Umbono weCanine ngumxholo onomdla kwaye uhlala ungaqondwa kakuhle. Ngaba wakha wazibuza ukuba izinja zibona njani ihlabathi elizingqongileyo? Esi sikhokelo sibanzi sijonge ukutyhila imfihlelo yombono we-canine. Ngokungafaniyo nabantu, izinja zineempawu ezizodwa kwimbono yazo ebonakalayo echaphazela indlela ezitolika ngayo indawo yazo. Ukuqonda lo mahluko kunokukunceda unxibelelane ngcono nesilwanyana sakho sasekhaya kwaye uphucule umgangatho wobomi baso.
I-Anatomy yeliso leNja
Umbono wezinja uqala ngeliso labo, i-anatomy yabo ifana kakhulu neyabantu, kodwa ngokwahlukana okuphawulekayo. Izinja zine a retina equlethe iindidi ezimbini zeeseli ze-photoreceptor: iicones kunye neentonga. Ngelixa i-retina yomntu ine-cones ephezulu ye-cones, ejongene nombono wombala kunye ne-visual acuity, i-retina yezinja ineentonga ezininzi, ezingcono ekuboneni kwiimeko zokukhanya okuphantsi.
Los Iinqanawa Bavumela izinja ukuba zibone ngcono ebumnyameni kodwa zincama ukubona umbala kunye nokubukhali okubonakalayo. Ukongeza, izinja zinesakhiwo esibizwa ngokuba itapetum lucidum, umaleko okhanyayo emva kweretina ophucula ukubona ebusuku ngokubuyisela ukukhanya kwiifotoreceptors.
Imibala Izinja Bona
Ngokuchasene neenkolelo ezithandwayo, izinja aziboni kumnyama namhlophe. Ngokwenene banombono we-dichromatic. Oku kuthetha ukuba banokubona kuphela imibala emibini esisiseko. Ngelixa abantu beneentlobo ezintathu zeecones (ezibomvu, eziluhlaza kunye nebhlowu), izinja zinezimbini kuphela (ezityheli nezibhlowu). Oku kukhokelela kumbala olinganiselweyo wephalethi kufana nombono obomvu-blue womntu onobumfama bombala.
Kwinja, imibala ebomvu neluhlaza inokuvela ngakumbi njengemithunzi engwevu okanye emdaka. Nangona kunjalo, oku akuchaphazeli kakhulu imisebenzi yabo yemihla ngemihla, kwaye izinja zihlawulela lo mda kunye nemvakalelo ebukhali yokuvumba kunye nezinye izakhono zokuziva.
Intsimi yoMbono kunye neMotion Perception
Olunye uphawu olunomdla lombono we-canine lulo Indawo ebanzi yokujonga. Amehlo ezinja abekwe ecaleni kwentloko yazo xa kuthelekiswa nabantu, ebanika indawo yombono weperipheral ephantse ibe ngama-240 degrees, xa kuthelekiswa ne-190 degrees ebantwini.
Ukongezelela, izinja zivakalelwa kakhulu kwintshukumo. Bayakwazi ukubona iintshukumo ezikhawulezayo nezikude ngcono kakhulu kunabantu, nto leyo eluncedo ekuzingeleni nasekugadweni. Ukukwazi kwabo ukuthatha iintshukumo ezincinci, ezikude ngomnye weempawu ezibenza babe ngabazingeli abagqwesileyo kunye nabagadi.
Umbono Wasebusuku Wezinja
Ndiyabulela itapetum lucidum kunye nokuxinana okuphezulu kweentonga kwi-retinas yazo, izinja zine umbono wasebusuku ungcono kakhulu kunowabantu. Bayakwazi ukubona kwiimeko eziphantsi kakhulu zokukhanya kwaye babone intshukumo ebumnyameni, izakhono eziyimfuneko kwizinyanya zezinja ezazizingela ngorhatya kunye nokusa.
I-tapetum lucidum ibonakalisa ukukhanya okungena esweni, inika ithuba elikhulu lokuba ii-photoreceptors zibambe ukukhanya okukhoyo. Oku kuphucula kakhulu imbono ebumnyameni, nangona ngexabiso lombono we-blurrier.
Curiosities malunga Dog Vision
Kukho imiba emininzi enomdla malunga umbono wenja oko kunokukothusa:
- Izinja zivame ukugxila bhetele kwizinto ezihambayo kunezinto ezimileyo.
- Phezu kwako nje ukungaboni kakuhle kwemibala, imibala ethile efana noluhlaza okwesibhakabhaka notyheli kulula kubo ukuyahlula.
- Izinja zinombono wobunzulu obungachanekanga kakhulu xa kuthelekiswa nabantu, ezinokuthi zihlawule ngokuhambisa intloko kunye nokutshintsha imbono yazo.
- Okokugqibela, izinja zibona kufutshane xa kuthelekiswa nabantu; Into esiyibona ngokucacileyo kwiimitha ezingama-20, bayibona ngcono malunga neemitha ezi-6.
Indlela Yokulungisa Imeko Yenja Yakho Ngokusekwe kumbono Wakhe
Ukuqonda indlela izinja ezibona ngayo kunokukunceda uphucule umgangatho wobomi bazo. Nanga amanye amacebiso:
- Sebenzisa amathoyizi ngemibala anokuyahlula ngokulula, njengeblues kunye nomthubi.
- Gcina ukhumbule ukuba izinja zithembele ngakumbi kwingqiqo yazo yokuvumba kunye nokuva kwiimeko eziphantsi, ngoko qiniseka ukuba indawo yazo yokudlala ikhanya kakuhle ukuba uyayifuna.
- Kulumkele utshintsho olukhawulezileyo kwindawo abahlala kuyo olunokubaphazamisa, ngakumbi ukuba sele bekhulile okanye banengxaki yokubona.
- Sebenzisa izibane zasebusuku kwiindawo apho inja yakho ihlala rhoqo ukwenzela ukuba kube lula ukuba ihambe xa kumnyama.
Umbono we-Canine lihlabathi elinomdla kwaye liyinkimbinkimbi elihluke kakhulu kumbono womntu. Ngokuyiqonda ngcono indlela abayibona ngayo indawo abahlala kuyo, sinokubanika ukhathalelo olungcono kunye nomgangatho wobomi opheleleyo.
