Platelets are derived from cells called:


a. thromboblasts.
b. leukoblasts.
c. megakaryocytes.
d. thrombokaryocytes.

Verified step by step guidance

1. Understand that platelets are small blood components that help in blood clotting.
2. Recognize that platelets are derived from larger cells in the bone marrow.
3. Recall that the correct term for the large bone marrow cells that produce platelets is 'megakaryocytes'.
4. Eliminate options that do not relate to the production of platelets.
5. Identify 'megakaryocytes' as the correct answer from the given options.

Key Concepts

Platelet Production

Platelets, or thrombocytes, are small cell fragments crucial for blood clotting. They are produced in the bone marrow through a process called thrombopoiesis, where large precursor cells called megakaryocytes undergo fragmentation to release platelets into the bloodstream.

Megakaryocytes

Megakaryocytes are large bone marrow cells responsible for the production of platelets. They have a unique structure with a large nucleus and extensive cytoplasm, which allows them to produce thousands of platelets through a process of cytoplasmic shedding.

Thrombopoiesis

Thrombopoiesis is the biological process of platelet formation. It is regulated by thrombopoietin, a hormone produced mainly by the liver and kidneys, which stimulates the production and maturation of megakaryocytes, thereby increasing platelet levels in the blood.
