Umgca lateral lentlanzi kunye nendima yayo nokuziphatha nobomi neentlanzi

Iimvakalelo badlala indima ebaluleke gqitha kubomi nokuziphatha yeentlanzi. Fish, njengezinye ezinomqolo, abe iseti epheleleyo eyenziwa izivamvo ezintlanu. Kodwa ke ukuba kukho umahluko obalulekileyo - umgca osecaleni. Intlanzi le ilungu oluvo ekuthiwa wesithandathu. izilwanyana Land ngethuba zazivelela baye baphelelwa oko ngengqiqo yesithandathu, kodwa wahlala zasemanzini kunye kunokuba lula ubomi babo, inceda kusinda baze badle.

Anatomy of intlanzi. ingqondo

Enye yezinto eziphambili izitho kwiintlanzi zithathwa ingqiqo ivumba kunye nemvakalo. Ngoncedo lwabo, bakwazi ukukhetha up nokuba utshintsho ezincinane bume. Fish Pike, umzekelo, ngokusebenzisa umlomo kuphela sondleke, kodwa uziva kokuchukunyiswa emhlabeni, oku kuphendula ngoko nangoko, ukutshintsha ulwalathiso. iiseli ezibuthathaka emlonyeni, ukudlulisa iminqweno-luvo, ebonisa ingozi kukuvela miqobo okanye ukutya.

Intlanzi kakhulu luyacolwa kuphuhliswa ingqondo lobushushu. Le uvakalelo oluphezulu ukuya ukuhla kwamaqondo obushushu kunye nabaphambukeli xi ku izilwanyana elizweni.

amalungu ukuqgiba zeentlanzi zifumaneka emacaleni intloko efana cone ezincinane. Ngoncedo lwabo, ukuba ukubona utshintsho nobume bamanzi. kakhulu ingakumbi ingqondo ivumba izilwanyana ukuba lokuzingela zasebusuku. Umzekelo, iintlanzi Pike nga ivumba lamaxhoba ndiyihlanganise ndiyidadise nje iimitha ezimbalwa.

line lateral. indawo

Izazinzulu abaninzi bakholelwa ukuba umgca osecaleni wentlanzi - ingqiqo ubalulekileyo umbutho, inceda izilwanyana uphile kamnandi. line lateral - uhlobo owawunenjongo enye, nto leyo izisa ndawonye zonke iiseli ezibuthathaka emzimbeni, ibekwe intloko okanye emzimbeni.

Igunya ibekwe wonke umzimba, iqala kwi intloko egqibela ngumsila wena. Anatomy of ntlanzi, iintlobo zazo kunye zenyathi amisele indawo umgca osecaleni kunye nombala wayo. Uhlobo enye, unokukhangela njenge umgca emhlophe eqaqambileyo, ngoxa abanye - a mnyama, umvumbo phantse abamnyama.

Inani elikhulu umgca osecaleni intlanzi inikwa ikopi enye. Kodwa kukho ezinye iintlobo ezinokuthi ndoqhayisa ezintlanu okanye ngaphezulu. Umgca lateral lentlanzi kunokuba obonakalayo kakhulu abangaboniyo, kwaye efihliweyo ezikalini yaye ngoko nangoko ephawuleka emehlweni oluntu. Kwezinye intlanzi yena arc ezimilise, abanye - ngokohlobo imivumbo ezixhuzuxhuzulayo encinane entloko.

Kukho iintlanzi, leyo akanayo ngengqiqo yesithandathu. Ezi ziquka mullet, Dallam, ezinye cyprinodontiformes usapho iintlanzi.

Umgca lateral ibandakanya ...

Njengokuba besesitshilo, umgca osecaleni wentlanzi luhlobo iziko ingqondo nemithambo ukuba iliso eyenzekayo emhlabeni. Yintoni na le ziko?

line lateral imele ingqokelela eziliqela receptors ezithi zibekwe phakathi kwabo ngexesha lokuphumla ethile. Ii-inokuba imiphantsi umbala okanye misinga leyo zilahlwa emacaleni umzimba. Uninzi ezenza zifihlwe phantsi kwesikhumba nakwiintlanzi. Kuphela nje ezimbalwa ukuza kumphezulu nefihlakeleyo ezikalini. Ziyafana pores evulekileyo apha esikhumbeni.

Ngaphakathi ijelo umgca osecaleni uzele ulwelo. ezenza Nerve (iinwele zabo sensory) Ukufakwa utshintsha isiginali kule ulwelo ngokwayo. Naluphi perturbation, utshintsho koxinzelelo okanye ubushushu bamanzi ungabangela receptors ngoko, amanzi ijelo ihamba. Utshintsho unamandla kwi yokuhlala iintlanzi, kokukhona uya kukhatywa lunwele-receptor, ulwazi ngokukhawuleza ungena kwinkqubo luvo.

Ixabiso umgca osecaleni kwiintlanzi

sixth sense, okanye umgca osecaleni kuvumela intlanzi ukuva indlela ezinye izilwanyana ezihlala emanzini, msinyane kunokuba ziya kwaziswa malunga namacandelo phambi okanye ivumba. Umgca lateral uyakwazi ukufaka utshintsho incinane uxinzelelo lwamanzi. Izazinzulu zithi ukuba umgama apho unako ukumisela ngozi izayo izihlandlo ezintandathu ubukhulu (ubude) nakwiintlanzi.

Ixabiso umgca osecaleni kwiintlanzi abangaboniyo esikhulu ngakumbi. Kukho izilwanyana bayakwazi ukuphendula kuphela ithunzi okanye ukukhanya, oko unaware ngokupheleleyo intshukumo emanzini. umgca osecaleni kulo mzekelo, ukuze kubuyekezelwe yokungaphuhliseki okanye ukungabikho ubuchule bokubonwayo okanye ukuqgiba.

Ukususela sideline rhoqo kuxhomekeke ubomi intlanzi. Ukuba yonakele, ezo ezenzeka ngaphandle ayejongwa izilwanyana ayikho ayakhanya. Iza kuyeka ukuba uyiphendule ingozi evela ngaphandle, akayi kuba nako ngokupheleleyo kuzingela ukunika ukutya, ezimela neentshaba. Kwaye kamsinya.

umgca osecaleni imvubu

Mhlawumbi bonke abalobi abanamava bayazi ixabiso umgca osecaleni nakwiintlanzi. Ngayo, intlanzi uyakwazi mgibe ingxolo lincinane kunye intlokoma yamanzi. Njengoko iingcali zithi, wadubula, uqhushumbo, incoko eqhelekileyo ngezwi bayavuswa, ifuthe kumgca kwicala amanzi ngoko nangoko "ivumba." ngoko A intlanzi usabela, esoyika baleka. Kungenxa yesi sizathu ukuba abalobi uzame ukuba ungaze ukwenza ingxolo phezu ichibi, ukuba ukuthetha phezulu kakhulu, kungekhona ukuze ulahle into emanzini.

Movement, ingxolo encinane kunye intlokoma kufuneka Ayinakwenza ngumlobi kunye masela emanzini. Abalobi abanamava bathi asenokukuloba kufuneka ume emanzini, kufuneka ngokuyimfuneko ukuhamba, jinga ulwelo. Kuphela kule meko ntlanzi line yayo osisi ivumba ukutya ndisishenxise kwicala le hook.
