megakaryocyte.

megakaryocytes are remarkably large cells derived from hematopoietic stem cells in the bone marrow through a process called megakaryopoiesis. this process involves the differentiation and maturation of megakaryocytes under the influence of various growth factors, notably thrombopoietin (tpo). tpo is a hormone produced by the liver and kidneys, which regulates the production of platelets by promoting the growth of megakaryocytes.

as megakaryocytes mature, they undergo a unique process called endomitosis, where they replicate their dna multiple times without actual cell division, resulting in a large, polyploid cell with multiple copies of chromosomes. this characteristic makes megakaryocytes distinct from other cells in the bone marrow. the high dna content enables the megakaryocytes to produce and support large amounts of cellular machinery necessary for the production of platelets.

the final stage of platelet production involves the extension of long, thin, cytoplasmic processes from the megakaryocytes called proplatelets. these proplatelets protrude into the blood vessels running through the bone marrow. as these proplatelets extend and flow along with the bloodstream, shear forces and enzymatic reactions snip them into smaller segments, which then become individual platelets. once released into the circulation, these platelets are ready to fulfill their role in blood clotting and wound repair.

thus, when considering the origin of platelets in the bone marrow, it is clear that megakaryocytes are the sole progenitors. other cells mentioned, such as monocytes, lymphocytes, and polymorphonuclear leukocytes, are involved in different aspects of the immune response and do not contribute to the production of platelets. megakaryocytes are unique in their role as the 'platelet factories' of the hematopoietic system.
