Qhov sib txawv tseem ceeb ntawm exencephaly thiab anencephaly yog exencephaly yog ib qho mob cephalic uas lub hlwb cov ntaub so ntswg nyob sab nraum lub pob txha taub hau vim tsis muaj cov kab noj hniav cranial thiab tawv taub hau. Lub caij no, anencephaly yog ib qho mob cephalic uas tshwm sim los ntawm qhov tsis muaj ib feem ntawm lub hlwb, pob txha taub hau thiab tawv taub hau vim qhov tsis ua haujlwm ntawm rostral neuropore kaw.
Cov kab mob Congenital tshwm sim vim qhov tsis xws ntawm neural uas tshwm sim thaum cev xeeb tub. Lawv ua rau muaj kev tuag ntau, ua rau tus mob tuag taus. Exencephaly thiab anencephaly yog ob yam kab mob hauv lub cev thiab cov kab mob cephalic pom hauv cov me nyuam mos. Hauv exencephaly, lub hlwb nyob sab nraum lub pob txha taub hau. Hauv anencephaly, ib feem tseem ceeb ntawm lub hlwb, pob txha taub hau thiab tawv taub hau tsis tuaj. Exencephaly yog suav tias yog ib qho embryological precursor ntawm anencephaly. Txawm li cas los xij, exencephaly yog ib qho mob tsawg heev piv rau anencephaly.
Exencephaly yog dab tsi?
Exencephaly yog ib yam mob uas pom nyob rau hauv lub embryo thaum ntxov. Nws yog ib hom kab mob cephalic uas lub hlwb nyob sab nraum lub pob txha taub hau. Nws tshwm sim vim tsis muaj cov kab noj hniav cranial thiab tawv taub hau. Yog li ntawd, ib tug loj npaum li cas ntawm lub hlwb cov ntaub so ntswg yog pom protruding sab nraum. Tsis tas li ntawd, qhov teeb meem no yog tus cwj pwm los ntawm cov pob qhov muag pom. Thaum exencephaly tshwm sim, nws ua rau maj mam degeneration ntawm cov ntaub so ntswg ntawm lub hlwb vim raug cov kua amniotic ua ke nrog cov neeg kho tshuab raug mob.
Daim duab 01: Exencephaly
Exencephaly yog ib yam kab mob tsawg heev. Nws yog ib qho nyuaj heev los nrhiav tus menyuam mos pob txha nrog exencephaly vim feem ntau exencephalics tseem yug los.
Anencephaly yog dab tsi?
Anencephaly yog hais txog kev txhim kho tsis tiav ntawm lub hlwb, pob txha taub hau thiab tawv taub hau. Lub neural tube defect tshwm sim thaum lub sij hawm embryonic txoj kev loj hlob. Lawv tshwm sim thaum lub sij hawm peb thiab plaub lub lis piam ntawm cev xeeb tub. Thaum lub sij hawm anencephaly, lub neural raj tsis kaw kom zoo. Qhov no ua rau muaj kev loj hlob tsis tiav ntawm lub hlwb lossis tsis ua haujlwm ntawm lub hlwb. Anencephaly yog qhov teeb meem ntawm lub paj hlwb uas pom hauv cov me nyuam mos.
Daim duab 02: Anencephaly
Anencephaly yog ib yam kab mob caj ces. Nyob rau hauv qhov tseeb, nws yog ib tug multifactorial mob qhov twg ntau yam noob caj noob ces thiab ib puag ncig yam muaj feem xyuam rau qhov pib. Nws kuj tseem tuaj yeem tshwm sim vim yog chromosomal aberration (trisomy 18). Muaj ob peb yam ntxwv txuam nrog anencephaly. Lawv yog qhov tsis muaj nyob rau hauv pem hauv ntej ntawm lub hlwb (forebrain), tsis muaj cerebral hemispheres thiab lub cerebellum, raug lub hlwb cov ntaub so ntswg uas tsis muaj lub pob txha taub hau, impaired nco qab thiab siab tuag tus nqi.
Dab tsi zoo sib xws ntawm Exencephaly thiab Anencephaly?
- Exencephaly thiab anencephaly yog cov kab mob cephalic tshwm sim vim qhov tsis zoo ntawm lub raj neural.
- Ob qho kev mob tshwm sim muaj feem xyuam rau lub hauv nruab nrab lub paj hlwb thiab lub taub hau.
- Qhov tseeb, ob hom kev mob tshwm sim vim qhov tsis zoo ntawm cov hlab ntsha neural.
- Cov kab mob no tshwm sim thaum lub sij hawm kev loj hlob ntawm embryonic.
- Ntxiv mus, ob qho tib si no mob tuag taus thiab kho tsis tau.
Qhov txawv ntawm Exencephaly thiab Anencephaly yog dab tsi?
Exencephaly yog ib qho mob cephalic uas muaj ntau cov ntaub so ntswg ntawm lub hlwb protrudes tawm ntawm lub cranial kab noj hniav thiab tsis npog los ntawm daim tawv nqaij thaum anencephaly yog tag nrho cov tsis muaj nyob rau hauv lub loj feem ntawm lub hlwb, pob txha taub hau thiab tawv taub hau. tsis ua hauj lwm ntawm rostral neuropore kaw. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm exencephaly thiab anencephaly. Exencephaly tsis tshua muaj tshwm sim nyob rau hauv cov me nyuam mos thaum anencephaly yog feem ntau cov neural tube disorder pom nyob rau hauv cov me nyuam mos.
Hauv qab infographic qhia qhov txawv ntawm exencephaly thiab anencephaly.
Summary – Exencephaly vs Anencephaly
Anencephaly thiab exencephaly yog ob qho tib si hauv nruab nrab lub paj hlwb txawv txav. Exencephaly yog tus kab mob cephalic uas tshwm sim los ntawm qhov muaj cov ntaub so ntswg ntawm lub hlwb sab nraum lub pob txha taub hau. Anencephaly yog tus kab mob cephalic uas tshwm sim los ntawm qhov tsis muaj qhov loj ntawm lub hlwb, pob txha taub hau thiab tawv taub hau. Nws tshwm sim vim qhov ua tsis tiav ntawm rostral neuropore kaw thaum yug los. Exencephaly yog ib yam mob tsawg heev thiab feem ntau tseem yug los. Txawm li cas los xij, anencephaly yog qhov teeb meem ntawm lub paj hlwb uas pom hauv cov me nyuam mos. Qhov tseem ceeb tshaj plaws, ob qho tib si ntawm cov kab mob cephalic no ua rau tuag taus thiab tsis tuaj yeem kho. Yog li, qhov no qhia txog qhov sib txawv ntawm exencephaly thiab anencephaly.
