Feem ntau pom daim tawv nqaij appendages yog:
- Cov hauv paus plaub hau.
- Cov qog sebaceous.
- Apocrine hws qog.
- Eccrine qog hws.
- Ntsia.
Yooj yim li ntawd, muaj pes tsawg daim tawv nqaij ntxiv?
4 Appendages . Daim tawv nqaij appendages (xws li cov hauv paus plaub hau) tau muab los ntawm cov ntaub so ntswg epidermal thiab feem ntau pom pom qhov tob tob rau hauv daim tawv nqaij.
Tsis tas li ntawd, dab tsi appendages pom nyob rau hauv lub dermis? Epidermal Appendages
- Cov qog sebaceous.
- Cov qog tawm hws.
- Apocrine qog.
- Cov qog mammary.
- Cov hauv paus plaub hau.
Tsuas yog li ntawd, 4 appendages ntawm daim tawv nqaij yog dab tsi?
Cov qauv no, hu ua "daim tawv nqaij appendages," tuaj yeem muab faib ua plaub pawg: cov qog tawm hws (eccrine thiab apocrine), cov qog sebaceous , plaub hau thiab tes.
Cov khaubncaws sab nraud povtseg thiab cov ntawv sib txuas ntawm daim tawv nqaij puas muaj kev faib cov cell?
Lub hauv paus epithelial sheath thins thaum nws mus rau lub teeb plaub hau kom tsuas yog ib txheej ntawm cov kab mob epidermal tseem nyob ua kab papillae: cov cell ntawm stratum germinativum . Cov hlwb no nquag faib thiab tsim cov plaub hau.

Dab tsi yog txheej txheej sab saum toj ntawm daim tawv nqaij nyob ib sab ntawm daim tawv nqaij?
Lub dermis txuas cov epidermis mus rau hypodermis, thiab muab lub zog thiab kev ywj pheej vim muaj cov collagen thiab elastin fibers. 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 ntawm cov ntaub so ntswg sib txuas tsis tu ncua thiab cov ntaub so ntswg sib txuas tsis sib xws?
Cov ntaub so ntswg sib txuas tsis sib thooj muaj cov fibers uas tsis tau sib dhos ua ke zoo ib yam li cov ntaub so ntswg sib txuas ib ntus. Cov ntaub so ntswg sib txuas tsis sib thooj muaj feem ntau ntawm cov fibers collagen. Nws muaj cov khoom hauv av tsawg dua li cov ntaub so ntswg sib txuas
Dab tsi yog qhov sib txawv tseem ceeb ntawm cov tawv nqaij sib txuas thiab cov fibrous?
Muaj ntau hom ntaub so ntswg sib txuas. Ib hom yog cov ntaub so ntswg sib txuas ua ke, tseem hu ua cov ntaub so ntswg sib txuas. Lub ntsiab lus fibrous thiab qhov sib txawv tuaj vim tias cov ntaub so ntswg sib txuas tau ua los ntawm cov fibers. Cov fibers feem ntau yog ua los ntawm collagen ntxiv rau qee qhov fibroblasts
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?
Dermatitis yog lo lus dav dav uas piav txog kev ua rau tawv nqaij. Dermatitis yog ib yam mob uas muaj ntau yam ua rau thiab tshwm sim ntau yam. Nws feem ntau yog khaus, tawv nqaij qhuav los yog pob khaus ntawm daim tawv nqaij o, reddened
