Peb ceg loj ntawm cov hlab ntsha trigeminal-lub paj hlwb ophthalmic (V1), maxillary paj (V2) thiab mandibular paj (V3) -converge ntawm trigeminal ganglion (tseem hu ua semilunar ganglion lossis gasserian ganglion), nyob hauv Meckel lub qhov tsua thiab muaj cov xovtooj ntawm tes uas nkag los rau hauv lub paj hlwb.
Ib yam li ntawd ib tug yuav nug, peb ceg ntawm lub paj hlwb trigeminal yog dab tsi?
Cov hlab ntsha trigeminal raws li lub npe qhia tau tsim los ntawm peb ceg loj. Lawv yog cov kws kho qhov muag (V1, sensory), maxillary (V2, sensory) thiab lub hauv siab (V3, lub cev muaj zog thiab lub siab) cov ceg ntoo. Lub hauv paus loj hauv lub hauv paus thiab lub hauv paus lub cev muaj zog me me tawm ntawm lub hlwb ntawm nruab nrab sab ntawm pons.
Kuj Paub, dab tsi yog cov ceg ntawm lub ntsej muag paj? Tsib ceg ceg ntawm lub ntsej muag paj hlwb - lub sijhawm ntawm lub cev, zygomatic ua , pob, marginal mandibular , thiab cov ceg ntoo ntawm ncauj tsev menyuam closely muaj kev cuam tshuam nrog lub cev sib luag nrog cov qog ua qog: lawv tawm los ntawm cov qog qog ntshav sab sauv, sab xub ntiag, thiab ciam teb qis.
Raws li txoj cai, koj puas nco qab cov ceg ntawm cov hlab ntsha trigeminal?
Mnemonic
- sawv: zoo dua orbital fissure (ophthalmic faib ntawm trigeminal paj)
- chav: foramen rotundum (maxillary faib ntawm trigeminal paj)
- nkaus xwb: foramen ovale (mandibular faib ntawm trigeminal paj)
Dab tsi yog lub paj hlwb trigeminal tswj?
Cov trigeminal paj hlwb yog qhov loj tshaj ntawm 12 cranial paj hlwb . Nws lub luag haujlwm tseem ceeb yog xa cov ntaub ntawv nkag siab rau ntawm daim tawv nqaij, qhov quav, thiab cov hnoos qeev ntawm lub ntsej muag. Nws kuj tseem txhawb kev txav mus los hauv cov leeg leeg.

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
Vim li cas peb thiaj sau cov ntshav los ntawm cov hlab ntsha thiab tsis yog los ntawm cov hlab ntsha?
Cov leeg yuav tsum tau li qub kom cov ntshav ntws mus rau lub plawv. Theses li qub yog qhov tshwj xeeb hauv ob txhais ceg thiab caj npab. Lawv tawm tsam lub ntiajteb txawj nqus los tiv thaiv cov ntshav rov qab los. Cov hlab ntsha tsis xav tau li qub vim tias lub siab los ntawm lub plawv ua kom cov ntshav ntws los ntawm lawv mus rau ib qho
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
