Matenda a mitsempha trigeminal ndi nthambi zake

Misempha ndi maziko ya ubongo. Ambiri mwa iwo ndi cranial, kuti likutuluka ubongo. wotereyo ndi mitsempha trigeminal. ndi thunthu la mitsempha trigeminal chiyani?

Ndi chiyani icho?

Trigeminal mitsempha kapangidwe ndi mitsempha ya mtundu mitundu yosiyanasiyana. 5 amatanthauza awiri misempha cranial.

Pamafunikanso tcheru (afferent centripetal) ndi galimoto (centrifugal) ulusi, umene pa zikhumbo mitsempha zimafalitsidwa onse kuchokera pamwamba (ululu ndi kutentha) ndiponso (proprioceptive) maselo. The zosagwiritsa galimoto innervation ikuchitika pakati zomwe innervates minofu masticatory makamaka. Kodi kwenikweni ndi thunthu la mitsempha trigeminal ndi kutanthauzira kwa nthambi zake?

Mitsempha masamba ubongo m'dera la mlatho. Potuluka ubongo, ambiri a iwo zikuchitika pa piramidi wa fupa mwakanthawi. Pamwamba pali kusiyana mu nthambi zitatu za mitsempha: yozungulira (r.ophthalmicus), maxillary (r.maxillaris) ndi mandibular (r.mandibularis).

mitsempha imeneyi ndi yofunika kwa Madokotala aubongo kuyambira innervates lonse nkhope m'deralo. Nthawi zambiri anati kugonja kwake pa supercooling, zoopsa nkhope dera, matenda a minofu ndi mafupa dongosolo.

Kodi thunthu la mitsempha trigeminal ndi nthambi zake?

yozungulira mitsempha

Nthambi yoyamba ya mitsempha trigeminal ndi mitsempha kapena yozungulira nervus ophthalmicus.

Ziri nthambi thinnest anakafika ku mitsempha trigeminal. Iye anachita makamaka ntchito ya phwando. Innervate khungu la pamphumi, mbali zina za dera kanthawi ndi parietal, ndi chivindikiro pamwamba, kumbuyo kwa mphuno, sinuses, mafupa ena nkhope ndi mucosa pang'ono m'mphuno.

Kapangidwe ka mitsempha ndizo za makumi atatu mitolo ochepa ulusi mitsempha. Mitsempha akulowa zitsulo diso pa mpanda kunja kwa nkusani yozungulira, amene akutumiza nthambi chipika ndi abducens. Mu chapamwamba yozungulira clippings mitsempha anasiyanitsidwa mu atatu ang'onoang'ono ndi woonda mtanda - lacrimal, mazunzo ndi misempha ciliary.

Close kutanthauzira kwa mwana wa m'diso la nthawi zambiri kumayambitsa kugonjetsedwa awo chifukwa cha kuvulala kapena zitsulo diso supraorbital dera.

Ciliary mitsempha, nayenso imagwiritsidwa ciliary ganglion, yomwe ili m'malire a mkati ndi pakati wachitatu wa mitsempha chamawonedwe. Amakhala wa mathero parasympathetic mitsempha nawo innervation wa zopangitsa diso, ndi malo periorbital.

maxillary mitsempha

Nthambi zina za mitsempha trigeminal ndi maxillary kapena nervus maxillaris.

Iye akuchoka M'mimbamo cranial mwa foramen ovale. Kwa izo, iye agwa mu pterygopalatine-Palatine fossa. Kudutsa mmenemo mu mitsempha infraorbital chimafikira mwa dzenje m'munsi yozungulira. Atayendetsa therethrough, mitsempha akuthamanga mu njira yomweyo pa khoma pansi kanjira lapansi. Pa nkhope akutuluka mwa dzenje m'munsi yozungulira komwe linagawanika mu nthambi zing'onozing'ono. Iwo kupanga pawiri ndi nthambi ya mitsempha nkhope ndi innervate khungu kwa chikope m'munsi, chapamwamba mlomo ndi mbali pamwamba pa nkhope. Komanso, ndi maxillary mitsempha nthambi achoka monga zygomatic mitsempha alveolar chapamwamba nthambi kupanga interlacement padziko mano ndi nthambi ganglionic kulumikiza mitsempha maxillary ndi pterygopalatine ganglion-Palatine.

Kugonjetsedwa kwa mitsempha zimawonedwa mu kuvulala chachikulu maso, neuritis, ntchito pa mano ndi sinuses.

mandibular mitsempha

Lachitatu ndi ovuta kwambiri nthambi ya mitsempha trigeminal ndi mandibular kapena nervus mandibularis. Mu kapangidwe kake iwo ali, kupatula nthambi tcheru, lonse la galimoto muzu wa mitsempha trigeminal chochokera galimoto phata, phata motorius, kwa minofu ya chibwano m'munsi. Chifukwa cha dongosolo lino amapereka minofu deta ndi khungu okuta iwo. Mitsempha lotulukira chigaza mwa foramen ovale (chowulungika zenera kapena kutsegula) kenako m'magulu awiri a nthambi:

• nthambi minofu kupita minofu masseter - minofu pterygoid, ndi kanthawi; innervated komanso musculus digastricus.
• Nthambi ali tcheru kwa mucosa buccal, komanso pansi M'mimbamo m'kamwa. Mbali ya nthambi innervate deta ndi chinenero. Yaikulu komanso yaitali nthambi mandibular mitsempha - alveolny m'munsi (magwero ena - alveolar) mitsempha umadutsa ndi foramen maganizo ndi mtsempha wamagazi homonymous ndipo zipita m'munsi nsagwada njira aumbike kumene m'munsi alveolar plexus.

