Laíaanta: goobta, shaqo, guuldaradii

Qof walba dugsiga ogyahay oo ku saabsan 12 lammaane oo dareemayaasha cranial. Waxay mashquulin jagooyinka muhiimka ah ee shaqaynaya ee habka dareemayaasha jirka. jebinta kasta oo ay shaqada weeyaan jebinta shaqeeyo oo dhan. Sidaas laíaanta iska leh labada afaraad.

Meesha ee maskaxda

Way adag tahay in la fahmo waxa waana meesha aan diyaarinta jidh. Sidaa darteed, sharaxaad faahfaahsan ka akhriso goobta dareemayaasha. Sayidka, labada afraad waa mid ka mid ah oo kaliya in uu aado xagga dambe ee stem maskaxda. At heer ah oo kuraha hoose ee dareemayaasha block core Masaarida maskax. Haddii aad eegto dhinaca hore, waxay ku yaalaan weeraryahanka xaalka cirro dhexe. Marka la eego ka nuclei ka mid ah dareemaha oculomotor block dareemayaasha xuduntii ku yaal hoose.

chiasm dareemayaasha Trochlear foomamka waslad khafiif ah oo cawl waxaa lagu magacaabaa dhoofnay cerebral kuwaas oo foomamka ventricle dabool leh. Ka dib markii dareemaha baxo iyada oo maskax ilaa hoos ah oo kuraha hoose. lamaane kasta oo tagaa agagaarka stem maskaxda ka dhanka ah. Waxaa jira dareemaha block a guskiisa galay farqiga u dhaxeeya xuubka temporal iyo maskaxda stem maskaxda. Ka dib markii uu horay u socdo, uu guskiisa Mater Duuraa derbiga sare ee sanka ka cavernous ah. Waxaa, iyada oo Waasac sare orbital gaadho falagiisuu iyo aado muruqa sare uugu ee isha.

Laíaanta: shaqo, la dhexgalo oo laba laba kale oo dareemayaasha

Ujeedada ugu weyn ee labada afraad ee dareemayaasha cranial - si loo hubiyo in dhaqdhaqaaqa isha Weeraryahanka iyo hoos. Caadi ahaan bu'da ayaa faasas badan oo wareeg. Wadar ahaan lix muruqyada ku lug leeyihiin geeddi-socodka. Sayidka kala saaro indhaha u noqon oo macbudyo ah, sanka, kor u qaadaya oo hoos u soo dejiyey. Muqaalka muhiimka ah ee isha aadanaha - mooshinka wadajir ah, sida dadka caadiga ah ma arki karaan indhaha ee jiho oo kala duwan. Sidaas daraaddeed, oculomotor, trochlear iyo abducens ka mid ah tirada guud ee kooxda ee dareemayaasha oculomotor. failure ee xisbiga kasta oo xadgudub ku tahay shaqo muuqaal ah. Sidaas darteed, waxaan sawiri kartaa gabagabadii soo socda:

• dhaqdhaqaaqa indhaha go'doon suurtogal maaha;
• Labada indhaha ka guurto waqti isku mid ah;
• had iyo jeer waxay yaraysaa labada murqaha isha.

Hababka waxbarasho

Si loo go'aamiyo inuu hawlaha ama labada ciyaaryahan in dareemayaasha cranial, dhakhaatiirta isticmaalaan hababka gaarka ah ee baaritaanka si sax ah. Si arrintan loo sameeyo, ka fiiri si aad u aragto haddii qofku qabo aragga oo labalaabma. dillaacyada xeeldheer width palpebral, size ardayga, booska uu ka bu'da. Daraasad lagu ogaanayo Muhiim ah - falcelinta ee ardayga Iftiin. Si arrintan loo sameeyo, bukaanka ayaa laga codsaday in ay indhahana isagoo gacmaha iyo iyaga iska fogeeya, eegaya nuurka. Si aad u barato wada ee dubbe caadiga ah isha isticmaalo. Its u dhaw in ay buundada, hubinta wada ah oo tufaax ah. Hoyga baaro xataa fudud: bukaanka xirmin isha, kii labaadna wuxuu eegayaa marka hore on shay fog, ka dibna ay xirto.

guuldaradii of block dareemaha: Calaamadaha iyo Daaweynta

Tan iyo markii shaqada ugu weyn ee labada afraad ee dareemayaasha cranial - motor, iyo ugu horeysay ee weyn ee calaamad - qallal. bu'da weecasho A upwardly iyo hoosta. Tan waxaa si cad u arkin marka bukaanka waa on sallaan ku. calaamad kale - aragga oo labalaabma, ka mid ah ciidamada u hagaagsan sida in la odoroso image ah in qaybaha kala duwan ee ileyska xasaasiga ku ah.

Iyada oo guuldaradii ee dareemayaasha oculomotor la arkay sawirka soo socda: isha aan dhaqaaqin, ardaygu uusan fal ay iftiinka. Haddii ay taasi dhacdo labada indhoodba, ka dibna waxaan kala hadli kartaa oo ku saabsan guuldaradii of nuclei dareemayaasha.

Inta badan waa natiijo ah oo horumarinta cudurada sida neurosyphilis, meningitis, calaamad u ah aneurysm, thrombosis, iyo kuwa kale. Sidaa darteed, waxaa muhiim ah in la daweeyo sababta in la baabi'iyo xaaladda ka.

Si aad u taariikhda, ma jiraan habab wax ku ool ah ee daaweynta ee dareemayaasha oculomotor. Sida laga soo xigtay xogta waxa uu ahaa guul leh codsatay daaweynta dabiiciga ah, oo ay khasaare oo kaliya - saamayn gaabis ah ama ay ka maqan. Si laíaanta mar kale bilaabay inuu u shaqeeyo, inta badan loo isticmaalaa dareenka korontada ah.

Si kastaba ha ahaatee, daaweynta waa in kaliya la fuliyaa by dhakhtarka. Marka lammaane dareemayaasha cranial fiican in la isticmaalo hab isku dhafan oo ku lug leh farsamooyinka dhowr. Waxaa muhiim ah in la bilaabo geedi socodka cudurka, sida horumarinta waxyeellada dareemayaasha waxaa diirkja doono, taas oo yaraynaysa fursadda dib u soo kabashada si weyn.
