Mandible - ndi nsagwada tizilombo?

Mandible - ndi maxilla arthropods. Tichipeza wa mouthparts wa peyala ya zinthu zofanana. Ambiri a tizilombo, komanso millipedes ndiponso nkhanu mandible kutichitikira akupera chakudya. Komabe, tizilombo chikhalidwe, pali mbali ina ya chinthu ichi - akumanga zisa.

magwero

Mandible - izo ziri chimodzimodzi monga mandibles lapansi. Ndi malekezero mutu zigawo kuti pa zamoyo wa kwambiri kusinthidwa. Pali kopanda kuti asandulike koksopodity ndi endite. Kamodzi ndi iwo anali okonzeka ndi nkhanu wakale.

Mandibles olimba zigawo lokutidwa wa sclera, pa zimene maburashi ndi tine zosiyanasiyana. Zikuoneka kuti ali kumbuyo mlomo chapamwamba.

nthumwi zonse ndi entognatha zimaonetseratu dongosolo mandible. Iwo amagwira yekha pa nthawi ina kumutu. Boca m'kamwa awo molondola zinaphatikizidwa kuti mlomo wa mmunsi (a mbali gawo la izo). Choncho, m'matumba anapanga. Mu ndipo anaikidwa nsagwada: onse m'munsi ndi chapamwamba. Izo chifukwa cha mbali, ophunzira onse anali kutchedwa "entognatha".

Tizilombo mapiko ndi schetinohvostok, popanda mbali iyi ya mfundo articulation, pali wodziwanso kuposa. Chifukwa ichi iwo ndi mwayi kuchita zamphamvu ndi kutseka mandibles obereketsa kuyenda.

tizilombo onse amene mandibles, ku malo awo articulation ndi mutu achoka tendon. M'pofunika ubwenzi minofu omwe amalamulira mandibles izi.

mbali zinchito

tizilombo Mandible zingasiyane malingana ndi mtundu wa mouthparts. Choncho n'zotheka kuona mandibles ndi osiyanasiyana kwambiri ntchito, kuumba ndipo ngakhale kukula.

Choncho, Coleoptera, Hymenoptera ndi Orthoptera lalikulu kwambiri mandibles. Ndipotu, ndi kofunika kuti afafanize, kuichotsa ndi kugwira chakudya.

Mu ntchentche Mwachitsanzo, mtundu nyambititsa mouthparts. Choncho mandibles amangoika yafupika. njuchi A yodziwika ndi nyambititsa-gnawing mouthparts chimake. Choncho, mandibles awo, ngakhale pali, koma achepetsa Komanso, iwo anataya jaggedness.

Zhukov

The mandibles lalikulu kwa Coleoptera, kotero pa mandible mbawala kachilomboka - nyanga otchuka amene zina ndi zina nthambi. Ife Chikumbu wokwera izi nsagwada amphamvu kwambiri. Mu njira zambiri, mawonekedwe ndi chitukuko cha mandible zimatengera mtundu wa chakudya specialization mu cholakwika makamaka.

Pa kafadala nthaka, mwachitsanzo, chapamwamba nsagwada yaitali. Ndi thandizo lawo, mukhoza n'zosavuta kupeza kuchokera mu chipolopolo nkhono.

Njuchi, nyerere ndi mavu

Pakuti mandible Hymenoptera - izo zhvatelnye mandibles, amene amafanana wosazindikira mtundu iwo. Iwo ntchito:

• Kupha nyama.
• Kukumba kamakumba una.
• kudula zomera.
• Pangani bowo la.
• Posungira chakudya ake.

Pankhaniyi, nsagwada m'munsi ndi mtundu nyambititsa ndi cholinga kusonkhanitsa timadzi tokoma.

Mu Diptera ndi Lepidoptera

Mu Diptera mandibles kwambiri kusinthidwa. Choncho, ena udzudzu ndi ntchentche omwe akuyamwitsa magazi, mandibles ndi stilettos. Ndi thandizo lawo, tizilombo napyoza khungu. Koma ntchentche ndi linasiiratu nsagwada zake chapamwamba. Pambuyo mouthparts ake ochepa okha kudya chakudya madzi.

Onse mbozi wa Lepidoptera ndi mandibles, amene mtundu gnawing. Komatu imodzi njenjete kusunga iwo mukadzakula. Ambiri agulugufe mandibles kutaya. Likukhalira ku yaing'ono Zikuluzikulu woyamwa kuyamwa timadzi tokoma wokoma.

Mandible - ndi nsagwada tizilombo, zomwe zili pamwamba. mandibles zonsezi osiyana, malingana kopita kwawo.
