Cov olfactory paj hlwb (I), hla dhau perforations nyob rau hauv lub cribriform phaj ib feem ntawm cov pob txha ethmoid. Cov paj hlwb fibers xaus nyob rau hauv lub Upper nasal kab noj hniav. Lub optic paj hlwb (II) hla dhau lub optic cov lus qhia nyob rau hauv cov pob txha sphenoid thaum nws mus rau qhov muag.
Tsis tas li ntawd, cov hlab ntsha ntawm cov hlab ntsha twg dhau los ntawm lub foramen?
Foramen Rotundum. Lub foramen rotundum nyob ntawm lub hauv paus ntawm lub tis ntau dua ntawm sphenoid, qis dua rau qhov zoo tshaj plaws orbital fissure. Nws muab kev sib txuas ntawm nruab nrab cranial fossa thiab pterygopalatine fossa. Cov maxillary paj hlwb (txog ntawm cov hlab ntsha trigeminal, CN V) dhau los ntawm cov lus qhia no.
Ib yam li ntawd, puas cov hlab ntsha olfactory dhau los ntawm thalamus? Teb thiab Piav Qhia: Qhov kev nkag siab ntawd ua tsis mus dhau lub thalamus yog tsw. Cov ntxhiab tsw tau kuaj pom los ntawm chemoreceptors hauv cov olfactory epithelium nyob rau hauv lub qhov ntswg.
Tsis tas li ntawd, cov hlab ntsha olfactory hla qhov twg?
Cov olfactory paj hlwb yog thawj cranial paj hlwb thiab xa cov ntaub ntawv tshwj xeeb ntawm kev hnov qab txog kev hnov tsw. Nws yog qhov luv tshaj ntawm lub cranial paj hlwb thiab hla los ntawm nws receptors nyob rau hauv lub qhov ntswg mucosa mus rau forebrain. Nws nkag mus rau pob txha taub hau dhau phaj cribriform ntawm cov pob txha ethmoid.
Dab tsi dhau los ntawm qhov muag foramen?
Cov optic cov ntaub ntawv , qhov qhib dhau koj e qhov muag cov hlab ntsha rov qab mus rau hauv lub hlwb thiab cov hlab ntsha loj ophthalmic nkag mus rau hauv qhov chaw, yog nyob ntawm qhov ntswg ntawm lub apex; lub superior orbital fissure yog lub qhov loj dhau qhov twg hla cov hlab ntsha loj thiab cov hlab ntsha.…

Dab tsi yog qhov txawv ntawm cov hlab ntsha thiab cov hlab ntsha capillaries?
Piav qhia: Cov hlab ntshav nqa ntshav nyob hauv siab los ntawm lub plawv mus rau cov kabmob thiab cov nqaij. Lawv cov phab ntsa feem ntau yog tuab dua li cov leeg. Capillaries yog qhov sib txuas ntawm cov hlab ntsha thiab cov leeg thiab me me heev, Cov ntaub so ntswg qee zaum pom tawm thiab rov nco qab los ntawm cov qog ntshav thiab rov qab los rau cov leeg ntshav
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
Dab tsi yog cov hlab ntsha thiab cov hlab ntsha capillaries?
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
Dab tsi yog cov hlab ntsha tseem ceeb ntawm cov hlab ntsha?
Cov hlab ntsha, cov hlab ntsha thiab lymphatic system yog cov hlab ntsha tseem ceeb hauv lub cev circulating system. parasympathetic - lub luag haujlwm rau vasoconstriction
