Anatomy. Cov extrapyramidal system muaj cov kab ke ntawm kev ua haujlwm cuam tshuam txog keeb kwm hauv telencephalon, diencephalon thiab midbrain. Cov hauv paus ganglia sawv cev rau qhov loj tshaj plaws, thiab suav nrog caudate, putamen thiab globus pallidus. Lub caudate nucleus nyob ntawm lub qhov tso pa tawm sab ntawm sab laug ventricle.
Ua qhov no hauv kev txiav txim siab, dab tsi suav nrog hauv basal ganglia?
Cov hauv paus ganglia yog ib pawg ntawm cov qauv pom sib sib zog nqus hauv lub paj hlwb hemispheres. Cov qauv feem ntau suav nrog hauv basal ganglia yog caudate, putamen, thiab globus pallidus hauv lub paj hlwb, qhov tseem ceeb nigra hauv nruab nrab lub paj hlwb, thiab subthalamic nucleus hauv diencephalon.
Ib yam nkaus, cov txheej txheem extrapyramidal suav nrog dab tsi? Hauv kev sib piv, cov extrapyramidal system muaj cov neurons uas pib hauv lub paj hlwb, suav nrog thaj tsam lub cev muaj zog, thiab nqis los rau hauv lub hlwb ncaj qha lossis los ntawm txoj hauv kev hauv paus (subcortical) nuclei. Synapse tshwm sim nrog cov neurons ntxiv hauv cov hauv paus hauv paus thiab lub hauv paus hlwb.
Ib tus kuj yuav nug, qhov txheej txheem extrapyramidal nyob qhov twg?
Extrapyramidal cov ntawv tseem ceeb pom hauv kev rov tsim dua ntawm cov pons thiab medulla, thiab lub hom phiaj qis lub cev muaj zog neurons hauv cov leeg txha caj qaum uas tau koom nrog hauv kev xav rov qab, kev txav chaw, kev txav mus los yooj yim, thiab kev tswj lub cev.
Puas yog basal ganglia ib feem ntawm thalamus?
Set ntawm hauv paus ganglia suav nrog nucleus caudatus, putamen, globus palidus, nigra substance, thiab subtalamus nucleus. Lawv nyob feem ntau ntawm ib sab mus rau thalamus , nyob ib puag ncig nws kom lawv nyob ntau qhov chaw ntawm thaj tsam sab hauv ntawm ob lub paj hlwb.

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)
Lub luag haujlwm ntawm cov txheej txheem mastoid thiab txheej txheem styloid yog dab tsi?
Cov txheej txheem styloid nyob rau sab xub ntiag thiab nruab nrab rau cov txheej txheem mastoid, thiab nyob nruab nrab ntawm lawv yog stylomastoid foramen. Cov foramen no tso cai rau cov leeg nqaij ntawm lub ntsej muag lub ntsej muag tawm ntawm pob txha taub hau thiab mus rau sab hauv txhawb cov leeg ntawm lub ntsej muag
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
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
