Anatomy of the luvo trigeminal amasebe awo

Luvo asisiseko kwinkqubo luvo. Inkoliso yabo cranial, into ephuma ebuchotsheni. lowo unjalo ke luvo trigeminal. Yintoni na kwendlela ezakhiwe ngayo luvo trigeminal?

Yintoni na?

luvo Trigeminal kwi sakhiwo luvo lohlobo exutyiweyo. 5 ibhekisa iperi luvo cranial.

Oku kuquka sensitive (centripetal afferent) kunye (centrifugal) Imicu iimoto, apho kwi amaza luvo kudluliselwa omabini ukusuka kumphezulu (intlungu lobushushu) zinzulu receptors (proprioceptive). Le nezingenayo motor innervation core olwenziwe leyo innervates izihlunu masticatory kakhulu. Yintoni kanye kanye le kwendlela ezakhiwe ngayo luvo trigeminal kunye lizwe amasebe awo?

Nerve ushiya ingqondo kwingingqi kwebhulorho. Bephuma ingqondo, uninzi kuthatha indawo kwi iphiramidi wethambo zexeshana. Emantloko kukho ukwahlulwa ibe amasebe ezintathu luvo: Orbital (r.ophthalmicus), maxillary (r.maxillaris) kunye mandibular (r.mandibularis).

Olu luvo kwenza umdla neurologists ukususela innervates indawo yobuso yonke. Lidla wabona kwakhe ngexesha supercooling, kwentlungu indawo yobuso, ezinye izifo kwenkqubo musculoskeletal.

Yintoni na kwendlela ezakhiwe ngayo luvo trigeminal kunye namasebe ayo?

luvo Orbital

Isebe lokuqala luvo trigeminal i-luvo okanye Orbital nervus ophthalmicus.

Yeyona amasebe thinnest elandisiweyo ukususela luvo trigeminal. Yena owenza ikakhulu umsebenzi ulwamkelo. Innervate isikhumba ebunzi, ezinye iindawo zaloo mmandla zexeshana kunye Parietal, isiciko eliphezulu, ngasemva impumlo, sinuses, ezinye amathambo zobuso kunye isifo ngokungaphelelanga ngeempumlo.

Indlela esakhiwe ngayo esi-luvo yenziwa malunga namashumi amathathu iinyanda omncinane of luvo. Nerve engena kwisokethi amehlo udonga olungaphandle sinus Orbital, ethumela isebe ukuba ibhloko kunye abducens. Kule eliphezulu ezisikwe luvo Orbital yahlukanisiwe ezintathu ezincinane ebhityileyo umqadi - lacrimal, ngokungqalileyo kunye imithambo ciliary.

Vala kwasendaweni lweliso lakho kukhokelela ukoyiswa kwazo ngenxa yokulimala okanye iziseko iliso mmandla supraorbital.

luvo Ciliary, nayo, yakha ganglion ciliary, sise emdeni yesithathu yangaphakathi ophakathi kwe-luvo optic. Luquka ezi kwalapho parasympathetic inxaxheba innervation kwamadlala iliso, yaye indawo periorbital.

luvo maxillary

Elinye isebe le-luvo trigeminal ke maxillary okanye nervus maxillaris.

Ushiya kwisisu cranial ngokusebenzisa ovale foramen. Ukusuka kuyo, iwela le fossa pterygopalatine-iPalatine. Watyhutyha kulo waya luvo infraorbital kunabela kulo mngxuma esezantsi Orbital. Emva kokuphumelela therethrough, luvo ubaleka itshaneli enye eludongeni emazantsi okuwo. Ngomhla ubuso iphuma kumngxuma esezantsi Orbital apho iqhekeka ngokwamasebe ezincinane. Bakha ezimbaxa kunye amasebe ye-luvo yobuso kwaye innervate isikhumba ijwabu asezantsi, iindevu kunye umphezulu ecaleni ebusweni. Ngaphezu koko, yi maxillary nemithambo mabaphume sebe ezifana luvo zygomatic yesebe ephezulu alveolar ezenza interlacement ngeenxa zonke emazinyweni kunye namasebe ganglionic anxibelelanisa luvo maxillary kunye pterygopalatine ganglion-iPalatine.

Ekubulaleni luvo elifana neli kakubi amakhulu nazo, neuritis, imisebenzi amazinyo kunye sinuses.

luvo mandibular

Isebe lesithathu kwaye enzima luvo trigeminal ke mandibular okanye nervus mandibularis. Kumafa yayo kuye, ngaphandle amasebe ezibuthathaka, phantse zonke motor ingcambu luvo trigeminal esentlango, ephuma ngumongo motor, motorius ngumongo, kwizihlunu kwemihlathi asezantsi. Ngenxa yale lungiselelo onikezela izihlunu data nesikhumba elihambelana kubo. Nerve lukhupha ukakayi ngokusebenzisa ovale foramen (window elimbhoxo okanye ukuvulwa) waza wabahlula bangamaqela amabini amasebe:

• amasebe imisipha yiya esihlunwini masseter - umsipha pterygoid, zuzwana; innervated kwakhona digastricus musculus.
• Amasebe abaqaphela ukuba isifo buccal, kwakunye ukuya ezantsi kwisisu ngomlomo. Inxalenye yamasebe innervate iinkcukacha kunye nolwimi. Isebe mandibular luvo kwelikhulu elide - alveolny elisezantsi (kwezinye imithombo - alveolar) luvo udlula kulo foramen ngengqondo kunye Umthambo homonymous kwaye ingena emhlathini channel esezantsi luqokelelane apho plexus esezantsi alveolar.

