Ubongo wanu umangolemera thupi lanu, koma umagwiritsa ntchito zoposa 20% zamphamvu zathupi lanu lonse.

Pamodzi ndi kukhala malo oganiza mozama, ubongo wanu umawongoleranso zochita zambiri za thupi lanu mosachita kufuna. Imafotokozera ma gland anu nthawi yotulutsa mahomoni, imayang'anira kupuma kwanu, ndikuwuza mtima wanu kugunda mwachangu.

Medulla oblongata yanu imangopanga 0,5% ya kulemera kwathunthu kwaubongo wanu, koma imagwira gawo lofunikira pakuwongolera zomwe sizingachitike. Popanda gawo lofunikirali laubongo wanu, thupi lanu ndi ubongo wanu sizimatha kulumikizana.

Munkhaniyi, tiwunika komwe medulla oblongata yanu ili ndikuphwanya ntchito zake zambiri.

Kodi medulla oblongata ili kuti?

Medulla oblongata yanu imawoneka ngati chotupa kumapeto kwa ubongo wanu, kapena gawo laubongo wanu lomwe limalumikizana ndi msana wanu. Iyenso ili kutsogolo kwa gawo la ubongo wanu lotchedwa cerebellum.

Cerebellum yanu imawoneka ngati ubongo wawung'ono wolumikizidwa kumbuyo kwa ubongo wanu. M'malo mwake, dzinalo limatanthauzira kuti "ubongo pang'ono" kuchokera ku Latin.

Bowo mu chigaza chanu chomwe chimalola msana wanu kudutsa chimatchedwa foramen magnum yanu. Medulla oblongata yanu ili pafupi mulingo womwewo kapena pang'ono pamwamba pa dzenje.

Pamwamba pa medulla yanu mumakhala pansi pa ventricle yachinayi ya ubongo wanu. Ma ventricles ndi mabowo omwe amadzaza ndi ubongo wamtsempha wamtsempha womwe umathandizira ubongo wanu kukhala ndi michere.

Kodi medulla oblongata amatani?

Ngakhale ndi yaying'ono, medulla oblongata ili ndi maudindo ambiri ofunikira. Ndikofunikira pakufalitsa zambiri pakati pa msana wanu ndi ubongo. Imayang'aniranso machitidwe anu amtima ndi kupuma. Anayi mwa 12 anu amachokera kudera lino.

Ubongo wanu ndi msana wanu zimalumikizana kudzera mumizere ya mitsempha yomwe imadutsa mu medulla yanu yotchedwa timapepala ta msana. Mathirakitiwa akhoza kukhala akukwera (kutumiza zambiri kuubongo wanu) kapena kutsika (pezani zidziwitso ku msana wanu).

Matrakte anu aliwonse amtundu wa msana amakhala ndi mtundu wina wazidziwitso. Mwachitsanzo, thirakiti yanu yotsatira ya spinothalamic imakhala ndi zidziwitso zokhudzana ndi zowawa komanso kutentha.

Gawo lina la medulla yanu litawonongeka, limatha kubweretsa kulephera kutumiza mtundu wina wa uthenga pakati pa thupi lanu ndi ubongo. Mitundu yazidziwitso zomwe zimapezeka ndimapepala amtunduwu ndi monga:

• ululu ndi kutengeka
• kukhudza kosakomoka
• kukhudza bwino
• kudziwika
• lingaliro la kugwedera
• lingaliro la kukakamizidwa
• kuzindikira kwa minofu
• kulinganiza
• kamvekedwe kanyama
• ntchito yamaso

Mtanda wanu kuchokera kumanzere kwa ubongo wanu kumanja kwa msana wanu mu medulla wanu. Mukawononga mbali yakumanzere ya medulla yanu, izi zidzapangitsa kuti magalimoto azitha kumanja. Momwemonso, ngati mbali yakumanja ya medulla yawonongeka, idzakhudza mbali yakumanzere ya thupi lanu.

Kodi chimachitika ndi chiyani ngati medulla oblongata yawonongeka?

Ngati medulla yanu yawonongeka, ubongo wanu ndi msana wanu sizitha kupatsirana chidziwitso kwa wina ndi mnzake.

Kuwonongeka kwa medulla oblongata kumatha kubweretsa ku:

• mavuto opuma
• Kulephera kwa lilime
• kusanza
• kutaya kwa gag, kuyetsemula, kapena kutsokomola
• mavuto kumeza
• kutayika kwa minofu
• mavuto moyenera
• Ma hiccups osalamulirika
• kutaya mphamvu m'miyendo, thunthu, kapena nkhope

Kodi pali matenda ena omwe amakhudza medulla oblongata?

