Qhov muag yooj yim thiab ob lub qhov muag yog ob lub qhov muag tseem ceeb hauv cov tsiaj, thiab muaj ntau qhov sib txawv ntawm ib leeg. Yuav kom nkag siab seb lub qhov muag tshwj xeeb yog qhov muag sib xyaw lossis lub qhov muag yooj yim, nws yuav tsim nyog los ntawm qee cov ntaub ntawv hais txog cov. Kab lus no muab qee cov ntaub ntawv tseem ceeb txog ob hom hauv cov ntsiab lus thiab thaum kawg cia tus nyeem ntawv mus txog qhov sib txawv tseem ceeb ntawm qhov yooj yim thiab qhov muag sib xyaw.
Qhov muag yooj yim yog dab tsi?
Txawm hais tias lub npe qhia qee qhov yooj yim, qhov muag yooj yim tsis yooj yim hauv photosensitivity thiab raug tab sis tsuas yog hauv cov qauv. Qhov muag yooj yim pom muaj nyob rau hauv ntau phyla ntawm tsiaj lub nceeg vaj nrog rau cov vertebrates thiab invertebrates. Muaj ob peb hom qhov muag yooj yim hu ua Pit eye, Spherical lens ob lub qhov muag, Ntau lub lenses, Refractive cornea, thiab Reflector ob lub qhov muag. Qhov muag qhov muag yog qhov tseem ceeb tshaj plaws ntawm txhua yam ntawm lub qhov muag, thiab muaj kev nyuaj siab me me nrog kev sau ntawm photoreception hlwb. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov vipers muaj qhov qhov muag kom paub qhov hluav taws xob infrared ntawm lawv cov tsiaj nyeg. Lub qhov muag spherical lub qhov muag muaj lub lens nyob rau hauv cov qauv, tab sis lub focal point feem ntau yog tom qab lub retina, ua rau pom qhov muag plooj kom pom qhov siv ntawm lub teeb. Ntau lo ntsiab muag yooj yim ob lub qhov muag yog ib hom kev nthuav dav nrog ntau dua ib lub lens hauv lub qhov muag, uas ua rau lawv nthuav cov duab thiab tau txais cov duab ntse thiab tsom. Qee cov tsiaj txhu xws li kab laug sab thiab eagles yog cov qauv zoo rau hom kev teeb tsa no. Lub qhov muag nrog lub pob zeb refractive muaj ib txheej txheej ntawm lub teeb nkag mus rau hauv lub teeb, thiab lub lens feem ntau tsis yog spherical, tab sis nws cov duab tuaj yeem hloov pauv raws li qhov ntev ntawm focal ntev. Reflector ob lub qhov muag yog qhov tshwm sim zoo heev uas muab kev sib txuas lus sib txuas rau lwm yam kab mob, thiab. Cov duab tsim nyob rau hauv ib lub qhov muag yog reflected mus rau lwm qhov chaw kom lwm yam kab mob tuaj yeem pom nws. Txhua yam ntawm qhov muag yooj yim no ua haujlwm hauv kev noj cov ntaub ntawv hais txog lub teeb kom txhawb nqa lub cev. Txawm tias tag nrho cov no yog qhov muag yooj yim, tag nrho cov vertebrates siab dua nrog rau tib neeg muaj qhov muag yooj yim.
Qhov muag yog dab tsi?
Compound ob lub qhov muag yog tsim los ntawm kev rov ua tib yam ntawm cov khoom siv photoreceptors hu ua ommatidia. Ib qho ommatidium muaj lub lens thiab photoreceptive hlwb feem ntau, thiab cov pigment hlwb cais txhua ommatidium sib nrug ntawm cov neeg nyob ze. Txawm li cas los xij, ob lub qhov muag muaj peev xwm tshawb pom cov lus tsa suab zoo li polarization ntawm lub hnub ci, ntxiv rau qhov tau txais lub teeb. Cov kab, tshwj xeeb tshaj yog honeybees muaj peev xwm nkag siab lub sij hawm ntawm hnub siv lub polarization ntawm lub hnub ci los ntawm lawv ob lub qhov muag. Muaj ob peb hom kev sib xyaw qhov muag hu ua Apposition, Superposition, Parabolic ncua kev kawm, thiab qee yam ntxiv. Cov ntaub ntawv hais txog cov dluab yog tsim los ntawm ommatidiais coj mus rau hauv lub hlwb, thiab tag nrho cov duab yog ua ke nyob rau hauv thiaj li yuav to taub cov khoom nyob rau hauv lub apposition ob lub qhov muag. Lub qhov muag superposition tsim cov duab los ntawm kev cuam tshuam lossis cuam tshuam lub teeb tau txais los ntawm iav lossis lo ntsiab muag, thiab tom qab ntawd cov duab cov ntaub ntawv raug xa mus rau hauv lub hlwb, kom nkag siab txog cov khoom. Parabolic suspension ob lub qhov muag siv cov ntsiab lus ntawm ob qho tib si apposition thiab superposition ob lub qhov muag. Feem ntau ntawm cov annelids, arthropods, thiab molluscs muaj ob lub qhov muag, thiab lawv tuaj yeem pom cov xim, thiab.
Qhov txawv ntawm Qhov Muag Yooj Yim thiab Qhov Muag Pom Zoo yog dab tsi?
• Ob lub qhov muag yog tsim los ntawm pawg ntawm ommatidia, tab sis qhov muag yooj yim yog tsim los ntawm tib lub qhov muag xwb.
• Cov qhov muag muaj nyob hauv feem ntau ntawm cov arthropods, annelids thiab molluscs. Txawm li cas los xij, qhov muag yooj yim pom muaj ntau hom kab mob nrog rau feem ntau ntawm cov vertebrates siab dua.
• Ob lub qhov muag tuaj yeem npog lub kaum sab xis dav dua piv rau qhov muag yooj yim.
• Hom ob lub qhov muag yooj yim muaj ntau haiv neeg ntau dua li qhov muag sib xyaw.
• Lub hnub ci polarization tuaj yeem nkag siab ntawm ob lub qhov muag, tab sis tsis yog los ntawm qhov muag yooj yim.
