ANATOMY

Detailed explanation-1: -Platelets are tiny blood cells that help your body form clots to stop bleeding. If one of your blood vessels gets damaged, it sends out signals to the platelets. The platelets then rush to the site of damage and form a plug (clot) to fix the damage.

Detailed explanation-2: -Platelets are pieces of very large cells in the bone marrow called megakaryocytes. They help form blood clots to slow or stop bleeding and to help wounds heal. Having too many or too few platelets or having platelets that don’t work as they should can cause problems.

Detailed explanation-3: -Thus, platelets resemble cell fragments rather than fully licensed cells. One of the strongest arguments is probably that platelets have no genes to reorganize, because they have no nucleus and supporting DNA material (apart from the mitochondrial genome).

Detailed explanation-4: -Platelets are not true cells, but are in fact cytoplasmic fragments from large cells found in the bone marrow, called megakaryocytes. There are around 150 to 400 thousand platelets in a millilitre of blood, and the are essential for haemostasis.

Detailed explanation-5: -Not only are platelets the cellular mediator of thrombosis, but platelets are also immune cells that initiate and accelerate many vascular inflammatory conditions.
