Mitsempha chamawonedwe, matabwa ake ndi ntchito

Mitsempha chamawonedwe wa misempha apadera kwambiri ndi dongosolo akufanana kotekisi ubongo. Nchito ya mitsempha chamawonedwe ali kufala kwa zikhumbo za mitsempha, analandira atadziŵa zikuchitika osiyana kuwala kwa diso kwa malo zithunzi ubongo kotekisi.

Chamawonedwe mitsempha: kapangidwe.

Mitsempha ulusi kwa diso amaphatikizidwa mu umodzi chamawonedwe mitsempha. Amakhala m'madipatimenti zinayi: intraocular, vnutrikanaltsevoy, intraorbital ndi intracranial. The intraocular olekanitsidwa ndi chimbale ndi awiri a za 1.5 mm. Mbali yozungulira ali ndi kutalika kwa pafupifupi 3 cm. The mitsempha chamawonedwe ali kutalika 5-6 mm m'njira fupa ndi 4-17 mm njira intracranial.

mathero Location mitsempha m'madera osiyanasiyana kwa diso wamangidwa pa dongosolo ena. Choncho, pamene tikuyandikira chimbale, ndi mitsempha CHIKWANGWANI wosanjikiza ali ndi makulidwe chachikulu, mitsempha ulusi mu chimbale ndi ndichotse pa kumathandiza kupeza ngodya zabwino bwino, n'kupanga wapadera intraocular chamawonedwe mitsempha.

Mitsempha chamawonedwe akuyamba ku litayamba, ndipo ikutha mu chiasm lapansi. Mitsempha chamawonedwe mu wamkulu ali kutalika mamilimita 35 55. Iwo ali ndi meninges atatu: molimba, zofewa ndi arachnoid. Danga pakati zipolopolo ladzala ndi madzi wapadera ndi zovuta mankhwala zikuchokera.

ulusi chamawonedwe m'maso onse zili M'mimbamo cranial, amene olumikizidwa ku sella. Kuziika pamodzi amatchedwa chiasm. Ndi pang'ono intersect CHIKWANGWANI chamawonedwe. Intersecting ulusi imvera amene amachokera ku mbali mkati mwa diso. polumikizana izi nzofunikira kwambiri kuti matenda olondola a matenda ena. Atawoloka timapepala chamawonedwe anapanga amene m'munsi mwa ubongo tsinde akudutsa mozungulira ndi mapeto pa crankshaft matupi quadrigemina kutsogolo ndi dera kumbuyo kwa thalamus lapansi. matupi Geniculate ndi zofunika kwambiri kufala kwa zikhumbo kwa kotekisi zithunzi. Anthu ulusi umene kutsirizitsa mu thalamus ndi atengedwere reflex lamulo la bongo choipidwa ndi somatic. A kutsogolo matupi quadrigeminal ntchito kulanda wa ana bongo. ulusi chamawonedwe pochitika kwa mtima wa oculomotor mitsempha, monga gawo limene iwo kulowa diso, chifukwa mu minofu ya Iris lapansi.

Njira khalidwe pathological, omwe amatuluka mu mitsempha chamawonedwe, ali paubwenzi ndi matabwa ake. Chifukwa cha kuchuluka kwa capillaries kuti zili partitions ndi anazungulira mitsempha chamawonedwe, komanso kuchuluka kudziwa poizoni, zikhalidwe za zotsatira poizoni pa misempha chamawonedwe, ndi matenda opatsirana. Ndi kuwonjezeka mu kuthamanga intraocular mfundo pachiopsezo amakhala chimbale cha, umene mu khungu ndi mbamuikha anapanga fossa. Mkulu intracranial kuthamanga lofotokozabe outflow madzi mu yapakati-danga, chifukwa mu psinjika mitsempha ndi kutupa ali m'bukuli mankhwala interstitial.

The CD amakhalanso zimawononga kungasokoneze kusintha hydrodynamic ndi hemodynamic chopatsa kuchepa kuthamanga intraocular. kusintha kulikonse mu mitsempha chamawonedwe nthawi zonse zinthuzo kukanika masomphenya zotumphukira kapena chapakati, pamene pali kuwonongeka kwa madzulo masomphenya ndi kusiyana mtundu. Matenda okhudzana ndi mitsempha chamawonedwe, ndi osachiritsika, kutupa kapena matupi awo sagwirizana m'chilengedwe. Nthawi zina pali zotupa ndi kuvutika mu chitukuko ndi kapangidwe ka mitsempha chamawonedwe.
