Lub paj hlwb muaj peb yam tseem ceeb: lub paj hlwb, cerebellum thiab hlwb . Cerebrum: yog qhov loj tshaj plaws ntawm lub hlwb thiab yog tsim los ntawm sab xis thiab sab laug hemispheres. Nws ua haujlwm zoo dua qub xws li txhais lus kov, pom kev thiab hnov lus, nrog rau kev hais lus, kev xav, kev xav, kev kawm, thiab kev tswj kom zoo.
Zoo ib yam tuaj yeem nug, 4 feem ntawm lub hlwb yog dab tsi thiab lawv ua haujlwm li cas?
Txhua hemisphere muaj plaub seem, hu ua lobes: frontal, parietal, temporal thiab occipital. Txhua lub lobe tswj tshwj xeeb muaj nuj nqi . Piv txwv li, lub hauv ntej lub qhov muag tswj tus kheej, kev txiav txim siab thiab kev xav, thaum lub lobe sab hauv tswj, nco, hais lus, thiab hnov ntxhiab tsw.
Ib yam nkaus, 3 feem ntawm lub hlwb yog dab tsi thiab lawv txoj haujlwm yog dab tsi? Lub paj hlwb muaj peb ntu tseem ceeb:
- Lub paj hlwb nyob puv koj pob txha taub hau. Nws koom nrog hauv kev nco qab, daws teeb meem, xav, thiab xav.
- Lub cerebellum zaum tom qab koj lub taub hau, hauv qab lub paj hlwb. Nws tswj kev sib koom tes thiab sib npaug.
- Lub paj hlwb nyob hauv qab koj lub paj hlwb ua ntej koj lub paj hlwb.
Cov lus nug tseem yog, dab tsi yog 7 ntu ntawm lub hlwb?
Cov cheeb tsam no yog: Lob Occipital, Lobe Temporal, Lobe Parietal, Lobe Frontal. Cerebral cortex, Cerebellum, Hypothalamus, Thalamus, Pituitary gland, Pineal gland, Amygdala, Hippocampas thiab Mid- lub hlwb.
Lub hauv paus ntawm koj lub hlwb hu li cas?
Lub cerebellum yog nyob ntawm puag thiab sab nraum qab ntawm lub hlwb . Lub cerebellum yog lub luag haujlwm rau kev sib koom tes thiab sib npaug. Lub occipital lobes muaj cov hlwb pom kev ua haujlwm. Cov lub hlwb yog nyob ib puag ncig ntawm cov ntaub so ntswg hu ua cov meninges.

Lub sijhawm rau cov ntaub so ntswg dawb nyob ib ncig ntawm lub qhov muag thiab tsim lub hauv paus txheej txheem ntawm lub ntiaj teb yog dab tsi?
Qhov muag. Cov ntaub so ntswg dawb nyob ib ncig ntawm lub qhov muag thiab ua lub hauv paus tseem ceeb ntawm lub ntiaj teb yog. iris, lub cev ciliary, choroid. Cov qauv ntawm cov kab mob uveal, lossis uvea, yog. dej lom zem
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
Cov txheej txheem ntawm Seldinger txheej txheem yog dab tsi?
Cov txheej txheem ntawm Seldinger Cov Txheej Txheem Kev Txhaj Tshuaj. Ntxuav thiab npaj qhov chaw xav tau. Insertion ntawm Guidewire. Tshem tawm koob. Qhov chaw txhaj tshuaj tau nthuav dav los ntawm kev siv cov hniav lossis cov zom zaws. Catheter tau muab tso rau. Qhov tso zaum kawg - rub daim ntawv qhia 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
