WebIn order to relate structure to function, the anatomy of the platelet has been divided into several zones [1, 2]. The peripheral zone consists of membranes and closely associated structures providing the surface of the platelet and the walls of the channels making up the surface-connected open canalicular system (OCS) (Figure 1). WebWith few exceptions, platelets of various species contain a plasma membrane, circumfrential microtubular system, mitochondria, alpha granules, dense bodies, glycogen granules, and an open canalicular system. However, ruminant platelets lack an organized microtubular system and an open canalicular system. grafton clock tower
