Resting platelet. Coloured transmission electron micrograph (TEM) of sectioned platelets at rest. A platelet (thrombocyte) is a small cell found in the blood that does not have a nucleus. It plays a major role in blood coagulation,having adhesive properties when activated. It aggregates in a cluster with many other platelets to form a clot and stem bleeding. The discoid shape of resting blood platelets is maintained by a marginal band of microtubules. Magnification: x15,000 when printed at 10 centimetres wide | |
