Amphaka ambiri amakonda kuyandikira pafupi ndi amphaka, koma amphaka onyada amakana kukhudza anthu omwe alibe malire ndipo amafuna kukhudza manja awo atangotuluka.
N'chifukwa chiyani kugwirana chanza ndi amphaka kumakhala kovuta?
Ndipotu, mosiyana ndi agalu okhulupirika, anthu sanawete amphaka kotheratu.
Mofanana ndi amphaka ambiri, amphaka amabadwa kuti azisaka okha.Amphaka ambiri akutchire amakhalabe ndi chikhalidwe chawo choyambirira, luso lawo losaka ndi kupha nyama akadali lakuthwa, ndipo amatha kukhala ndi moyo mosavuta popanda anthu.
Choncho, pamaso pa amphaka, iwo sali ziweto za aliyense.Monga nyama yolusa yokhayokha, n’kwachibadwa kukhala wodzikuza ndi wosadzikonda.
Makamaka zomwe mukufuna kukhudza ndi zikhadabo zawo zosalimba.Kwa amphaka, zikhadabo zinayizi ndi zinthu zakale zomwe zakhala zikuchitika kwa zaka zambiri zoyendayenda padziko lonse lapansi, ndipo ndi zomveka kuti musamakhudze.
Ma paw pads awa amapangidwa ndi zigawo zitatu zolongosoka, zomwe zingapangitse ngakhale nsapato zamasewera odziwika kuti ndi otsika.
Mbali yakunja ndi epidermal layer.Monga gawo lomwe limalumikizana mwachindunji ndi nthaka, wosanjikiza wokhawo umapangidwa ndi zinthu zolimba kwambiri.Imakhala ndi udindo wothana ndi mikangano komanso mphamvu panthawi yochita masewera olimbitsa thupi ndipo imakhala ndi anti-wear properties.
Chigawo chachiwiri, chotchedwa dermis, chimakhala ndi ulusi wotanuka komanso ulusi wa kolajeni ndipo chimatha kupirira kupanikizika kwambiri.The dermal papilla, yomwe imapangidwa ndi minofu ya matrix, imalumikizana ndi epidermis kuti ipange chisa cha uchi chomwe chimathandiza kuyamwa mphamvu pakukhudzidwa.Wosanjikiza wapakati uwu ali ngati khushoni la mpweya pachokhacho ndipo ali ndi mphamvu yabwino kwambiri yoyamwitsa.
Chigawo chachitatu, chotchedwa subcutaneous layer, chimapangidwa makamaka ndi minofu yamafuta ndipo ndi gawo lofunika kwambiri lotengera mphamvu mu paw pad.Monga wosanjikiza wamkati ndi wofewa kwambiri pakati pa zigawo zitatuzi, ndizofanana ndi kuwonjezera mzere wochuluka wa khushoni ku nsapato zophwanyika, zomwe zimalola amphaka kusangalala ndi "kuponda pa poop".
Ndi chifukwa cha zida zamphamvuzi zomwe amphaka amatha kuwuluka makoma ndi makoma mosavuta, ndipo amatha kulumpha mpaka 4.5 kutalika kwa thupi lawo pakudumpha kumodzi.
Mphepete mwa metacarpal yomwe ili pakati pa phazi lakutsogolo la mphaka ndi zala ziwiri zakunja zapamapazi zimakhala ndi mphamvu yaikulu ikatera.Ntchito za zikhadabo za mphaka zimatha kukhala zambiri kuposa izi.Kuphatikiza pa ntchito yodzidzimutsa, chofunika kwambiri, mphaka amatha kuzigwiritsa ntchito kuti azindikire malo ozungulira.chilengedwe.
Mitundu yosiyanasiyana ya ma receptor imagawidwa kwambiri pamapadi amphaka [5].Ma receptor awa amatha kufalitsa zinthu zosiyanasiyana zachilengedwe kupita ku ubongo, zomwe zimalola amphaka kuzindikira zambiri zowazungulira ndi zikhadabo zawo zokha.
Ndemanga zapakhungu zochokera ku paw pads zimagwira ntchito yofunika kwambiri pakuwongolera thupi, makamaka pamalo osagwirizana monga makwerero kapena malo otsetsereka, pomwe kutayika kwa khungu kumakhudza kwambiri kuwongolera bwino.M'miyeso yeniyeni, pamene zolandilira mbali imodzi ya paw pad zaziziritsidwa ndi mankhwala, mphamvu yokoka ya mphaka imasuntha mosazindikira kupita ku mbali yogonetsa pamene akuyenda.
Mkati mwa zikhadabo za mphaka, mulinso cholandilira chotchedwa Pacinian corpuscle, chomwe chimamva kunjenjemera kwa 200-400Hz, zomwe zimapatsa mphaka mphamvu yozindikira kugwedezeka kwa nthaka ndi zikhadabo zake.
Ma receptor awa amalandira zidziwitso zosiyanasiyana kuchokera ku chilengedwe ndikuthandizana wina ndi mnzake kuti apititse patsogolo luso la mphaka lozindikira malo ozungulira.
Makamaka pozindikira kuthamanga ndi kayendetsedwe ka kayendetsedwe kake, zikhadabo zimakhala ndi kuwonjezeka kwakukulu kwa amphaka.Sikokokomeza kunena kuti ndi maso owonjezera amphaka.Ndi iko komwe, malo a ubongo wa mphaka umene umagwiritsa ntchito chidziwitso chokhudza zikhadabo uli pamalo omwewo ndi diso lomwe limagwiritsa ntchito zinthu zowoneka.
Sizokhazo, zikhadabo za mphaka zimathanso kuzindikira bwino kusiyana kwa kutentha, ndipo kukhudzidwa kwawo ndi kutentha sikuli koipa kuposa kwa kanjedza.Amatha kuzindikira kusiyana kwa kutentha kochepera 1 ° C.Mukakumana ndi kutentha kwakukulu, popeza gawo lokhalo la mphaka lomwe lili ndi ma eccrine sweat glands, paw pads amathanso kuchitapo kanthu pochotsa kutentha.
Amphaka amathanso kuchotsa kutentha kwina kudzera mu nthunzi popaka malovu kutsitsi lawo.
Chifukwa chake, zinthu zakalezi ndizofunika kwambiri kwa amphaka.Imatha kuuluka pamwamba pa makoma ndipo imatha kuona mbali zonse.Kwa iwo omwe sakuwadziwa bwino, manja a amphaka onyada sali chinthu chomwe mungathe kukoka ngati mukufuna.
Kuti mudziwe kalulu mwamsanga, mukhoza kutsegula zitini zambiri ndikupanga ubale wabwino ndi mphaka.Mwina tsiku lina mphaka adzakulolani kutsina zikhadabo zake zamtengo wapatali.
