Ntau tus tswv miv nyiam mus ze rau cov miv, tab sis cov miv zoo siab tsis kam kov tib neeg uas tsis muaj kev nkag siab ntawm ib thaj tsam thiab xav kov lawv txhais tes sai li sai tau thaum lawv tuaj txog.
Vim li cas nws thiaj li nyuaj rau tuav tes nrog miv?
Qhov tseeb, tsis zoo li cov dev ncaj ncees, tib neeg yeej tsis tau txais cov miv hauv tsev.
Zoo li ntau tus felines, miv yug los ua ib leeg neeg yos hav zoov.Feem ntau cov miv hauv tsev tseem khaws lawv qhov qub qub qub, lawv cov txuj ci yos hav zoov thiab khawb av tseem ntse, thiab lawv tuaj yeem yooj yim ciaj sia ntawm tib neeg.
Yog li ntawd, nyob rau hauv lub qhov muag ntawm miv, lawv yeej tsis muaj leej twg tus tsiaj.Raws li ib tug tib neeg predator, nws yog ib txwm ua dog dig arrogant thiab aloof.
Tshwj xeeb tshaj yog qhov koj xav kov yog lawv cov ilv claws.Rau miv, plaub claws no yog cov khoom qub uas tau hloov zuj zus mus ntau xyoo ntawm kev mus ncig thoob ntiaj teb, thiab nws tsim nyog tsis txhob cia koj kov lawv.
Ob lub paw pads no yog tsim los ntawm peb txheej ntawm precision qauv, uas yuav ua rau cov kev ua kis las khau zoo li tsis zoo.
Cov txheej txheej sab nraud yog txheej txheej epidermis.Raws li ib feem ntawm kev sib cuag ncaj qha nrog hauv av, cov txheej txheej no yog tsim los ntawm cov khoom siv tawv tshaj plaws.Nws yog lub luag haujlwm rau ncaj qha tiv thaiv kev sib txhuam thiab cuam tshuam thaum lub sijhawm ua haujlwm thiab muaj tag nrho cov khoom tiv thaiv hnav.
Qhov thib ob txheej, hu ua dermis, yog nplua nuj nyob rau hauv elastic fibers thiab collagen fibers thiab muaj peev xwm tiv taus siab zog.Lub dermal papilla, uas yog tsim los ntawm cov ntaub so ntswg matrix, yog intertwined nrog lub epidermis los tsim ib tug honeycomb qauv uas pab nqus cov kev cuam tshuam thaum muaj kev cuam tshuam.Cov txheej hauv nruab nrab no zoo li lub cushion cua hauv ib leeg thiab muaj qhov cuam tshuam zoo heev.
Qhov thib peb txheej, hu ua subcutaneous txheej, yog tsim los ntawm cov ntaub so ntswg fatty thiab yog lub tseem ceeb tshaj plaws zog-absorbing txheej nyob rau hauv lub paw ncoo.Raws li cov txheej sab hauv thiab softest ntawm peb cov khaubncaws sab nraud povtseg, nws yog sib npaug rau ntxiv txheej tuab ntawm lub cushion rau cov khau tiaj tus, tso cai rau miv kom txaus siab rau kev txaus siab ntawm "stepping on poop".
Nws yog qhov tseeb vim tias cov txheej txheem no muaj zog paw pads uas miv tuaj yeem ya hla cov phab ntsa thiab phab ntsa yooj yim, thiab tuaj yeem dhia mus txog 4.5 npaug ntawm lawv lub cev ntev hauv ib qho leap.
Lub metacarpal ncoo nyob rau hauv nruab nrab ntawm tus miv lub paw pem hauv ntej thiab ob sab ntiv taw ntiv taw dais lub ntsiab quab yuam thaum nws tsaws.Kev ua haujlwm ntawm miv lub claws tuaj yeem ua tau ntau dua li cov no.Ntxiv nrog rau kev ua haujlwm poob siab, qhov tseem ceeb tshaj, tus miv tuaj yeem siv lawv kom nkag siab qhov chaw ib puag ncig.ib puag ncig.
Miv 'paw pads yog densely faib nrog ntau yam receptors [5].Cov receptors no tuaj yeem xa tawm ntau yam stimuli hauv ib puag ncig rau lub hlwb, tso cai rau miv kom pom ntau yam ntaub ntawv nyob ib puag ncig lawv nrog lawv cov claws.
Cov lus pom ntawm daim tawv nqaij los ntawm paw pads plays lub luag haujlwm tseem ceeb hauv kev tswj hwm lub cev sib npaug, tshwj xeeb tshaj yog nyob rau ntawm qhov chaw tsis sib xws xws li ntaiv lossis qhov chaw siab, qhov uas qhov poob ntawm daim tawv nqaij yuav cuam tshuam rau kev sib npaug.Hauv kev ntsuas tiag tiag, thaum cov receptors ntawm ib sab ntawm lub paw ncoo yog loog los ntawm cov tshuaj, tus miv qhov chaw ntawm lub ntiajteb txawj nqus yuav tsis nco qab hloov mus rau sab anesthetized thaum taug kev.
Nyob rau hauv cov miv lub claws, kuj muaj ib tug receptor hu ua Pacinian corpuscle, uas yog rhiab heev rau vibrations ntawm 200-400Hz, muab tus miv lub peev xwm mus ntes av vibrations nrog nws claws.
Cov receptors no tau txais ntau yam ntaub ntawv los ntawm ib puag ncig thiab koom tes nrog ib leeg los txhim kho tus miv lub peev xwm kom pom qhov chaw ib puag ncig.
Tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm kev hnov qhov ceev thiab kev taw qhia ntawm kev txav, cov claws muaj qhov pom tseeb tshaj plaws rau cov miv.Nws tsis yog ib qho exaggeration hais tias lawv yog miv qhov muag ntxiv.Tom qab tag nrho, txoj hauj lwm ntawm tus miv lub hlwb uas ua cov ntaub ntawv tactile ntawm cov claws yog nyob rau hauv tib cheeb tsam li lub qhov muag uas ua cov ntaub ntawv pom.
Tsis tas li ntawd xwb, miv claws kuj tseem tuaj yeem kuaj pom qhov sib txawv ntawm qhov kub thiab txias, thiab lawv qhov rhiab heev rau qhov kub thiab txias tsis yog phem dua li ntawm tib neeg lub xib teg.Lawv tuaj yeem pom qhov sib txawv ntawm qhov kub thiab txias li 1 ° C.Thaum ntsib qhov kub thiab txias, tsuas yog ib feem ntawm tus miv lub cev nruab nrog cov qog hws eccrine, cov paw pads tuaj yeem ua lub luag haujlwm hauv cov cua sov.
Miv kuj tuaj yeem tshem tawm qee qhov cua sov los ntawm evaporation los ntawm kev siv qaub ncaug rau lawv cov plaub hau.
Yog li ntawd, cov txheej txheem artifacts no tseem ceeb heev rau cov neeg miv.Nws tuaj yeem ya hla phab ntsa thiab tuaj yeem pom txhua qhov kev taw qhia.Rau cov neeg uas tsis paub nrog lawv, txhais tes ntawm cov miv zoo siab tsis yog ib yam uas koj tuaj yeem rub tau yog tias koj xav tau.
Txhawm rau kom paub tus menyuam miv sai li sai tau, koj tuaj yeem qhib ntau lub kaus poom thiab tsim kev sib raug zoo nrog tus miv.Tej zaum muaj ib hnub tus menyuam miv yuav tso cai rau koj hle lawv cov claws muaj nuj nqis.
