Cov tawv nqaij muaj peb txheej: Tus daim tawv nqaij , txheej txheej ntawm daim tawv nqaij sab nraud, muab cov thaiv dej tsis zoo thiab tsim peb cov tawv nqaij. Cov daim tawv nqaij , sub sub daim tawv nqaij , muaj cov tawv nqaij sib txuas, cov hauv paus plaub hau , thiab cov qog tawm hws . Qhov tob subcutaneous cov ntaub so ntswg (hypodermis) yog ua los ntawm cov rog thiab cov ntaub so ntswg sib txuas.
Hauv qhov no, tus qauv thiab kev ua haujlwm ntawm daim tawv nqaij yog dab tsi?
Cov tawv nqaij1 yog ib qho ntawm cov kabmob loj tshaj plaws hauv lub cev hauv thaj chaw thiab qhov hnyav. Cov tawv nqaij muaj ob txheej: tus daim tawv nqaij thiab cov dermis . Hauv qab daim tawv nqaij lus dag hypodermis los yog subcutaneous fatty ntaub so ntswg. Cov tawv nqaij muaj peb lub luag haujlwm tseem ceeb: tiv thaiv, tswj hwm thiab hnov qab.
Kuj Paub, 7 txheej ntawm daim tawv nqaij yog dab tsi? Qauv
- Epidermis.
- Dermis.
- Cov ntaub so ntswg subcutaneous.
- Hla ntu.
- Cov tawv nqaij xim.
- Laus.
- Daim tawv nqaij flora.
- Kev tu cev thiab tu tawv nqaij.
Ua li no, tus qauv ntawm tib neeg daim tawv nqaij yog dab tsi?
Cov tawv nqaij yog tsim los ntawm ob txheej txheej tseem ceeb: lub daim tawv nqaij , ua los ntawm cov kab mob epithelial zoo sib xws, thiab cov dermis , ua los ntawm ntom, tsis xwm yeem cov ntaub so ntswg sib txuas uas ua rau cov hlab ntsha, cov hauv paus plaub hau, cov qog tawm hws , thiab lwm yam kev teeb tsa.
Dab tsi tsis yog ib feem ntawm cov qauv ntawm daim tawv nqaij?
Cov ntaub so ntswg subcutaneous (tseem yog hypodermis) yog tsis yog ib feem ntawm tawv nqaij , thiab nyob hauv qab lub dermis. Nws lub hom phiaj yog muab daim ntawv tawv nqaij mus rau cov pob txha thiab cov leeg thiab muab nws nrog cov hlab ntsha thiab cov hlab ntsha. Nws muaj cov ntaub so ntswg sib txuas xoob thiab elastin.

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 cov txheej txheem txheej txheem ntawm cov pob txha ua los ntawm?
Cov txheej txheem sab nraud, uas yog ua los ntawm cov organic matrix (30%) muaj cov proteoglycans (tab sis tsawg dua pob txha mos), glycosaminoglycans, glycoproteins, osteonectin (thauj cov pob txha pob txha mus rau collagen) thiab osteocalcin (calcium khi protein)
Dab tsi yog txheej txheej txheej hauv qab ntawm daim tawv nqaij?
Lub hauv paus txheej yog txheej txheej sab hauv ntawm txheej txheej, thiab muaj cov kab puag ncig me me hu ua basal cells. Cov hlwb basal txuas ntxiv sib faib, thiab cov hlwb tshiab tas li thawb cov laus mus rau ntawm daim tawv nqaij, qhov twg lawv thiaj li poob
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
Cov kauj ruam hauv cov txheej txheem txheej txheem txheej txheem mob yog dab tsi?
Cov ntsiab lus hauv cov txheej txheem no (8) ua kom cov vascular endothelium. vasodilation. ua npaws ntau lawm. tsiv teb tsaws ntawm cov kab mob tiv thaiv kab mob hlwb mus rau thaj chaw. ua kom thiab cytokine tso tawm los ntawm neutrophils. phagocytosis thiab cov hau kev ntawm kev puas tsuaj. tus mob theem teb. clotting cascade
