MICROANATOMY

Detailed explanation-1: -Platelets are the smallest blood cells, typically around 2m in diameter and anucleated, with an average lifespan of 7 to 10 days in humans.

Detailed explanation-2: -The platelet is a circulating anuclear fragment of a bone marrow megakaryocyte, 3 to 4 m in diameter, with limited synthetic capability.

Detailed explanation-3: -Large platelets have a diameter greater than 4 microns. Giant platelets have a diameter greater than 7 microns (larger than a normal red blood cell). Large platelets can be seen when platelet turnover is increased (as in immune thrombocytopenic purpura).

Detailed explanation-4: -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-5: -Platelets are normally very small in size, though occasionally large or giant platelets may be seen. Platelet anisocytosis refers to a significant variation in the size of platelets on a blood film.
