Abanikazi abaninzi beekati bathanda ukusondela kwiikati, kodwa iikati eziqhenkcezayo ziyala ukuchukumisa abantu abangenangqiqo yemida kwaye bafuna ukuchukumisa izandla zabo ngokukhawuleza xa beza.
Kutheni kunzima kangaka ukubamba izandla neekati?
Enyanisweni, ngokungafaniyo nezinja ezithembekileyo, abantu abazange bazifuye ngokupheleleyo iikati zasekhaya.
Njengeekati ezininzi, iikati zizalelwa ukuba zizingela zodwa.Uninzi lweekati ezifuywayo zisayigcinile indalo yazo yasendle, izakhono zazo zokuzingela kunye nokuxhwila zisebukhali, kwaye zinokuphila ngokulula ngaphandle kwabantu.
Ngoko ke, emehlweni eekati, azizange zifuywe nabani na.Njengerhamncwa elilodwa, kuyinto eqhelekileyo ukuba nekratshi nokungakhathali.
Ingakumbi into ofuna ukuyiphatha ziinzipho zabo eziethe-ethe.Kwiikati, ezi ziphoso zine zizinto zakudala eziye zavela kwiminyaka emininzi yokuhambahamba kwihlabathi, kwaye kunengqiqo ukuba ungakuvumeli ukuba uzichukumise.
Esi sibini se-paw pads siqulunqwe ngamanqwanqwa amathathu esakhiwo esichanekileyo, esinokwenza ukuba nezihlangu zemidlalo eziqeqeshiweyo zizive ziphantsi.
Owona mgangatho ungaphandle ngumaleko we-epidermal.Njengenxalenye edibana ngokuthe ngqo nomhlaba, lo maleko we-sole yenziwe ngeyona nto inzima.Inoxanduva lokumelana ngokuthe ngqo nokungqubuzana kunye nempembelelo ngexesha lokuzilolonga kwaye ineempawu ezichasene nokunxiba.
Umaleko wesibini, obizwa ngokuba yidermis, utyebile kwiintsinga ezilastiki kunye necollagen fibers kwaye unokumelana noxinzelelo olunamandla.I-dermal papilla, equlethwe ngamathambo e-matrix, idibene ne-epidermis ukwenza isakhiwo se-honeycomb esinceda ukufunxa impembelelo ngexesha leempembelelo.Lo maleko usembindini ufana nomqamelo womoya kwi sole kwaye unesiphumo esihle kakhulu sokufunxa ukothuka.
Uluhlu lwesithathu, olubizwa ngokuba yi-subcutaneous layer, luqulunqwe ngokuyintloko ngamathambo anamafutha kwaye ngowona maleko abalulekileyo afunxa amandla kwi-paw pad.Njengowona maleko ungaphakathi kunye nothambileyo phakathi kwemigangatho emithathu, ilingana nokongeza umaleko oshinyeneyo womqamelo kwizihlangu ezisicaba, okuvumela iikati ukuba zonwabele “ukunyathela indle”.
Kungenxa kanye le seti yeepaw pads ezinamandla ezinokuthi iikati zibhabhe phezu kweendonga kunye neendonga ngokulula, kwaye zinokutsiba ukuya kuma-4.5 ubude bomzimba ngokutsiba okunye.
I-metacarpal pad esembindini wepati yangaphambili yekati kunye neepadi ezimbini zeenzwane zangaphandle zithwala amandla amakhulu xa ihleli.Umsebenzi weenzipho zekati unokuba ngaphezulu kakhulu kunale.Ukongeza kumsebenzi wokufunxa ukothuka, okona kubaluleke kakhulu, ikati inokuzisebenzisa ukuva imeko engqongileyo.okusingqongileyo.
Iintlobo ngeentlobo zee-receptors zisasazwa ngokuxineneyo kwi-paw pads yeekati [5].Ezi zamkeli zinokusasaza izinto ezahlukeneyo ezikhuthazayo kwimo engqongileyo zisiya ebuchotsheni, zivumela iikati ukuba zibone ulwazi olwahlukeneyo oluzingqongileyo ngeezipho zazo zodwa.
Impendulo ye-Cutaneous sensory evela kwi-paw pads idlala indima ebalulekileyo ekulawuleni ukulingana komzimba, ngokukodwa kwiindawo ezingalinganiyo ezifana neeleli okanye amathambeka, apho ukulahlekelwa kwemvakalelo yesikhumba kuya kuchaphazela kakhulu ukulinganisa ukulinganisa.Kwimilinganiselo yokwenyani, xa i-receptors kwelinye icala le-paw pad ibanjwe ngamachiza, indawo yekati yomxhuzulane iya kutshintshela ngokungazi kwicala le-anesthetized ngelixa ihamba.
Ngaphakathi kwiziphopho zekati, kukwakho nesixhobo esibizwa ngokuba yiPacinian corpuscle, esinobuntununtunu xa kungcangcazela okungama-200-400Hz, nto leyo enika ikati ikwazi ukubona ukungcangcazela komhlaba ngeenzipho zayo.
Ezi zamkeli zifumana ulwazi olwahlukileyo kokusingqongileyo kwaye ziyasebenzisana ukuze zikhulise kakhulu amandla ekati okubona imeko engqongileyo.
Ngokukodwa malunga nokuqonda isantya kunye nendlela yokuhamba, iinzipho zinokwanda okucacileyo kweekati.Asikokubaxa ukuthi angamehlo angaphezulu eekati.Ngapha koko, ukuma kobuchopho bekati obusebenzisa ulwazi olubambekayo lweenzipho ikwindawo enye neliso elisebenza kwinkcazelo ebonwayo.
Ayisiyiyo loo nto kuphela, iinzipho zekati ziyakwazi ukubona ngokucacileyo umahluko kwiqondo lobushushu, kwaye uvakalelo lwazo kwiqondo lobushushu alukho mbi ngakumbi kunolo lweentende zomntu.Ziyakwazi ukubona umahluko wobushushu obuncinci njenge-1°C.Xa udibana namaqondo obushushu aphezulu, njengoko kuphela kwenxalenye yomzimba wekati exhotyiswe nge-eccrine sweat glands, iipaw pads zinokudlala indima ekukhupheni ubushushu.
Iikati zinokususa ubushushu obuthile ngokuphuma komphunga ngokufaka amathe ezinweleni zazo.
Ke ngoko, le seti yezinto zakudala ibaluleke kakhulu kubantu bekati.Iyakwazi ukubhabha phezu kweendonga kwaye inokubona onke amacala.Kwabo abangaqhelananga nabo, izandla zeekati eziziqhenyayo azikho into onokuyitsala ukuba ufuna.
Ukuze ukwazi i-kitten ngokukhawuleza, unako ukuvula iitoti ezininzi kunye nokwakha ubudlelwane obuhle kunye nekati.Mhlawumbi ngenye imini intshontsho lekati liya kukuvumela ukuba ucinezele iinzipho zalo ezixabisekileyo.
