Cortical granules are regulatory secretory organelles (ranging from 0.2 um to 0.6 um in diameter) found within oocytes and are most associated with polyspermy prevention after the event of fertilization. Cortical granules are found among all mammals, many vertebrates, and some invertebrates. Within the oocyte, cortical granules are located along the cortex, the region furthest fro… WebThe granule cells occupy a strategic location in the cerebellum, since they are the only excitatory neurons and relay information coming from the rest of the central nervous system to the entire cerebellar cortex (Fig. 31.1a).Thus, all the operations performed by the cerebellum depend on the elaboration carried out by the granular layer and retransmitted …
