The term is most often used to describe a [[Secretory_pathway|secretory]] [[Vesicle (biology)|vesicle]]. ==Leukocytes== A group of [[leukocytes]] called [[granulocytes]] contain granules and play an important role in the immune system. The granules of certain cells, such as [[Natural killer cell|Natural Killer Cells]], contain components which can lead to the [[lysis]] of neighboring cells. The granules of [[leukocytes]] are classified as [[azurophilic granules]] or [[specific granules]]. Leukocyte granules are released in response to immunological stimuli during a process known as [[degranulation]]. ==Platelets== The granules of [[platelets]] are classified as [[dense granule]]s and [[Platelet alpha-granule|alpha granule]]s. ==See also== * [[Chromophil|Chromaffin granule]] ==External links== * {{eMedicineDictionary|granule}} * {{eMedicineDictionary|specific+granules}} [[Category:Cell anatomy]] {{cell-biology-stub}} [[de:Granula]] [[nl:Granule]] [[simple:Granule (cell biology)]]
