The corpus callosum chimiro chiri mukati meuropi uye chinobatanidza maviri ekuruboshwe nekurudyi hemispheres.

nzvimbo. Iyo corpus callosum ndiyo huru junction pakati pekuruboshwe nekurudyi hemispheres yehuropi (1). Inowanikwa pakati uye yakananga kuzasi kwehemispheres mbiri. Iyo yepamusoro yepamusoro ye corpus callosum saka inosangana nehemispheres.

mamiriro. Arch-shaped, iyo corpus callosum isumbu rinoumbwa neavhareji ye200 miriyoni nerve fibers. Mafibisi aya anokura kuburikidza nechinhu chichena chezvikamu zvakasiyana-siyana kana nzvimbo dzehemispheres.

Iyo corpus callosum inoumbwa nenzvimbo ina dzakasiyana, dzinoti, kubva kumberi kuenda kumashure (1):

• Rostrum, kana muromo, unobatanidza kuruboshwe nekurudyi kumberi kwaro;
• Ibvi, kubatanidza kuruboshwe uye rworudyi parietal lobes;
• Hunde, inobatanidza kuruboshwe uye kurudyi temporal lobes;
• Uye selenium, inobatanidza kuruboshwe uye kurudyi occipital lobes.

Vascularization. Iyo corpus callosum inopihwa neaviri anterior cerebral arteries, kunze kweiyo splenium. Iyo yekupedzisira ine chikamu chevascularized nematavi e-posterior cerebral artery (1).

Kukurukurirana pakati pemahemispheres maviri. Iyo corpus callosum inoita basa guru mukufambiswa kwemashoko pakati pekuruboshwe nekurudyi hemispheres yeuropi. Kukurukurirana uku kunobvumira kurongeka kwemahemispheres maviri, kududzirwa kwemashoko uye chiito maererano (1).

Chikamu chakakosha chepakati tsinga system, iyo corpus callosum inogona kunge iri nzvimbo yeakawanda pathologies, izvo zvinokonzeresa zvingave zvekuzvimba, kutapukira, bundu, vascular, traumatic mavambo kana angave akabatana nekusagadzikana.

Agenesis ye corpus callosum. Iyo corpus callosum inogona kunge iri saiti yekukanganisa, imwe yeanowanzo gara ari agenesis.

Head trauma. Zvinoenderana nekuvhunduka kudehenya iro rinogona kukonzera kukuvara kwehuropi. (2) Maronda aya anogona kuva concussions, kureva reversible maronda, kana contusions, maronda asingachinjiki (3).

Stroke. Cerebrovascular accident, kana sitiroko, inoratidzwa nekuvharwa, zvakadai sekuumbwa kweropa rekuvhara kana kuputika kwemudziyo weropa muuropi. (4) Iyi pathology inogona kukanganisa mabasa ecorpus callosum.

Mamota muuropi. Benign kana mamota akaipa anogona kukura mu corpus callosum. (5)

Multiple sclerosis. Iyi pathology chirwere che autoimmune chepakati tsinga system. Iwo immune system inorwisa myelin, sheath yakatenderedza nerve fibers, zvichikonzera kuzvimba. (6)

Zvinodhaka zvinodhaka. Zvichienderana nehutachiona hwakawanikwa, mamwe marapirwo anogona kupihwa akadai seanorwisa-kupisa mishonga.

Thrombolyse. Inoshandiswa panguva yekurohwa, kurapwa uku kunosanganisira kupwanya iyo thrombi, kana kuwanda kweropa, nerubatsiro rwemishonga. (4)

Kuvhiya kurapa. Zvichienderana nerudzi rwehutachiona hwakaonekwa, kuvhiya kunogona kuitwa.

Chemotherapy, radiotherapy. Zvichienderana nedanho rebundu, marapirwo aya anogona kuitwa.

Kuongorora kwepanyama. Kutanga, kuongororwa kwekiriniki kunoitwa kuitira kucherechedza uye kuongorora zviratidzo zvinoonekwa nemurwere.

Medical imaging kuongorora. Kuti uongorore kukanganisa kweuropi, cerebral uye spinal CT scan kana cerebral MRI inogona kunyanya kuitwa.

Biopsy. Ongororo iyi ine sampuli yemaseru.

Lumbar puncture. Iyi bvunzo inobvumira cerebrospinal fluid kuti iongororwe.

Basa re corpus callosum rakazarurwa mumakore makumi mashanu nekuda kwebasa raRonald Myers naRoger Sperry kuCalifornia Institute of Technology (50). Zvidzidzo zvavo pachikamu che corpus callosum mumakatsi zvakaratidza kuti hapana mhedzisiro pamaitiro apo kudzidza faculty uye maonero aiita kunge akachinjwa (7).
