Ukuhlaziya ezishukumisa ezibukwayo kwenzeka e-receptor: izinto ezithakazelisayo kakhulu mayelana nale nqubo

Ukuhlaziya ezishukumisa ezibukwayo ithatha indawo la mangqamuzana. Okuningi ngokunembile, khona-ke iqala. Khona-ke kukhona namanje izinqubo eziningi ezihlobene ukuhlaziywa. Ngokuvamile, konke okwenzekayo emzimbeni womuntu - kungcono kakhulu. Futhi le timu iyathinteka. Ngakho aholele ukukhuluma ngakho ngokuningiliziwe.

imiqondo

Ngakho-ke ngaphambi ukutshela lapho ukuhlaziya ezishukumisa ezibukwayo, singathanda uthinte imiqondo ngokwabo. Ngakho, ngokusebenzisa izinzwa ngqo cortex cerebral njalo bondliwa ulwazi. Lokhu akuyona into ngomzuzwana - ngokuqhubekayo. Ngo izingxenye ezisele cortex uthola amaza ivela ezingxenyeni ezihlukahlukene zomzimba. Futhi yiluphi ulwazi nokushukunyiswa kuthiwa bahlolisisa ngokucophelela. Kubalulekile umsebenzi ngokugcwele emzimbeni womuntu.

Ngakho, ukuhlaziywa ezishukumisa ezibukwayo kwenzeka receptor, ngamunye qembu kunokwaziswa okubucayi ofuna ukukudlulisela ehluke ngokuphelele. Yini-ke, uma sikhuluma ngeso? Ngokwemvelo ezibukwayo, kahle receptor aphendule ogxile umbala nokukhanya.

Kwake kwathi ngo-la mangqamuzana avele amaza, bona adlule izinzwa afferent, okuyinto awela ngaphasi kwehlelo isimiso sezinzwa esiyinhloko. Futhi ke bayaba endaweni yabo ehambisana of the cortex.

uhlaka umbono

Wonke umuntu uyazi ukuthi umzimba indoda futhi yimuphi omunye izidalwa eziphilayo kuyinto iso. Okuningi ngokunembile, kuba igama layo eyayivame. Eqinisweni, it siqukethe yeso futhi apharathasi asizayo. Sinenkosi umsebenzi wabo siqu. Futhi yeso wenza ebaluleke kakhulu, eqinisweni kuba ingxenye neuropathy yazo zonke analyzers.

Kuboshwe umfundi - into yokuqala Ngithanda ukuziqhakambisa, ukhuluma ngani ukuhlaziywa ezishukumisa ezibukwayo. Senzeka Umfundi ukukhanya ukumuncwa inqubo. Kungenxa imisebe yakhe awela iso. Kukhona i-retina, kukhona isakhiwo ziyinkimbinkimbi kakhulu futhi ethambile. Futhi phezu kwalo kukhona izinduku kanye Izigaxa (lokhu amaseli ukukhanya-sensitive). Futhi kusukela amaseli bese amahlamvu ngqo emsipheni. Yena - lena ekuqaleni conduction we analyzer.

kwalungiswa izinkunga zokubona

Ngakho, ngemva ukudlula imishayo ukukhanya ngokusebenzisa i-cornea kanye ketshezi aqueous, iqala ukuhlaziywa ezishukumisa ezibukwayo. Senzeka lens, bese ugelezela Vitreous. Konke lokhu kungenxa uhlelo optical we iso, okuyinto refracts imisebe, bese eqoqa kubo kakade kuyi-retina.

Futhi ezithakazelisayo kuyinqubo ngesikhathi lapho isithombe bese ihlaziya. Ngakho, imisebe uyeza, eqinisweni, amaphuzu amabili okufanayo, refracted futhi uboniswa kuyi-retina. Kodwa sibheke phansi (uma sikhuluma ngolimi olulula). Kodwa-ke futhi bona idlule zemizwa ubuchopho bethu iza seyihleliwe kanye nabokhulumile emuva ulwazi (image).

Kwenzeka konke lens eguqa. Ngenxa yalokhu, lesi sithombe bese ziphenywe. Kubalulekile ukwazi ukuthi lens futhi retina - ingxenye zintekenteke kakhulu yesimiso sethu optical futhi isici kancane kungaholela ukungalingani ecacile. Ngenxa yalokhu, isithombe kungenziwa igxile akunjalo ezingacacile kakhulu, ngisho emva retina. Lena kude-okwesa-. Lapho isithombe ugxile ngaphambi kwe-retina - okungukuthi, ngokulandelana, okufutshane-okwesa-.

Izinduku kanye Izigaxa

Kulaba ama-receptor kushiwo ngenhla. Ukuhlaziya ezishukumisa ezibukwayo kwenzeka kuzo, futhi. Chopsticks abizwa ngokuthi Ubuningi bamahora nozwelo ukukhanya receptor ngemisebe. Kubo, umfutho kungaba ngisho ababuthakathaka twilight ukukhanyisa. Nokho, abazange baphendule umbala. Yileyo Eqinisweni, kwezinye shades lezinto ngesineke. It izinti zisetshenziswa okwamanje, lapho indoda eyayihamba ngomgwaqo omnyama ukuhlukanisa Silhouettes izimoto, izindlu kanye nabanye abantu, kodwa ungakwazi ukuphendula umbuzo othi: yini umbala - maroon, blue, noma emnyama?

Izigaxa, njengoba ungase ukuqagela, ingazikhathaleli ukukhanya. Kodwa sibonga kubo, thina ukuhlukanisa phakathi imibala kanye shades. Ziyakwazi phambi umfundi. Njengoba bekhula, inani Izigaxa uyanda futhi uya ngokuya ziba namandla, lokhu upha kangangokuthi umuntu aze ukuvuthwa, ungakwazi ukuhlukanisa imibala xaxa kanye shades.

lithathelwe

Lona omunye iphuzu ukuthi ngingathanda ukukhulisa ukunakwa, ukhuluma ngani ukuhlaziywa ezishukumisa ezibukwayo. Senzeka ohlelweni olufanayo optical. Ukuzijwayeza - kuyinto amehlo umlutha sicondze eziyizungezile emazingeni ehlukene ukukhanya. Ngokwesibonelo, uma umuntu ohlezi ebusuku ekhaya, bese ngokuzumayo izibani ukuphuma, kwaba isikhathi impela sengathi abayizimpumputhe. Nokho, ngemva umzuzu noma emibili eqala ukuhlukanisa wabuka lezinto ke, bajwayele, futhi akazange sicale kubona kutsi okuhambisana nakho. Have ihora ukuchitha ebumnyameni, kungenzeka ukwandisa abe nozwela amehlo akho izikhathi ezingaphezu kwamakhulu amabili! Njalo is ukuhlaziywa eqondile ezishukumisa ezibukwayo.

Kuvela ku emsipheni optic imayelana okufanayo, nalapho umuntu ephuma ebumnyameni ekamelweni ngokukhazimulayo ovuthayo. Bese kukhona izindawo zokuhlala. Lena inqubo lapho amehlo ingashintshwa ukuhlukanisa izinto at amabanga ehlukene.

Ngokuvamile ohlelweni lwethu optical kuyinqubo uyaca. Ayikho isithakazelo kancane iyona ukubona eduze futhi ezikude, ezifana umbala ubumpumputhe, nokunye. D. Nokho, lokhu kuyinto isihloko ubanzi kakhulu futhi yehlukene kaningi okubalwa futhi kufanele kakade ukukhuluma ngokwehlukana.
