| | Extrusome - Wikipedia, the free encyclopedia |
| | Extrusomes are membrane-bound structures in some eukaryotes which, under certain conditions, discharge their contents outside the cell. | | | nematocysts found in Cnidarian animals may be regarded as extrusomes as well. | | | Notable extrusomes include mucocysts, which discharge a mucous mass sometimes used in cyst formation, and trichocysts, which discharge a fibrous rod. |

| | Extrusomes may be used for protection or prey capture. | | | The nature and function of the granules (kinetosomes, extrusomes) is unknown. | | | In some genera of the cyclotrichs (Askenasia, Rhabdoaskenasia) the oral area is encircled by this structure. |

| | They are longer and much more slender than the scales and may bear prominent beads ("kinetocysts", a structurally distinct type of extrusome). | | | Axopodia are used to capture prey and to move cells along a substrate. | | | Axopodia, unlile the scales, radiate from the cell body at right angles to the cell surface. |

| | New Observations on the Extrusomes of Pseudourostyla cristata (Ciliophora, Hypotrichia) | | | They consist of a bell-shaped electron-dense head and a compact, rod-shaped shaft embedded in fluffy, hyaline material; thus, the extrusomes look like little umbrellas in the light microscope, where only the shaft and the cup can be recognized. | | | Previous investigations showed that the extrusomes of P. |

| | Peniculid - Wikipedia, the free encyclopedia |
| | Typically the body has uniform, dense cilia, which also cover a vestibule preceding the mouth. | | | Extrusomes are characteristically in the form of spindle trichocysts, which release thread-like shafts, and never mucocysts. | | | The oral cilia include peniculi, corresponding to the membranelles of related groups, arranged parallel to the mouth deep in the oral cavity. |

| | In both species the toxicysts are localized perpendicularly to all the left side of the cell and especially in the proboscis, that is the first part to contact the prey. | | | This fine structure was compared with the extrusomes of other predator species. | | | The mucocysts form a continuous layer underneath the cortex while the compact vesicles are spaced in the inner cytoplasm; possibly they both are used after the paralysis of the prey for sticking and drag it to the mouth opening. |

| | As extrusomes, sagittocysts are comparable to nematocysts, colloblasts, rhabdites, and other extrusomes common especially to lower eumetazoans, and the origin of all such extrusomes may correlate with the origin of the eumetazoan gut. | | | Sagittocysts are extrusomes found only in acoel turbellarians. | | | They are needlelike secretory products, on the order of 18-50 µm long and 1-5 µm wide, and consist of a fibrous cortex, a central filament, and an intermediate lucent layer. |
