Human pfungwa nhengo dzavo mabasa

Pfungwa dzomunhu dziri pamusoro kudyidzana dzaro kunze nyika. Vane vanhu vashanu:

- the nhengo wokuratidzwa - meso;

- the nhengo rokunzwikwa - nzeve dzavo;

- munhuhwi - yepamhino;

- Kubata - reganda;

- kuravira - mutauro.

Vose vanoita kuti zviwane.

The nhengo kuravidza

Pamunhu mamirire kuravira. Izvi imhaka mumasero anokosha kuti vane basa kuravira. Zvinowanika parurimi anoungana zvakabikwa namabukira, chimwe nechimwe chine masero pakati 30 uye 80.

Izvi ngazvirege Mafundo riri parurimi sezvo chikamu howa serin'i papillae, izvo rakafukidza pepasi rurimi.

Mumutauro pane dzimwe namabukira kuti vanoziva zvakasiyana zvinhu. Kune mhando dzakawanda nezvechii, chimwe nechimwe kusiyanisa zvadzinofarira "yenyu".

Somuenzaniso, imwe wakawanda uye zvinozipa anosarudza muromo rurimi, shungu - chawo, uye anovava - lateral penyika.

olfactory nhego

masero Olfactory vari repamusoro uta. Various microparticles kuwira nasal nendima kune mucous membranes, saka uya neZvapupu masero anokonzera kunhuhwidza. Izvi akwanise ne anokosha bvudzi kuti vari mukobvu madzihwa.

Marwadzo, tactile uye tembiricha wanda

Ini kuona munhu uyu mhando zvinokosha zvikuru, nokuti kunoita kuti kudzivirira ngozi siyana munyika.

Special receptors nakure muviri wedu pemvura. On chando akadavira Kholodov, kupisa - kupisa, marwadzo - marwadzo, kubata - tactile.

Most tactile receptors iri munharaunda nemiromo uye napamusoro nyore. Mune dzimwe nhengo dzomuviri dzakaita receptors shoma zvikuru.

Kana iwe kubata chinhu, akatsamwisa tactile receptors. Vamwe vavo vane unetseke, vamwe - zvishoma, asi vakaunganidza ruzivo rwunotumirwa uropi uye vakaongorora.

kuona

Human pfungwa zvinosanganisira chikuru muviri - kuona, nemhaka iyo isu tiwane dzinenge 80% mashoko ose pamusoro kunze nyika. Ziso, oculomotor tsandanyama, lacrimal midziyo, etc. -. Ko zvenyaya nhengo wezvakaonekwa.

Yeziso ane anoshongwa shoma:

- sclera, akadana cornea;

- choroid, vakapfuura pamberi Iris.

Yeziso mukati rakakamurwa kamuri azadzwa läpinäkyvä mondo-zvakadai mukati. Cameras vakombe izvo - läpinäkyvä Disc nokuda kuona zvinhu zviri pedyo uye kure kure.

Yomukati divi yeziso, pakatarisana kuti maziso uye cornea, chiedza-inonyatsoziva masero (pematanda uye pasikweya), izvo exchange chiedza fluxes kupinda wemagetsi mureza kusvitsa kuuropi parutivi optic etsinga.

Lacrimal midziyo rinotarisirwa kudzivirira cornea kubva tupukanana. Lacrimal Urume ndiye akaramba crow uye moisturizes pemvura cornea, ichipa wake kusabereka. Izvi akwanise ne apo neapo achibwaira eyelashes.

kunzwa

Zvinosanganisira munhu pfungwa nokunzwa nhengo zvinosanganisira zvitatu zvinoti - yomukati, pakati dzokunze nzeve. Ekupedzisira - a singi uye auditory nzeve Canal. Away eardrum anotsaura pakati nzeve, ndiro duku anenge mumwe cubic sendimita.

The eardrum uye yomukati nzeve avanze mapfupa diki matatu, anonzi "sando", "stirrup" uye "panhera", izvo zvinopa kuchinjwa inzwi vibrations kubva eardrum kusvika munzeve. Zvukovosprinimayuschego muviri ndiko nedhambakura, riri munzeve.

Snail iri chubhu duku, spirally vakamonyanisa kuumbika maviri nehafu anotendeuka inokosha. Rizere ane viscous zvokunwa. At okutambirwa inzwi vibrations kusvika munzeve Urume Apfuura, izvo ichifambisa obva kutsinga dzinouya bvudzi. Information muchimiro pulses akatumira muuropi anoongororwa, uye isu kunzwa.
