Golgi complex and secretory granules

摘要: This chapter discusses Golgi complex and secretory granules. In ultrathin sections, the presents itself as stacks of flattened sacs or saccules associated vacuoles vesicles. The functions are many varied. Its involvement in processes had long been suspected by light microscopists because prominence this organelle such cells presence droplets region. is composed three basic elements, most characteristic part being a stack ends which often slightly dilated. occasionally straight but markedly curved on occasions.
