Tib neeg kev txiav txim zoo hauv nruab nrog cev thiab cov kev khiav dej num

Tsis totaub ntawm tus txiv neej yog rau nws cov sis raug zoo nrog cov sab nraum lub ntiaj teb no. Lawv muaj tsib neeg:

- qhov hloov ntawm lub zeem muag - ob lub qhov muag;

- qhov hloov ntawm lub rooj sib hais - lawv pob ntseg;

- tsis hnov tsw - lub qhov ntswg;

- kov - tawv;

- saj - lus.

Lawv tag nrho cov li cas rau lwm stimuli.

Cov kabmob ntawm saj

Txiv neej cov yam ntxwv saj. Qhov no yog vim tshwj xeeb hlwb uas yog lub luag hauj lwm rau saj. Lawv muaj nyob rau hauv tus nplaig thiab sib sau ua ke nyob rau hauv cov saj buds, txhua tus uas muaj ntawm 30 thiab 80 hlwb.

Cov saj buds nyob rau hauv tus nplaig raws li ib feem ntawm mushroom-zoo li tus papillae, uas them tag nrho saum npoo ntawm tus nplaig.

Nyob rau hauv cov lus muaj lwm yam buds uas paub txog ntau yam. Muaj ob peb hom ua kom pom tseeb, txhua tus uas distinguishes ntawm "koj" tastes.

Piv txwv li, ib tug qab ntsev thiab qab zib thiab txiav txim seb qhov ntxeev ntawm tus nplaig, iab - nws puag, thiab qaub - sab saum npoo av.

olfactory hloov khoom nruab nrog

Olfactory hlwb yog nyob rau hauv lub qaum nyo hau. Ntau microparticles poob mus rau hauv lub qhov ntswg nqe vaj lug kub rau cov qog ua kua week, yog li tuaj mus rau hauv kev sib cuag nrog lub hlwb lub luag hauj lwm rau qhov kev txiav txim ntawm tsis hnov tsw. Qhov no yog facilitated los ntawm tshwj xeeb cov plaub mos mos uas yog thicker hnoos qeev.

Mob, tactile thiab kub rhiab heev

Kuv paub ib tug neeg ntawm no zoo tseem ceeb heev, vim hais tias nws tso cai rau koj los mus tiv thaiv tiv thaiv ntau yam kev piam sij ntawm lub ntiaj teb no.

Tshwj xeeb receptors tawg khiav ri niab mus thoob plaws peb lub cev nto. Nyob rau txias reacted Kholodov, cua sov - lub tshav kub, tus mob - lub mob, kov - tactile.

Feem ntau cov tactile receptors nyob rau hauv lub cheeb tsam ntawm ob daim di ncauj thiab nyob rau hauv cov ntsis ntiv tes. Nyob rau hauv lwm qhov chaw ntawm lub cev xws li receptors tsawg npaum li cas.

Thaum koj kov ib yam dabtsi, khaus tactile receptors. Ib txhia ntawm lawv muaj ntau, lwm leej lwm tus - tsawg, tiam sis tus sau cov ntaub ntawv xa tuaj mus rau lub hlwb thiab analyzed.

pom

Tib neeg tsis totaub xws li loj lub cev - pom, ua tsaug rau uas peb tau yuav luag 80% ntawm tag nrho cov ntaub ntawv hais txog lub ntiaj teb sab nraum. Qhov muag, oculomotor nqaij, lacrimal apparatus, thiab lwm yam -. Yog hais txog qhov hloov ntawm lub zeem muag.

Lub ceev ceev muaj ib tug ob peb zoo li:

- sclera, hu ua lub cornea;

- choroid, dua nyob rau hauv pem hauv ntej ntawm lub iris.

Ceev ceev hauv yog muab faib ua ib tug chamber sau nrog ib tug pob tshab jelly zoo li txheem. Cov koob yees duab puag ncig lub lens - pob tshab disc rau saib tej khoom uas nyob ze thiab nyob deb deb.

Lub sab hauv sab ntawm lub ceev ceev, uas yog opposite rau hauv iris thiab cornea, yog lub teeb-sensitive hlwb (rods thiab cones), uas hloov lub teeb fluxes rau hauv ib qho hluav taws xob lub teeb liab nkag mus rau lub hlwb los ntawm lub optic paj.

Lacrimal apparatus yog npaj los tiv thaiv lub cornea los ntawm microbes. Lacrimal kua yog tsis tu ncua kom thiab moisturizes ntawm qhov chaw ntawm lub cornea, muab nws sterility. Qhov no yog facilitated los nyob blinking cov plaub muag.

lub rooj sib hais

Muaj xws li tib neeg tsis totaub ntawm lub rooj sib hais hloov khoom nruab nrog muaj peb yam - lub puab, theem nrab thiab txheej pob ntseg. Cov yav tas - ib tug dab ntxuav tes thiab hnov pob ntseg kwg deg. Tseg nruas ntsej cais nruab nrab pob ntseg, uas yog ib tug me me qhov chaw ntawm hais txog ib tug nyhav centimeter.

Lub nruas ntsej thiab cov inner pob ntseg zais ib tug peb me me pob txha, hu ua "rauj", "txoj hlua eeb nees" thiab "thaiv", uas muab cov kev hloov ntawm lub suab deeg los ntawm lub nruas ntsej rau cov inner pob ntseg. Zvukovosprinimayuschego lub cev yog lub qwj, uas yog nyob rau hauv lub inner pob ntseg.

Qwj yog ib tug me me raj, spirally cov tsim ob thiab ib tug ib nrab puv tshwj xeeb. Nws yog lawm ua tus sau nrog ib tug khov kua. Thaum tau txais daim ntawv ntawm lub suab deeg mus rau lub inner pob ntseg kua dhau, uas sways thiab ua rau piav thoob hlo plaub mos mos. Cov ntaub ntawv nyob rau hauv daim ntawv ntawm cov pulses xa mus rau lub hlwb yog analyzed, thiab peb tau hnov lub suab.
