Iimpawu zengqondo zabantu kunye nemisebenzi yazo

Izitho zengqondo zabantu zenzelwe ukusebenzisana nehlabathi elijikelezile. Banabantu abahlanu:

- ilungu lombono - amehlo;

- ilungu leengxoxo - iindlebe;

- iphunga - impumlo;

- Ikhumba;

- intetho - ulwimi.

Bonke basabela kwisingeniso sangaphandle.

Amabhunga enkcazo

Ingcamango ikhethekileyo kumntu. Oku kubangelwa kwiiseli ezizodwa ezijongene nengcamango. Zilwimi kwaye zidibaniswa zibe yi-taste buds, nganye ibe neeseli ezingama-30 ukuya kuma-80.

Le mibhobho enobuncwane ifumaneka kulwimi lwe-mushroom papillae, ehlanganisa wonke umhlaba.

Ngolwimi kukho ezinye i-papillae ezibona izinto ezahlukeneyo. Kukho iintlobo ezininzi ezigxilwe kuzo, nganye ekwahlula "ingcamango" yayo.

Ngokomzekelo, isalathisi nesinambitheka sinquma isilwimi sosizi, isanti siyi siseko, kwaye umdaka lububanzi bomhlaba.

I-Organ of Smell

Iiseli ezicacileyo zifumaneka kwingxenyana yamanzi. Ama-microparticles ahlukeneyo angena kwiimpawu zomnxeba kwiimbumba ezinamaqabunga, ngenxa yokuba baqala ukudibanisa neeseli ezinoxanduva lokuvumba. Oku kukhuthazwa ngeenwele ezikhethekileyo ezibukhulu be-mucus.

Ubunzima, ubuncwane kunye nobushushu obushushu

Izitho zomzimba zendoda zibaluleke kakhulu, kuba kukuvumela ukuba uzikhusele kwiingozi ezahlukeneyo zehlabathi elijikelezile.

Iimvume ezikhethekileyo zihlakazekile emzimbeni wethu. Ubunzima buya kubanda kubanda, bushushu - bushushu, bubuhlungu, buqatha.

Iimfesane eziphathekayo zikwindawo yomlomo kunye naseminwebeni. Kwamanye amacandelo omzimba, ezo mphumela zibancinci.

Xa uthinte into ethile, i-receip receptors iyacaphuka. Ezinye zivelele, ezinye zingaphantsi, kodwa zonke iinkcukacha eziqokelelweyo zithunyelwa kwingqondo kwaye zihlalutyiweyo.

Umbono

Iimbono zomntu zibandakanya imbono ebaluleke kakhulu, apho sifumana phantse i-80% yazo zonke iinkcukacha ngehlabathi langaphandle. Iliso, izicubu ze-oculomotor, izixhobo zokudiliza, njl. Zizinto zembutho wombono.

Kwilime lemeko kukho iigobolondo eziliqela:

- i-sclera, ebizwa ngokuba yi-cornea;

- i-membrane ye-vascular ehamba ukusuka phambili ukuya kwi-iris.

I-eyeball yangaphakathi ihlukaniswe ngamagumbi agcwele i-jelly-like contents content. Iikhamera zungeze i-lens - idiski evulekileyo yokujonga izinto ezisondele kwaye zide.

Icala elingaphakathi kweso lesibini, elibhekiselele kwi-iris ne-cornea, linamaseli afanekisayo (iintonga kunye neeponsi) eziguqula umlambo okhanyayo kwisiganeko sombane ukungena kwingqondo nge-nertic optic.

I-apparatus echasayo yenzelwe ukukhusela i-cornea kwiintsholongwane. I-Lacrimal fluid iyaqhubeka iphosa kwaye iyanciphisa ummandla we-cornea, ukubonelela nge-stnea. Oku kuququzelelwe ngeefowuni ngezinye izikhathi.

Ukuva

Izitho zengqondo zomntu zibandakanya ilungu lokuphulaphula, elinamalungu amathathu-intloko yangaphakathi, ephakathi nangaphandle. Iyokugqibela igobolondo lokuphicotha kunye nomngcipheko wokuphicotha. Ukusuka kuyo i-eardrum ihlukanisa i-eardrum, eyona ndawo yincinane, umthamo we-cubic centimeter.

I-eardrum kunye neendlebe zangaphakathi zifihla ngokwabo amathambo amancinane amathathu, athi "inyundo", "isisitrasi" kunye "nesigxina", esinika ukudluliswa kwezandi ezivakalayo kwi-membrane ye-tympanic kwindlebe yangaphakathi. I-organ snoring organ iyinkukhu, ekhoyo kwindlebe yangaphakathi.

Inkukhu yincinci encinci ephothiweyo ejikelezayo ngohlobo olukhethiweyo lwesibini nengxenye. Izaliswe ngumbane ovelele. Xa ukuvakala okuvakalayo kungena kwindlebe yangaphakathi, zitshintshelwe kumbane ohambayo kwaye wenza kwizinwele ezibuhlungu. Ulwazi ngeendlela zengqondo zithunyelwa kwingqondo, zihlalutyiwe, kwaye siva izandi.
