MICROANATOMY

Detailed explanation-1: -Platelets are irregularly shaped fragments of cells that circulate in the blood until they are either activated to form a blood clot or are removed by the spleen. Thrombocytopenia is a condition of low levels of platelets and carries an increased risk of bleeding.

Detailed explanation-2: -Platelets are tiny, irregularly shaped blood cell pieces (called fragments) that play an important role in the making of blood clots. When an injury occurs and a blood clot is needed, the platelets become sticky and help plug the site of the injury.

Detailed explanation-3: -Platelets, or thrombocytes, are small, colorless cell fragments in our blood that form clots and stop or prevent bleeding. Platelets are made in our bone marrow, the sponge-like tissue inside our bones. Bone marrow contains stem cells that develop into red blood cells, white blood cells, and platelets.

Detailed explanation-4: -Thrombocytes, or platelets, are not complete cells, but are small fragments of very large cells called megakaryocytes. Megakaryocytes develop from hemocytoblasts in the red bone marrow. Thrombocytes become sticky and clump together to form platelet plugs that close breaks and tears in blood vessels.

Detailed explanation-5: -Then, platelets adopt an irregular shape thanks to the formation of pseudopods that promote adhesion and spreading on the damaged surface [3]. Cytoskeleton is not only responsible for the shape change associated with platelet activation, but also for maintaining the discoid shape of the resting platelet.
