Cov txheej txheem txheej txheem yog nyob ntawm lub vertebral koov ntawm kev sib tshuam ntawm pedicles thiab lamina. Ib qho cranial txheej txheem articular koom nrog caudal txheej txheem articular los ntawm lub vertebra nyob tam sim cranially los ua ib qho txheej txheem txheej txheem sib koom ua ke (Daim duab 3-4).
Hauv qhov no, qhov txheej txheem ua haujlwm tsis zoo nyob qhov twg?
Cov cov txheej txheem qis dua khiav downward thiab me ntsis tom qab los ntawm laminae. Lawv kab mob nto ntsej muag ventrolaterally rau lub superior articular facets ntawm vertebrae hauv qab lawv. Cov kab mob lub dav hlau yog curvilinear.
Qhov thib ob, dab tsi yog txheej txheem txheej txheem zoo tshaj? A txheej txheem txheej txheem zoo tshaj txuas ntxiv lossis tig ntsej muag, thiab ib qho cov txheej txheem qis dua ntsej muag los yog tej yaam num downward ntawm txhua sab ntawm ib tug vertebrae. Cov khub superior articular txheej txheem ntawm ib lub vertebra koom nrog ua ke ua ke cov txheej txheem qis dua los ntawm qhov siab dua vertebra tom ntej.
Ib yam li ib tus tuaj yeem nug, cov txheej txheem sib txuas txhais li cas?
Cov txheej txheem txheej txheem los yog zygapophyses (Greek ζυγον = "yoke" (vim nws txuas ob vertebrae) + απο = "tawm" + φυσις = " txheej txheem ") ntawm vertebra, yog projections ntawm lub vertebra uas ua hauj lwm rau lub hom phiaj ntawm haum nrog ib tug nyob ib sab vertebra. Qhov tiag cheeb tsam ntawm kev sib cuag yog npe la articular facet.
Zygapophyseal sib koom nyob qhov twg?
Zygapophyseal sib koom tes yog pob qij txha uas yog nyob nyob rau hauv nruab nrab ntawm qhov ua tau zoo dua thiab qis dua cov txheej txheem ntawm cov vertebrae uas nyob ib sab.
Pom zoo:
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)
Puas yog cov txheej txheem txheej txheem hauv metabolic suav nrog cov roj (cholesterol)?
Cov lipid vaj huam sib luag ntsuas theem ntawm: Tag Nrho Cov Cholesterol, HDL - 'Cholesterol Zoo', LDL - 'Cholesterol Tsis Zoo', thiab Triglycerides. Lub Rooj Sib Tham Cov Kab Mob Sib Luag (CMP) ntsuas cov ntshav qab zib (piam thaj) qib, cov roj ntsha thiab cov kua dej sib npaug, lub raum ua haujlwm, thiab ua haujlwm siab
Tus txheej txheem txheej txheej txheej thaum ub zoo li cas?
Kev tsim cov txheej txheem thaum ntxov hauv lub blastocyst suav nrog kev sib koom ua ke ntawm kev sib koom tes thiab rov kho cov hlwb hauv epiblast. Cells overlaying Koller Sickle nyob rau tom qab kawg ntawm tus me nyuam qaib embryo txav mus rau kab nruab nrab, sib ntsib thiab hloov kev taw qhia mus rau nruab nrab ntawm epiblast
Puas yog CPT code hais txog cov txheej txheem cais ib feem ntawm cov txheej txheem?
Tus lej CPT hais txog tus txheej txheem cais yog txheej txheem uas tau tshaj tawm yog tias nws yog qhov kev pabcuam nkaus xwb. Yog tias nws ua tiav tib lub sijhawm nrog lwm cov txheej txheem (cov lis dej num yog rau cov kev pabcuam uas tau muab ua ke), cov txheej txheem no yuav tsis raug tshaj tawm
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
