Nws kuj tseem muaj cov neeg siv tshuab ua haujlwm uas muab kev nkag siab zoo thiab cov thermoreceptors uas muab kev nkag siab ntawm tshav kub.
Hauv qhov no, dab tsi ua rau feem ntau ntawm daim tawv nqaij?
Cov daim tawv nqaij muaj ob txheej: Hauv txhais tes thiab taw, tus tawv nqaij papillae tsim cov kab mob ntawm daim tawv nqaij (hws los ntawm daim tawv nqaij ntawm daim tawv nqaij tawm cov ntiv tes). Cov txheej txheem reticular yog txheej tuab ntawm cov tawv nqaij sib txuas tsis sib xws. Nws dag tob rau txheej txheej papillary thiab ua rau feem ntau ntawm cov tawv nqaij.
Qhov thib ob, puas yog daim tawv nqaij muaj cov nqaij sib txuas? Cov daim tawv nqaij muaj cov hlab ntsha, cov ntaub so ntswg sib txuas , lub paj hlwb, cov hlab ntshav, cov qog, cov txais, cov plaub hau. Cov dermis muaj ob peb cov qog tseem ceeb.

Ntawm no, dab tsi ua rau 70 feem pua ntawm daim tawv nqaij?
Cov daim tawv nqaij yog qhov twg collagen thiab elastin tau pom, uas yog ib qho laj thawj nws yog lub hom phiaj xav tau rau feem ntau ntawm cov khoom xyaw nquag pom hauv cov khoom kom zoo nkauj. Qhov tseeb, cov protein collagen ua rau 70 feem pua ntawm cov tawv nqaij . Nws yog cov ntim ntim ntau, zoo ib yam li Styrofoam peb siv los ntim cov khoom tsis zoo.
Lub luag haujlwm tseem ceeb ntawm daim tawv nqaij yog dab tsi?
"Dermis" yog txheej txheej nyob tawv nqaij . Nws tau muab faib ua thaj av papillary thiab thaj chaw reticular. Lub luag haujlwm tseem ceeb ntawm daim tawv nqaij yog txhawm rau lub cev los ntawm kev ntxhov siab thiab kev nyuaj siab, thiab muab: elasticity rau tawv nqaij , kev nkag siab ntawm qhov kov, thiab cua sov.

Nws tsuas muaj ob txheej: txheej txheej papillary nrog papillae uas nthuav mus rau hauv daim tawv nqaij thiab qis dua, txheej txheej reticular uas muaj cov ntaub so ntswg sib txuas xoob
Dab tsi yog qhov sib txawv tseem ceeb ntawm lub hauv paus paj hlwb thiab lub paj hlwb sab hauv?

Dab tsi yog qhov txawv ntawm daim tawv nqaij thiab daim tawv nqaij daim ntawv xeem?
Qauv: Sib sib zog nqus ntawm daim tawv nqaij; connective ntaub so ntswg muaj li ntawm ob txheej. Muaj nuj nqi: Muaj lub luag haujlwm rau cov txheej txheem muaj zog thiab yoog raws ntawm daim tawv nqaij; lub epidermis pauv cov pa roj, cov khoom noj, thiab cov khoom pov tseg nrog cov hlab ntsha hauv lub dermis
Puas yog lo lus dav dav txhais tau tias yog mob ntawm daim tawv nqaij lossis pob khaus uas tuaj yeem muaj ntau yam ua rau nws yog ib qho cim ntawm ntau hom tawv nqaij tsis xws luag?