Tikhoza kuganiza kuti ndi nthambi ya mitsempha trigeminal akupitiriza. Kaswili chithunzi cha mitsempha (loukitsa) ndi katundu wake (wosanganiza mitsempha CHIKWANGWANI) amati izi osachiritsika nthambi. Ngakhale kuti ndipamene wosakoma alveolar mitsempha plexus, malo litamalizidwa anganene kuti ndi khomo la ngalande mandibular.

Njira ya ulusi mitsempha

ndi thunthu la mitsempha trigeminal (kapangidwe ndi patsogolo nthambi zake) chiyani?

Kapangidwe ndi yofanana ndi ya mitsempha trigeminal kuti aliyense wa msana misempha. Mitsempha trigeminal ndi lalikulu wapadera wagawo - ndi trigeminal ganglion. mapangidwe ili pakati cranial fossa. Kumbali zonse wazunguliridwa ndi mapepala Dura Mater. Mfundo ali dendrites kuti apange atatu nthambi zikuluzikulu wamkulu wa mitsempha trigeminal. Tcheru mitsempha muzu likulowerera mwa mwendo pakati cerebellum, kumene yotseka pa mtima atatu a ubongo - kumtunda ndi pakati, omwe lili manyuroni yeniyeni imalandira. Injini mbali ya mitsempha akuyamba ku galimoto phata - phata motorius.

Zikomo kuti dongosolo limeneli, mitsempha akhoza poyera ndi a ubongo ndi minofu yoyandikana ndi choncho ndi chidwi Madokotala aubongo.

Matenda a mitsempha trigeminal

Kodi njira zimakhudza mphamvu zinchito za maphunziro ndi njira imene angakhudzidwe ndi mitsempha trigeminal?

Matenda a sitiroko ake predisposes kuti channelopathies chitukuko - siudzalandilidwa ngathi lamulo mitsempha nthambi kudutsa njira kapena ndime ozungulira formations. Pankhaniyi, chidziwitso cha zimachititsa chilumbachi wa mitsempha, ndi zizindikiro zina apakhungu limakupatsani anapereka mlingo wa kugonjetsedwa ndi kanthu moyenerera.

Chinanso ofunika ndi chikoka zimakhala ozungulira. Ambiri zambiri misempha bwanji chotupa mu ubongo. Anatsegula, iwo amathandiza kuti psinjika maonekedwe ake ndi makamaka matenda chithunzi.

Matenda a mitsempha trigeminal (nzeru nthambi zake ndi malo pa ziyerekezo nkhope) kudziwa kuchoka mfundo ya nthambi mitsempha, ndi njira electrophysiological kuchita yotithandiza iwo, kapena kupatsidwa malo pa nthambi, agwire chithandizo choyenera cha matenda vutoli, zomwe zinachititsa kuti maonekedwe a zizindikiro.

Kuphunzira mitsempha trigeminal

Kuphunzira ntchito ya mitsempha trigeminal amachitika kudziŵa tilinazo khungu, amene innervates, komanso luso wodwalayo kuti mantha ndiponso kumasuka minofu ya kutafuna. Kafukufuku ndi mfundo palpation mitsempha pa kuchoka nkhope yake. Kodi mungadziwe bwanji tcheru mitsempha trigeminal? Kaswili chololera kudziwa ntchito manyuroni kwenikweni, yomwe ili pansi pa khungu.

Khama la tilinazo ikuchitika choviikidwa mu njira wozizira kapena wotentha kapena thonje swab. Ululu tilinazo kufufuzidwa ndi masingano olimbikitsa.

Kufufuza galimoto ntchito ya wodwala kuti mugwire magulu angapo kutafuna.

Pamaso pa kusintha pathological zimawonedwa mu tilinazo mu mabacteria chimodzi kapena zingapo innervation kapena kulephera kwa mtima kuchita bwino kutafuna kayendedwe. kupatuka nsagwada mbali mmenemo mtima kapena minofu kwambiri kuphipha. The mavuto minofu masticatory anatsimikiza pamene mbamuikha ndi iwo akuchita kutafuna.

Kodi mukufuna kudziwa zimachititsa chilumbachi

Mtunda thunthu la mitsempha trigeminal M'pofunika mtima molondola m'dera chotupa. Podziwa komwe ndi zimene nthambi, omwe zizindikiro matenda khalidwe chifukwa chogonjetsa ake ndi zimene iwo akhoza kumva, n'zotheka kudziwa voliyumu ndi chithandizo dongosolo.

Kudziwa malo ndi njira ya nthambi za mitsempha apuma pa mapewa a Madokotala aubongo ndi neurosurgeons. Ndi akatswiri izi makamaka akakumana ndi matenda amene anapha mitsempha trigeminal. Kaswili (chithunzi akamagwira Kujambula) kudziwa machenjerero mankhwala ndi kanthu moyenerera.

Zizindikiro loyamba zotupa osiyanasiyana nthambi mitsempha ayenera yomweyo kupempha thandizo kwa dokotala kupanga matenda ndi mankhwala zojambula aligorivimu.
