Mandible - izinambuzane umhlathi?

a - Mandible maxilla arthropods. Oku iqulathe mouthparts ye ngeembadada izinto ezifanayo. Uninzi izinambuzane, kwakunye amasongololo ezineqokobhe mandible ikhona ukugaya ukutya. Noko ke, izinambuzane zentlalo, kukho enye inkalo lwesi sakhi - iindlwane.

imvelaphi

Mandible - yinto efanayo njengoko mandibles. Kuyinto i ziqwempu intloko esiphelweni ukuba ngexesha nasekusungulweni modified kakhulu. Kukho ingcamango yokuba uguqulwe koksopodity kunye endite. Xa ke bebexhotyiswa kwezilwanyana yamandulo.

Mandibles ezi ziqwempu eqinileyo camera le sclera, ngomhla apho iibhrashi kunye tivekiki ezahlukeneyo. Kubonakala ukuba emva iindevu.

Zonke abameli babe entognatha ziyavela isakhiwo mandible. Bona apha kuphela kwenye indawo ukuya entloko. Boca ngomlomo wabo ngokuthembekileyo tho umlebe ephantsi (a inxalenye icala kuyo). Ngako oko, kucebisa akhiwa. Kulo baza babeka emhlathini; bobabini ezisezantsi neziphezulu. Kungenxa yale msebenzi, iklasi yonke wabizwa ngokuba "entognatha".

Xa inyakanyaka enamaphiko, kunye schetinohvostok, ngaphandle kweli cala kwindawo zokucacisa, kukho esinye ngaphezulu. Ngenxa kule banalo ithuba lokwenza mandibles abalimi intshukumo enamandla ivale.

Zonke izinambuzane kufuneka mandibles, ukusuka kwiindawo zazo ukuhambisana kunye imicu intloko suka. Kuyimfuneko ukuba kuthinjwe izihlunu elawula ezi mandibles.

features ezisebenzayo

izinambuzane Mandible usenokwahluka ngokuxhomekeke kuhlobo mouthparts. Ngako oko, sinako ukubona mandibles abasakwazi ezahlukeneyo kumsebenzi, ziphembelele kunye nobukhulu.

Ngoko ke, Coleoptera, Hymenoptera kunye Orthoptera mandibles ezinkulu kakhulu. Ngapha koko, ukuba kuyimfuneko ukwenzela ukuba awadubadube, iinyembezi ucinezele ukutya.

Kule fly, umzekelo, uhlobo wayimunca mouthparts. Ngenxa yoko mandibles nje lincitshiswe. A iinyosi luphawulwa wayimunca-eyiva mouthparts lwalo. Ngako oko, mandibles zabo, nangona kukho, kodwa kunciphise kakhulu, ngaphezu koko, baye balahlekelwa jaggedness.

zhukov

Le mandibles inkulu ukusuka Coleoptera, njalo kwi nexhama beetle mandible - ibinophondo olubonakalayo ukuba ngakumbi nangakumbi branched. We bhungane mgawuli le imihlathi namandla. Ngeendlela ezininzi, imilo kunye nophuhliso mandible kuxhomekeke kuhlobo feed ekuthatheni izifundo njengeziphambili a bug ethile.

Maxa amabhungane emhlabeni, umzekelo, kwemihlathi yangasentla elide. Ngoncedo lwabo, unako lula ukuba ekunene ngaphandle iqokobhe lenkumba.

Iinyosi, iimbovane kunye noonomeva

Kuba mandible Hymenoptera - it zhvatelnye mandibles, zazo uhlobo ukuzazi kwabo. Basebenzisa ukuba:

• Ukubulala ixhoba.
• Ukumba imingxuma.
• ahlabayo izityalo.
• Yenza ngonyawo.
• Nokugcinwa ukudla kwayo.

Kulo mzekelo, nemihlathi ephantsi ibenodidi isikhotha nesilungiselelwe ukuba incindi.

In Diptera and lepidoptera

In Diptera mandibles elungisiweyo kakhulu. Ngenxa yoko, kwezinye iingcongconi neempukane leyo wanyisa igazi, mandibles ezi stilettos. Ngoncedo lwabo, esi sinambuzane lihlaba isikhumba. Kodwa mpukane nangokupheleleyo ezilahlekileyo kumhlathi aphezulu. mouthparts zakhe kufuneka kuphela emva kokuba ukutya ukutya ulwelo.

Zonke Imibungu of lepidoptera na mandibles, banayo uhlobo eyiva. Noko ke, kuphela nanundu unamazinyo emsebenzini wabo omdala. Abaninzi amabhabhathane mandibles balahlekelwe. Nokuba litshatshazi, laba nkawu ezincinane owanyayo lokufunxa umpe.

Mandible - nomhlathi evela izinambuzane, apho ibekwe ngaphezulu. Zonke ezi mandibles zahlukile, ngokuxhomekeke kuyo lwabo.
