Mandible - a maxilla eyisinambuzane. Lokhu siqukethe mouthparts yebhangqa izakhi ezifanayo. Iningi izinambuzane, kanye millipedes kanye ezinamagobolondo mandible ukhona ukugaya ukudla. Nokho, izinambuzane nabantu, kukhona esinye isici kwalesi sakhi - akha izidleke.

umsuka

Mandible - kungcono kuyafana mandibles. Kuyinto emkhawulweni ikhanda izingxenye ukuthi ngesikhathi ukuvela kakhulu ukushintshwa. Kukhona kucatshangwa ukuthi uguqulwa koksopodity futhi endite. Uma is they ayenendawo ezinamagobolondo lasendulo.

Mandibles kukhona izingxenye okuqinile camera we sclera, lapho emabhulashini kanye tine ahlukahlukene. Kubonakala sengathi laba bahlabeleli emva udebe eliphezulu.

Zonke abameleli babe entognatha isici isakhiwo mandible. Banamathele kuphela ngesinye isikhathi ekhanda. Boca ngomlomo wabo thembeke tho ukuba udebe lwangezansi (a side ingxenye yayo). Ngenxa yalokho, emaphaketheni akhiwa. Kuyo abeka umhlathi: kokubili aphansi kanye engenhla. Kungoba kulesi sici, lonke ikilasi wabizwa ngokuthi "entognatha".

Ngo izinambuzane ezinamaphiko schetinohvostok, sihluke kuleli ohlangothini iphuzu ukuhambisana, kukhona eyodwa ngaphezulu. Ngenxa yalesi banayo ithuba lokwenza enamandla futhi ivale abalimi ukunyakaza mandibles.

Zonke sezinambuzane babe mandibles, esezindaweni zawo ukuhambisana nemikhakha umsipha ikhanda ehlukana. Kubalulekile ukunamathela imisipha ezilawula lezi mandibles.

izici obusebenzayo

izinambuzane Mandible ingase yehluke kuye ngesistimu uhlobo mouthparts. Ngakho, kungenzeka ukubona mandibles abasakwazi ahlukahlukene umsebenzi, ukuma ngisho ngosayizi.

Ngakho, Coleoptera, Hymenoptera futhi Orthoptera mandibles esikhulu kakhulu. Phela, nabo basuke ayadingeka ukuze akuqede, izinyembezi bese ubamba ukudla.

Ngo impukane, isibonelo, uhlobo ikhotha mouthparts. Ngakho-ke mandibles bamane encishisiwe. A lezinyosi libhekene ikhotha-gnawing samuntu mouthparts. Ngakho, mandibles yabo, nakuba zikhona, kodwa ziyancipha kakhulu, ngaphezu kwalokho, balahlekelwe eyenza.

Zhukov

I mandibles enkulu kusukela Coleoptera, ngakho ngesikhathi mandible njengesixhumo sezindluzele ibhungane - oluqhamileyo ukuthi eminye nokuningi branched. Thina ibhungane Umgawuli lezi emihlathini inamandla. Ngezindlela eziningi, ukuma kanye nokuthuthukiswa mandible kuncike hlobo okuphakelayo lunye bug ethile.

Ngezinye phansi mabhungane, isibonelo, ongenhla eside. Ngosizo lwabo, ungakwazi lula ukuthola ilungelo aphume igobolondo lomnenke.

Izinyosi, izintuthwane kanye iminyovu

Ukuze mandible Hymenoptera - ke zhvatelnye mandibles, efana uhlobo bakudala kubo. Basebenzisa ukuba:

• Killing inyamazane.
• Ukumba Burrows.
• ukusika izitshalo.

• Ukugcinwa ukudla kwayo.

Kulokhu, nemihlathi engezansi abe uhlobo Licking futhi iklanyelwe ukuqoqa umpe.

Ngo Diptera futhi Lepidoptera

Ngo Diptera mandibles kakhulu ukushintshwa. Yingakho kwezinye omiyane nezimpukane okuyinto ncela igazi, mandibles kukhona stilettos. Ngosizo lwabo, isinambuzane kuhlaba isikhumba. Kodwa mpukane evamile futhi ngokuphelele elahlekile emhlathini layo elingenhla. Ngemva mouthparts wakhe badinga kuphela ukudla okuwuketshezi.

Zonke izibungu Lepidoptera kukhona mandibles, ezithinta uhlobo gnawing. Nokho, leli bhu toothed kuphela emsebenzini wabo waze waba mdala. izimvemvane Abaningi mandibles ulahlekelwe. It ephenduka ibe lezi ezincane oncelayo ukuba ukwazi ukumunca umpe olumnandi.

Mandible - umhlathi kusukela izinambuzane, okuyinto zitholakala phezulu. Zonke lezi mandibles zihlukile, kuye ngokuthi lapho babelibangise khona.
