Mbali za masomphenya amphaka ndi momwe amawonera dziko lozungulira iwo

Anthu amachita chidwi ndi kukongola ndi chinsinsi cha maso amphaka, koma zimakhala bwanji kuyang'ana dziko ndi maso a chiweto? Kodi amphaka amawona bwanji dziko lathu?

Akatswiri a Hill amakamba za mtundu wa amphaka a maso, kaya amawona usiku komanso ngati amasiyanitsa mitundu. Chilichonse chomwe muyenera kudziwa zokhudza masomphenya a pet!

Masomphenya amphaka: momwe amawonera

Eni amphaka nthawi zina amamva kuti anzawo aubweya akuwona zomwe sali. Nthawi zambiri zimakhala. Amphaka sangakhale ndi mphamvu yachisanu ndi chimodzi, koma amakhala ndi chikope chachitatu, nembanemba yopyapyala yomwe imapereka chitetezo chowonjezera. Komanso, maso awo amakula kwambiri.

Kodi amphaka amawona bwanji usiku?

Ngakhale mphekesera, amphaka alibe masomphenya usiku. Koma malinga ndi kunena kwa Merck Veterinary Manual, “amphaka amawona bwino kuwirikiza kasanu ndi kamodzi m’kuunika kocheperako kuposa anthu.” Ichi ndi chifukwa cha chipangizo cha masomphenya nyama zimenezi. Photoreceptors awo amapangidwa ndi ndodo ndi cones. Amakhala ndi ndodo zambiri, ndipo amatha kumva kuwala kuposa ma cones. Chifukwa chake, kuchuluka kwa ndodo zotere kumawapangitsa kuti athe kuzindikira mawonekedwe ochulukirapo ndikuyenda pang'onopang'ono. Masomphenya a amphaka mumdima sali angwiro, koma mumdima wamdima ndi wabwino kwambiri kuposa anthu!

Chifukwa china chimene amphaka amawona bwino mumdima ndi chomwe chimatchedwa galasi wosanjikiza kuseri kwa retina, chomwe chimawonetsera kuwala komwe kumatengedwa ndi diso. Ngati ndodo yomwe ili mu diso la munthu “sikuwona” kuwala, monga momwe ABC Science Australia ikulongosolera, imatengedwa ndi diso lakuda lomwe lili kuseri kwa diso. Komabe, amphaka, “ngati kuwala sikugunda ndodo, kumawonekera kuchokera pamwamba pake. Pambuyo pake, kuwalako kumapeza mwayi wachiwiri kugunda ndodo ndikugwira ntchito,” akufotokoza ABC.

Chifukwa cha maso amatsenga agalasi awa, amphaka amatha kuwona zinthu zoyenda m'chipinda zomwe anthu sangaziwone. (Nthawi zambiri amasanduka fumbi chabe, osati zinthu zachilendo.) Zonsezi ndi zinsinsi za mmene amphaka amaonera mumdima.

Kodi amphaka amawona mitundu?

Lingaliro lakuti amphaka ali ndi masomphenya akuda ndi oyera ndi nthano chabe, akutero AdelaideVet. Koma bwenzi laubweya silitha kuzindikira mitundu yonse yamitundu yomwe munthu amatha kuwona. Kumbali imodzi, mwaukadaulo, amphaka sakhala ndi khungu chifukwa sangathe kusiyanitsa mitundu yonse. Kumbali ina, amatha kuona mitundu ina, ngakhale yosamveka.

Maonekedwe a diso lake salola mphaka kuona mitundu yonse ya utawaleza. Anthu ali ndi ma photopigment receptors atatu, pamene amphaka ali ndi awiri okha, zomwe zimalepheretsa maonekedwe awo. Mitundu yomwe imawoneka yodzaza kwambiri kwa ife imawoneka ngati pastel kwa amphaka. Apanso, iyi ndi ntchito ya cones. Ziweto zimawona dziko lapansi bwino mumithunzi ya imvi, komanso zimachita bwino ndi buluu ndi chikasu. Koma mofanana ndi anthu amene amaonedwa kuti ndi akhungu, amavutika kusiyanitsa zobiriwira ndi zofiira. Makamaka, mtundu wofiira umadziwika ndi iwo ngati chinthu chakuda.

Maonekedwe a masomphenya amphaka: pali masomphenya a chilombo

Amphaka ndi ochenjera komanso osakasaka bwino, ndipo chifukwa cha izi ayenera kuthokoza maso awo amphongo. Kuwoneka bwino kumawathandiza kuti azitha kuwona ngakhale kusuntha kwakung'ono kapena zolemba zobisika za nyama. Amphaka, monga anthu, ali ndi masomphenya ochepa ozungulira, koma amawapanga ndi kuthwa kwake, komanso malo a maso. Popeza maso awo amatembenuzidwira kutsogolo, monga a anthu, amphaka amatha kudziwa molondola mtunda pakati pawo ndi nyama zawo, kutsimikizira kulondola kwawo ndi kupambana kwawo pogonjetsa mdani.

Masomphenya kapena kumva: chomwe chili chofunika kwambiri kwa mphaka

Ngakhale zonse zodabwitsa zimatha masomphenya a mphaka, chidziwitso chodziwika bwino cha mphaka sikuwona, koma kumva.

Kumva kwake n’kovuta kwambiri moti, malinga ndi kunena kwa Animal Planet, “mphaka amene ali pamtunda wa mamita angapo kuchokera pamene pali phokoso angaloze kumene ali mkati mwa masentimita ochepa chabe m’magawo mazana asanu ndi limodzi a sekondi imodzi.” Amphaka amatha kumva phokoso patali kwambiri… ndipo amazindikira kusiyana kwakung'ono kwambiri kwa mawu, kutsata kusiyana pang'ono ngati gawo limodzi mwa magawo khumi a kamvekedwe, zomwe zimawathandiza kudziwa mtundu ndi kukula kwa nyama yomwe ikupanga phokoso."

Pali nthano zambiri ndi malingaliro olakwika okhudza amphaka. Ndipo ngakhale kuti akatswiri a sayansi ya zamoyo amatha kufotokoza zodabwitsa zosiyanasiyana m’njira imene amphaka amaonera, amakhalabe ndi makhalidwe ambiri. Izi zimawapangitsa kukhala zolengedwa zosamvetsetseka zomwe anthu amakondadi. Ndipo kupatsidwa acuteness kumva ndi masomphenya amphaka, n'zosadabwitsa kuti amalamulira dziko.
