Platelets are blood cells that are released from bone marrow megakaryocytes and circulate for approximately 10 days. They possess granular cytoplasm with no nucleus and their diameter when seen in a Wright-stained peripheral blood film averages 2.5 um with a subpopulation of larger cells, 4–5 um.
What Are Platelets? Function & Anatomy - Cleveland Clinic
2024年8月26日 · Your platelets’ primary function is to stop bleeding if a blood vessel gets damaged. During an injury, platelets cluster together at the site of the wound to act as a plug. They also help seal the blood vessels in a process called clotting (coagulation) to prevent excess blood from leaving your body.
Platelets (Thrombocytes)- Definition, Structure, Immunity, Functions
2022年5月5日 · Platelets or thrombocytes are anucleated cells derived from the megakaryocytic cells in the bone marrow that, besides being one of the key players in maintaining hemostasis, are involved in developing non-hemostatic immune functions.
Physiology, Platelet - StatPearls - NCBI Bookshelf
2023年7月25日 · The monitoring of platelet quantity and function is frequently useful in evaluating the bleeding risk in hospitalized patients. In healthy patients, platelets are incredibly numerous, with a range of 150 to 350 x10/L. A drop in this number can indicate the consumption of platelets by a condition such as disseminated intravascular coagulation ...

Platelet biology and functions: new concepts and clinical
2018年11月14日 · This Review describes current evidence for the heterogeneity in platelet structure, age, and activation properties, with consequences for a diversity of platelet functions.
Platelet - Wikipedia
Platelets or thrombocytes (from Ancient Greek θρόμβος (thrómbos) 'clot' and κύτος (kútos) 'cell') are a blood component whose function (along with the coagulation factors) is to react to bleeding from blood vessel injury by clumping, thereby initiating a blood clot. [1] .
Platelet Structure, Function, and Disorders | SpringerLink
Platelets are derived from bone marrow progenitor stem cells in a process known as thrombopoiesis. During this process, the pluripotent marrow stem cell first undergoes a transformation into a giant cell with a large cytoplasm and a …

2023年8月7日 · In this article, we will consider the structure, function and clinical relevance of platelets. Platelets originate from megakaryocytes, which are the largest progenitor cells of the bone marrow. Megakaryocytes originate from the common myeloid progenitor. They contain two types of granules, namely alpha-granules and dense granules.
Thrombocyte: Anatomy and function - Kenhub
2024年3月4日 · Thrombocytes, also known as platelets, are specialized blood cells which function to controlling blood clotting. Function: Thrombocytes form clots in response to tears in blood vessels by triggering the release of a series of coagulation factors.
