The corpus callosum ndi kamangidwe kamene kamakhala mkati mwa ubongo ndikugwirizanitsa ma hemispheres awiri kumanzere ndi kumanja.

malo. corpus callosum ndiye mphambano yayikulu pakati pa magawo amanzere ndi kumanja a ubongo (1). Ili pakatikati ndi kumunsi kwa ma hemispheres awiri. Kumtunda kwa corpus callosum motero kumakhudzana ndi ma hemispheres.

kapangidwe. corpus callosum ndi mtolo wopangidwa ndi pafupifupi 200 miliyoni mitsempha ya mitsempha. Ulusi umenewu umakula kupyolera mu zinthu zoyera za lobes kapena madera osiyanasiyana a hemispheres.

corpus callosum imapangidwa ndi madera anayi osiyana, omwe ndi, kuchokera kutsogolo kupita kumbuyo (1):

• Rostrum, kapena mlomo, wolumikiza mbali zakumanzere ndi zakumanja zakutsogolo;
• Bondo, kulumikiza kumanzere ndi kumanja kwa parietal lobes;
• Thunthu, kulumikiza kumanzere ndi kumanja lobes zosakhalitsa;
• Ndipo selenium, kulumikiza kumanzere ndi kumanja kwa occipital lobes.

Kutulutsa minofu. The corpus callosum imaperekedwa ndi mitsempha iwiri yapambuyo yaubongo, kupatulapo splenium. Chomalizacho chimapangidwa ndi nthambi za mtsempha wakumbuyo waubongo (1).

Kulumikizana pakati pa ma hemispheres awiri. The corpus callosum imatenga gawo lalikulu pakusamutsa chidziwitso pakati pa ma hemispheres akumanzere ndi kumanja a ubongo. Kuyankhulana uku kumapangitsa kugwirizanitsa kwa ma hemispheres awiri, kutanthauzira kwa chidziwitso ndi zomwe zimachitika molingana (1).

Mbali yofunika ya chapakati mantha dongosolo corpus callosum akhoza kukhala malo ambiri pathologies, zomwe zimayambitsa zotupa, matenda, chotupa, mtima, zoopsa chiyambi kapena mwina chogwirizana ndi zofooka.

Agenesis wa corpus callosum. The corpus callosum ikhoza kukhala malo a zolakwika, chimodzi mwazomwe zimachitika pafupipafupi ndi agenesis.

Kupwetekedwa mutu. Zimafanana ndi kugwedezeka kwa chigaza komwe kungayambitse ubongo. (2) Zotupazi zimatha kukhala zosokoneza, mwachitsanzo, zotupa zosinthika, kapena zotupa, zotupa zosasinthika (3).

Sitiroko. Ngozi ya cerebrovascular, kapena stroke, imawonetsedwa ndi kutsekeka, monga kupangika kwa magazi kapena kupasuka kwa chotengera cha magazi mu ubongo. (4) Matendawa amatha kukhudza ntchito za corpus callosum.

Zotupa muubongo. Zotupa zabwino kapena zoyipa zimatha kukhala mu corpus callosum. (5)

Matenda angapo ofoola ziwalo. Kudwala Izi ndi autoimmune matenda a chapakati mantha dongosolo. Chitetezo cha mthupi chimagwiritsa ntchito myelin, mchimake womwe umazungulira ulusi wamitsempha, womwe umayambitsa zotupa. (6)

Mankhwala osokoneza bongo. Kutengera matenda omwe amapezeka, mankhwala ena amatha kuperekedwa ngati mankhwala oletsa kutupa.

Kuphulika. Amagwiritsidwa ntchito pakamenyedwa, chithandizo ichi chimakhala kuthyola thrombi, kapena kuundana kwamagazi, mothandizidwa ndi mankhwala. (4)

Chithandizo cha opaleshoni. Kutengera mtundu wamatenda omwe amapezeka, opaleshoni imatha kuchitidwa.

Chemotherapy, mankhwala a radiotherapy. Kutengera gawo la chotupacho, mankhwalawa atha kuchitidwa.

Kuyesedwa kwakuthupi. Choyamba, kuyezetsa kuchipatala kumachitika kuti muwone ndikuwunika zomwe wodwala akuwona.

Kuyeza kujambula kwachipatala. Pofuna kuyesa kuwonongeka kwa ubongo, CT scan ya ubongo ndi msana kapena MRI ya ubongo ikhoza kuchitidwa makamaka.

Biopsy. Kuwunikaku kumakhala ndi zitsanzo zama cell.

Kuphulika kwa lumbar. Mayesowa amalola kuti cerebrospinal fluid iwunikidwe.

Ntchito ya corpus callosum idavumbulutsidwa mu 50s chifukwa cha ntchito ya Ronald Myers ndi Roger Sperry ku California Institute of Technology (7). Maphunziro awo pa gawo la corpus callosum mwa amphaka adawonetsa kuti palibe chokhudza khalidwe pomwe luso la kuphunzira ndi kuzindikira zikuwoneka kuti zasinthidwa (1).
