Peb cov yam ntxwv ntawm cov ntaub so ntswg sib txuas yog tias lawv tau vascularized heev, lawv rov zoo los ntawm kev puas tsuaj thiab lawv muaj ntau cov khoom siv tsis yog ntawm tes. Piv txwv ntawm tshwj xeeb cov ntaub so ntswg sib txuas suav nrog ntshav, pob txha, pob txha mos thiab lymphoid cov ntaub so ntswg.
Raws li, dab tsi yog 3 yam ntxwv ntawm cov ntaub so ntswg sib txuas?
Cov ntaub so ntswg sib txuas muaj peb yam tseem ceeb: hlwb fiber, thiab cov khoom hauv av. Ua ke cov khoom hauv av thiab cov fibers ua cov txheej txheem sab nrauv. Cov ntaub so ntswg sib txuas tau muab cais ua ob hom: mos thiab tshwj xeeb cov ntaub so ntswg sib txuas.
Tsis tas li ntawd, txoj haujlwm dav dav ntawm cov nqaij sib txuas yog dab tsi? Lub luag haujlwm tseem ceeb ntawm cov ntaub so ntswg sib txuas suav nrog: 1) khi thiab txhawb nqa, 2) tiv thaiv, 3) rwb thaiv tsev, 4) khaws cia roj cia, thiab 5) thauj cov tshuaj hauv lub cev. Cov ntaub so ntswg sib txuas tuaj yeem muaj ntau qib vascularity. Cov pob txha mos yog avascular, thaum ntom cov ntaub so ntswg sib txuas tsis zoo vascularized.
Ib qho ntxiv, dab tsi yog cov yam ntxwv dav ntawm cov ntaub so ntswg sib txuas?
Qhia peb yam tseem ceeb: (1) tshwj xeeb hlwb , (2) cov nqaij protein ntau ntxiv thiab (3) cov kua uas paub tias yog cov khoom hauv av. Cov kua dej sab nraud thiab cov khoom hauv av ua haujlwm suav nrog cov lej uas nyob ib puag ncig hlwb , suav rau feem ntau ntawm cov nqaij ntim thiab txiav txim siab ua haujlwm tshwj xeeb.
Cov yam ntxwv zoo li cas rau txhua cov ntaub so ntswg sib txuas?
Cov ntaub so ntswg sib txuas tuaj hauv ntau hom ntawv, tab sis lawv ib txwm muaj nyob hauv peb yam yam ntxwv tshwj xeeb: hlwb , cov khoom loj hauv av amorphous, thiab cov protein ntau.

Dab tsi yog 3 yam ntawm cov ntaub so ntswg sib txuas ua los ntawm fibroblasts?
Peb hom tseem ceeb ntawm cov fibers yog zais los ntawm fibroblasts: collagen fibers, elastic fibers, thiab reticular fibers
Peb yam ntxwv ntawm cov ntaub so ntswg sib txuas yog dab tsi?
Peb yam ntxwv ntawm cov ntaub so ntswg sib txuas yog tias lawv tau vascularized heev, lawv rov zoo los ntawm kev puas tsuaj thiab lawv muaj ntau cov khoom siv tsis yog ntawm tes. Piv txwv ntawm cov ntaub so ntswg tshwj xeeb suav nrog ntshav, pob txha, pob txha mos thiab cov nqaij mos lymphoid
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
Cov yam ntxwv ntawm cov ntaub so ntswg sib txuas yog dab tsi?
Cov ntaub so ntswg sib txuas ua ke muaj zog, ua cov hlua zoo li cov leeg thiab cov leeg. Tendons txuas skeletal leeg rau cov pob txha; ligaments txuas cov pob txha rau cov pob txha ntawm cov pob qij txha. Ligaments muaj qhov ncab ntau dua thiab muaj cov ywj ywj ntau dua li cov leeg
Hom ntaub so ntswg sib txuas twg yog cov ntaub so ntswg?
Cov ntaub so ntswg reticular yog ib hom tshwj xeeb ntawm cov ntaub so ntswg sib txuas uas muaj nyob hauv ntau qhov chaw uas muaj cov ntsiab lus ntawm tes. Nws muaj ib tug ceg thiab mesh-zoo li tus qauv, feem ntau hu ua reticulum, vim yog kev npaj ntawm reticular fibers (reticulin). Cov fibers no yeej yog hom III collagen fibrils