Kuthathwa ukuba isebe le-luvo trigeminal uqhubeka. Komzimba umzobo-luvo (isakhiwo) kunye neempawu zayo (mixed nemithambo ifayibha) iyayixhasa le terminal sebe. Nangona yokuba yakha encinane alveolar luvo plexus, indawo lokugqitywa kwaso ingqalelo isango lomsele mandibular.

Le khosi ye-luvo

Yintoni na kwendlela ezakhiwe ngayo luvo trigeminal (isakhiwo kunye nenkqubela amasebe awo)?

Isakhiwo iyafana naleyo luvo trigeminal kuyo nayiphi na spinal luvo. I-luvo trigeminal ukuba iyunithi eyodwa enkulu - ganglion trigeminal. Le owabumba ibekwe kwi fossa phakathi cranial. Macala onke kokuba ingqongwe amaphepha laseDura mater. Izokhula luvo ukuba zibe amasebe amathathu ezinkulu oyintloko luvo trigeminal. Ezinobuzaza ingcambu luvo ingena ngokusebenzisa umlenze phakathi kwiCerebellum, apho zivaliwe phezu nuclei ezintathu yobuchopho - engasentla nophakathi, ngamnye equlethe luvo ezithile nemizwa. Le motor yinxalenye luvo iqala ukusuka motor isiqalo - motorius ngumongo.

Ngenxa yeli lungiselelo, i-luvo nga bazakubhentsiswa zombini ingqondo izihlunu ezingqongileyo, yaye ngaloo ndlela 'umdla neurologists.

Zeziphi iintlobo eziphambili izilonda uphawu-luvo?

Izifo luvo trigeminal

Yintoni iinkqubo kukho ifuthe lale ngxaki kumandla esebenzayo yemfundo kunye nendlela ekuya kuthi na ochatshazelwa luvo trigeminal?

Anatomy of inxeba lalo predisposes ukuya channelopathies zophuhliso - amasebe luvo lwentengiso edlula umjelo okanye umhlathi namabandla ezingqongileyo. Kulo mzekelo, ukwazi isimo se le-luvo, yaye ezinye iimpawu mlonyeni ikuvumela ukuba ukucwangcisa izinga ngokoyiswa ze athathe amanyathelo afanelekileyo.

Enye into ebalulekileyo ngokulinganayo impembelelo emzimbeni ezingqongileyo. Amaninzi kwi-luvo kuchaphazela ithumba ebuchotsheni. Ukwandisa, eziphuhlisa ngayo ucinezelo ngenkangeleko yakhe kunye nomfanekiso ethile lwezonyango.

Anatomy of the luvo trigeminal (ulwazi amasebe awo kunye neendawo phezu kobuso projektha) ukumisela kwindawo uphume amasebe-luvo, yaye iindlela electrophysiological amanyathelo ukukhuthaza kubo, okanye, banikwe indawo kwesebe, enze ukuba unyango olufanelekileyo kwesi sifo engundoqo, nto leyo eyakhokelela ekubeni ukubonakala iimpawu.

Uphononongo lwe-luvo trigeminal

Ukufunda umsebenzi luvo trigeminal luqhutywa ekugqibeni uvakalelo ulusu, leyo innervates, kwakunye kumandla umguli ngayo ixesha imisipha ehlafuna. Uphando olwenziwe ngamanqaku Ngokucofa luvo ebusweni bayo exit. Njani ukuba indlela ophulaphula ngayo ethe yaba trigeminal? Anatomy ukuvumela ukuba ukujonga umsebenzi luvo yovakalelo, ibekwe phantsi kwesikhumba.

Ukumiselwa-ethe yenziwa nkxu isisombululo abandayo okanye ashushu okanye cotton kwasala. Pain uvakalelo zitshekishwe neenaliti echukumisayo.

Ukujonga umsebenzi lwemoto yomguli ecelwa ukuba enze iintshukumo ihlafuna eziliqela.

Xa kukho utshintsho zophendlo lwezifo uyaqapheleka uvakalelo kwimimandla enye okanye ngaphezulu innervation okanye ukungakwazi isigulane ukwenza iintshukumo ukuhlafuna kakuhle. kwicala ukuphambuka umhlathi Apho kumguli okanye ngokugqithiseleyo spasm kwezihlunu. Ingcinezelo kwizihlunu masticatory uzimisele xa licinezelwe kubo isenzo ehlafuna.

Into ekufuneka uyazi-mphandle

komzimba ukuma komhlaba i-luvo trigeminal kuyimfuneko ngokuzimisela echanekileyo indawo sisilonda. Ukwazi uphi na apho isebe, apho iimpawu zonyango iimpawu ngokoyiswa bayo, bungakanani zibe lukhuni, kunokwenzeka ukuba ukumisela isicwangciso umthamo kunye nonyango.

Ulwazi indawo ikhondo amasebe luvo luphezu kwamagxa neurologists kunye neurosurgeons. Kuyinto le iingcali ezijongene ikakhulu abanezifo liwubethileyo loo mfanekiso luvo trigeminal. Komzimba (photo ezifunyenwe yi MRI) ukufumanisa amaqhinga unyango ze athathe amanyathelo afanelekileyo.

Yimiqondiso zokuqala izitshanguba ezahlukahlukeneyo yesebe luvo kufuneka ngoko nangoko kufuna uncedo kugqirha ukuba afunyaniswe isifo kwaye afumane unyango zokuzoba algorithm.
