Cov hlab ntsha . Cov leeg ntawm nplaig yog muab los ntawm cov lus cov leeg , a ceg ntawm sab nrauv carotid cov leeg . Nws ceg tawm los ntawm nws hauv lub caj dab ntawm qib siab dua ntawm cov pob txha hyoid.
Kuj paub, koj tus nplaig puas muaj cov leeg ntshav?
Cov nplaig tau txais nws cov ntshav txaus los ntawm cov lus cov leeg , ib ceg ntawm sab nraud carotid cov leeg . Cov hlab ntsha lingual ntws mus rau sab hauv jugular leeg. Hauv pem teb ntawm lub qhov ncauj kuj tau txais nws cov ntshav los ntawm cov lus cov leeg.
Ib yam li ntawd, cov hlab ntsha sublingual nyob qhov twg? Cov Sublingual Artery tshwm sim ntawm cov npoo npoo av ntawm hyoglossus, thiab khiav mus tom ntej ntawm genioglossus thiab mylohyoid cov leeg mus rau sublingual qog. Nws muab cov qog thiab muab ceg rau mylohyoideus thiab cov leeg nyob sib ze, thiab mus rau cov hnoos qeev ntawm lub qhov ncauj thiab cov pos hniav.
Ib yam nkaus, tib neeg nug, koj puas muaj cov leeg tseem ceeb hauv koj tus nplaig?
Cov leeg ntawm tus nplaig . (Lus Askiv leeg sau rau ntawm sab laug.) Cov lus leeg pib rau cov dorsum, sab, thiab hauv qab nto ntawm tus nplaig , thiab, hla rov qab nrog cov chav kawm ntawm lus cov leeg , kawg in cov internal jugular leeg.
Muaj pes tsawg lub paj hlwb nyob hauv koj tus nplaig?
Zuag qhia tag nrho, cov XII paj hlwb hauv cov neeg laus muab kwv yees li 50-60 tus thawj paj hlwb ceg raws nws tag nrho ntev nyob rau hauv tus nplaig.

Cov hlab ntsha hlab ntsha thiab cov hlab ntshav muaj dab tsi?
Cov hlab ntsha nqa ntshav tawm ntawm lub plawv; Lub ntsiab hlab ntsha yog aorta. Capillaries nqa ntshav tawm ntawm lub cev thiab pauv cov as-ham, pov tseg, thiab oxygen nrog cov ntaub so ntswg ntawm qib cellular. Cov leeg ntshav yog cov hlab ntshav uas coj cov ntshav rov qab los rau hauv lub plawv thiab tso ntshav tawm ntawm cov kabmob thiab cov ceg
Puas yog Neuroglia tsim cov hlab ntsha hauv cov hlab ntsha hauv nruab nrab cov hlab ntsha?
Muaj plaub hom neuroglia pom nyob hauv nruab nrab lub paj hlwb: Astrocytes - tswj cov ntshav lub hlwb teeb meem thiab khaws cov tshuaj ib puag ncig los ntawm kev siv cov ions rov qab thiab cov tshuaj xa xov mus rau lub cev. Oligodendrocytes - myelinate axons nyob rau hauv lub hauv nruab nrab lub paj hlwb thiab muab tag nrho cov txheej txheem txheej txheem
Puas yog cov hlab ntsha uas muaj oxygenated ntshav lossis cov hlab ntsha?
Cov hlab ntsha tau pom tias yog nqa cov ntshav oxygenated mus rau cov ntaub so ntswg, thaum cov leeg nqa cov ntshav deoxygenated rov qab mus rau lub plawv. Txawm li cas los xij, hauv txoj hlab ntsws, cov hlab ntsha nqa cov ntshav deoxygenated los ntawm lub plawv mus rau lub ntsws, thiab cov hlab ntshav rov qab ntshav los ntawm lub ntsws mus rau lub plawv
Koj tuaj yeem qhia qhov sib txawv ntawm cov hlab ntsha thiab cov hlab ntsha li cas?
Cov hlab ntshav yog cov hlab ntshav ua lub luag haujlwm nqa cov pa oxygen ntau ntawm lub plawv mus rau lub cev.Cov leeg ntshav yog cov hlab ntshav uas nqa cov ntshav qis inoxygen los ntawm lub cev rov mus rau lub plawv forreoxygenation
Cov hlab ntsha hauv lub ntsws txawv li cas ntawm cov hlab ntsha hauv nruab nrog cev?
Cov hlab ntsha. Cov hlab ntsha hauv lub ntsws nqa cov ntshav oxygen tsawg los ntawm txoj hlab ntshav ntawm lub plawv mus rau lub ntsws. Cov hlab ntsha hauv lub cev thauj cov ntshav oxygenated los ntawm sab laug ventricle ntawm lub plawv mus rau tag nrho lub cev. Cov leeg
