Platelet Structure and Function

  • Derek Ogston

Abstract

Normal human blood contains some 150,000 to 400,000 platelets per microliter. They circulate as anucleate discs two to five microns in diameter: detailed measurements of a number of parameters of normal platelets have been provided by Stahl and associates (1978). When examined by light microscopy platelets appear to consist of organelles randomly distributed or clumped together in a water-clear cytoplasm (hyaloplasm) enclosed by a membrane. Details of the ultrastructure of platelets have been revealed by electron microscopy studies and have provided information which helps to explain platelet behavior in the process of hemostasis. A diagrammatic representation of platelet structure is provided in Figure 2.1.
