Zonule, feem ntau hu ua ciliary zonule, yog lub voj voog ncig lub cev uas txuas lub lens ntawm lub qhov muag mus rau lub cev ciliary. Lub zonule yog tsim los ntawm ib qho txheej txheem ntawm cov fibers uas nthuav dav qhov sib txawv ntawm lub lens thiab cov uas nyob ib sab uas tsis yog xim ciliary epithelium (NPCE)
Zone yog dab tsi?
Zonules (ntawm Zinn) yog lub nplhaib ntawm cov fibers, tsim los ntawm elastin microfibrils, uas txuas ntawm lub cev cilary mus rau qhov sib npaug ntawm lub lens capsule thiab yog li ncua. lub lens nyob rau hauv qhov chaw.
Zoo ntawm qhov muag yog dab tsi?
Ciliary zonules yog lub nplhaib ntawm cov qauv fibrous anchoring lub ciliary lub cev nrog lub lens ntawm lub qhov muag. Cov no yog cov qauv uas pab tswj txoj haujlwm ntawm lub lens nyob rau hauv txoj kev kho qhov muag, thiab cov leeg thauj tog rau nkoj uas hloov cov duab ntawm lub lens hloov kom pom tseeb.
lens zonules nyob qhov twg?
Zonular fibers thauj tog rau nkoj qhov sib npaug ntawm lub lens thiab nyob ib sab anterior thiab posterior nto ntawm lub lens rau ciliary lub cev thiab thiab ciliary ib feem ntawm lub retina. Cov ciliary epithelial hlwb ntawm lub qhov muag tej zaum ua ke ntawm cov zonules.
Zonular fibers yog dab tsi?
Cov zonules yog cov xov zoo li cov xov me me uas tuav lub qhov muag lub qhov muag kom ruaj khov nyob rau hauv qhov chaw Cov zonules kuj ua haujlwm nrog cov leeg ciliary los pab lub lens haum (hloov tsom xam). Lub zonule fibers nruj thiab rub lub lens kom ze rau qhov pom. Lawv so raws li lub lens flattens rau kev pom kev deb.

Tsis muaj O 2 (hypoxia) yog qhov kev txhawb nqa rau kev sib txuas ntawm erythropoietin (Epo), feem ntau hauv ob lub raum. Epo yog qhov muaj sia nyob, kev loj hlob thiab qhov sib txawv rau cov erythrocytic progenitors, tshwj xeeb tshaj yog cov colony-forming units-erythroid (CFU-Es) .
Nyob rau hauv endochondral ossification dab tsi tshwm sim rau cov chondrocytes?
YNyob rau hauv endochondral ossification, ua li cas rau cov chondrocytes? Lawv tuag nyob rau hauv lub calcified matrix uas nyob ib puag ncig lawv. Lawv pab pawg ua ke los tsim thawj qhov chaw ossification chaw ossification chaw Ib qho chaw ossification yog ib qho chaw uas ossification ntawm pob txha mos pib Thawj kauj ruam hauv ossification yog tias cov pob txha mos ntawm lub sijhawm no nthuav dav thiab npaj lawv tus kheej hauv kab.
Cov qauv thiab cov qauv rau cov kws qhia ntawv yog dab tsi?
Cov Qauv thiab Cov Qauv rau Cov Kws Qhia Ntawv (NSE) siv ib qho txiaj ntsig raws li txoj hauv kev rau cov kws qhia ntawvthiab muab cov lus piav qhia ntxaws txog qhov uas tus kws qhia ntawv muaj peev xwm ua tau. Qhov tseem ceeb ntawm txoj cai yog kev ua tau zoo hauv cov tsev kawm ntawv, chav kawm, kev tswj hwm thiab kev txhawb nqa ntawm lub tsev kawm ntawv .