Mavuto osiyanasiyana amatha kukhala ngati medulla yanu itawonongeka chifukwa cha sitiroko, kufooka kwa ubongo, kapena kuvulala kwamutu mwadzidzidzi. Zizindikiro zomwe zimabwera zimadalira gawo lina la medulla yanu yomwe yawonongeka.

Matenda a Parkinson

Matenda a Parkinson ndi matenda omwe amapita patsogolo omwe amakhudza ubongo wanu komanso zamanjenje. Zizindikiro zazikulu ndi izi:

• kunjenjemera
• kuyenda pang'onopang'ono
• kuuma kwa miyendo ndi thunthu
• kusokoneza mavuto

Zomwe zimayambitsa Parkinson sizikudziwika, koma zizindikilo zambiri zimachitika chifukwa cha kuwonongeka kwa ma neuron omwe amapanga neurotransmitter yotchedwa dopamine.

Amakhulupirira kuti kufooka kwa ubongo kumayambira pomwe isanafalikire mbali zina zaubongo. Anthu omwe ali ndi Parkinson nthawi zambiri amakhala ndi vuto la mtima ndi kuwongolera mtima komanso kuthamanga kwa magazi.

Kafukufuku wa 2017, wopangidwa ndi odwala 52 omwe ali ndi matenda a Parkinson, adakhazikitsa ubale woyamba pakati pa zovuta za medulla ndi Parkinson. Anagwiritsa ntchito ukadaulo wa MRI kuti apeze zovuta zam'magawo ena a medulla okhudzana ndi mavuto amtima omwe anthu omwe amakhala ndi Parkinson amakhala nawo.

Matenda a Wallenberg

Matenda a Wallenberg amadziwikanso kuti lateral medullary syndrome. Nthawi zambiri zimachitika chifukwa cha sitiroko pafupi ndi medulla. Zizindikiro zodziwika za matenda a Wallenberg ndi monga:

• kumeza zovuta
• chizungulire
• nseru
• kusanza
• mavuto moyenera
• Ma hiccups osalamulirika
• Kutaya kwa ululu ndi kutentha kwa theka la nkhope
• dzanzi mbali imodzi ya thupi

Matenda a Dejerine

Matenda a Dejerine kapena medial medullary syndrome ndizovuta zomwe zimakhudza anthu ochepera 1% omwe ali ndi zilonda zomwe zimakhudza gawo lakumbuyo kwaubongo wawo. Zizindikiro zake ndi izi:

• kufooka kwa mkono ndi mwendo mbali inayo ya kuwonongeka kwa ubongo
• kufooka kwa lilime mbali yomweyo ya kuwonongeka kwa ubongo
• kutaya chidwi kumbali inayo ya kuwonongeka kwa ubongo
• ziwalo za miyendo mbali inayo ya kuwonongeka kwa ubongo

Matenda a medialary medialary medialary

Matenda a medialary medullary ndizovuta zomwe zimachitika chifukwa cha sitiroko. Gawo limodzi lokha la 1% la anthu omwe ali ndi zikwapu kumbuyo kwa ubongo wawo ndi omwe amakhala ndi vutoli. Zizindikiro zake ndi izi:

• kupuma kulephera
• ziwalo za miyendo yonse inayi
• Kulephera kwa lilime

Matenda a Reinhold

Reinhold syndrome kapena hemimedullary syndrome ndizosowa kwambiri. Pali zochepa zokha m'mabuku azachipatala omwe akwanitsa izi. Zizindikiro zake ndi izi:

• ziwalo
• kutayika kwakumverera mbali imodzi
• kutaya mphamvu kwa minofu mbali imodzi
• Matenda a Horner
• kutayika kwakumverera mbali imodzi ya nkhope
• nseru
• kuvuta kuyankhula
• kusanza

Zotenga zazikulu

Medulla oblongata yanu ili kumapeto kwa ubongo wanu, pomwe tsinde laubongo limalumikizira ubongo ndi msana wanu. Imachita mbali yofunikira pakudutsa mauthenga pakati pa msana wanu ndi ubongo. Ndikofunikanso kuwongolera machitidwe anu amtima ndi kupuma.

Medulla oblongata yanu ikawonongeka, imatha kubweretsa kupuma, kufooka, kapena kutaya chidwi.
