Anatomy of trigeminal etsinga uye awo

Tsinga ndivo hwaro tsinga. Vazhinji vavo vane cranial, kuti ari kuuya achibva uropi. wakadai ndiye trigeminal etsinga. Chii anatomi pamusoro trigeminal etsinga?

Chii?

Trigeminal tsinga ari mamiriro ndiyo etsinga ari yakavhenganiswa mhando. 5 inotaura kuti peya cranial tsinga.

Rinosanganisira nzwisisa (afferent centripetal) uye injini (Centrifugal) fibers apo pamusoro etsinga nomunhu zviri zvitange zvose pachiso (marwadzo netembiricha) uye rakadzika (proprioceptive) receptors. The propulsion injini innervation akatakurwa chinoumba iyo innervates masticatory tsandanyama kunyanya. Chii chaizvo ndivo anatomi pamusoro trigeminal etsinga uye localization awo?

Tsinga kunosiya uropi munharaunda yacho zambuko. Achibva uropi, uzhinji zvaitika pamusoro piramidhi pakati zvenyama mapfupa. Pamusoro pane kupesana mukati matavi matatu etsinga: orbital (r.ophthalmicus), maxillary (r.maxillaris) uye mandibular (r.mandibularis).

tsinga iyi inofarirwa neurologists kubva innervates yose chiso nzvimbo. Kazhinji vakachengeta kukundwa ake panguva supercooling, kunotevera pachiso nharaunda, zvimwe zvirwere zviri zvetsandanyama nemapfupa hurongwa.

Ndezvipi anatomi pamusoro trigeminal etsinga uye awo?

orbital tsinga

The bazi trigeminal etsinga wokutanga tsinga kana orbital nervus ophthalmicus.

Ndicho thinnest matavi yaidzika kubva trigeminal etsinga. Iye anoita kunyanya mashandiro mabiko. Innervate paganda pahuma, zvimwe zvikamu zvenyama parietal nharaunda, rokumusoro pachifunhiro charo, seri mhino, sinuses, vamwe mapfupa chiso uye ubatanidzwewo nasal mucosa.

Sechivako etsinga rine mwanda zviduku vanenge makumi matatu tsinga fibers. Tsinga anopinda ziso panosangana rusvingo rwokunze orbital sinus, iyo anotumira bazi kuti nechigumbuso uye abducens. In rokumusoro orbital etsinga clippings vanoparadzaniswa kupinda matatu maduku uye dzakaonda danda - lacrimal, frontal uye ciliary tsinga.

Close localization yeziso kazhinji kunotungamirira kukundwa kwavo pamusana yokukuvara kana ziso zvigadziko supraorbital nharaunda.

Ciliary tsinga, uyewo, anoumba ciliary ganglion, riri pamuganhu yomukati uye pakati chetatu pamusoro optic etsinga. Inoitwa pakati parasympathetic etsinga harinzwi munyaya innervation weziso omumuviri, uye periorbital nharaunda.

maxillary tsinga

Rimwe bazi trigeminal etsinga ndiwo maxillary kana nervus maxillaris.

Anobva cranial mhango kubudikidza foramen ovale. Kubva, iye muwisira pterygopalatine-palatine fossa. Kupfuura mairi kupinda infraorbital etsinga Kunoguma rezasi orbital buri. Apfuudza therethrough, tsinga anomhanya chete mugero mujinga pasi parusvingo muchadenga. Pachiso chinobuda kuburikidza rezasi orbital buri apo rinotsemuka kupinda mapazi madiki. Vanoumba remubatanidzwa pamwe mapazi ari chiso etsinga uye innervate ganda rezasi fungiro, yokumusoro muromo uye parutivi pechiso chake. Uyezve, maererano maxillary etsinga bazi hake akadai zygomatic tsinga alveolar yokumusoro bazi achiumba interlacement akapoteredza mazino uye matavi ganglionic unobva maxillary etsinga pamwe pterygopalatine ganglion-palatine.

The kukundwa etsinga iri kuchengetwa mukunyombwa mikuru vanosangana, neuritis, akavhiyiwa pamusoro mazino uye sinuses.

mandibular tsinga

Wechitatu uye kuoma bazi trigeminal etsinga ndiwo mandibular kana nervus mandibularis. In kwayo sezvamunoita chine, kunze mapazi nehanya, zvinenge zvose injini pamudzi trigeminal etsinga kuti rinoenderera injini musimboti, musimboti motorius, kuti tsandanyama repasi shaya. Somugumisiro ichi urongwa anopa mashoko tsandanyama uye ganda kuti kunovafukidza. Tsinga haazotaurwizve dehenya kuburikidza foramen ovale (denderedzwa hwindo kana achizarura) uye zvadaro mapoka mapoka maviri awo:

• matavi tsandanyama kuenda masseter tsandanyama - pterygoid tsandanyama, zvenyama; innervated uyewo musculus digastricus.
• Mapazi ndiwo inonyatsoziva buccal mucosa, uyewo pasi nomumukanwa mhango. Chikamu matavi innervate humboo uye mutauro. The Kudeuka uye chakarebesa bazi mandibular tsinga - alveolny hwakaderera (dzimwe manyuko - alveolar) tsinga ichipfuura pfungwa foramen pamwe homonymous tsinga uye anoenda kunzvimbo dzapasi shaya chiteshi aumbwa apo rezasi alveolar plexus.

Tinogona kufungidzira kuti chinhu bazi trigeminal etsinga mberi. Anatomy dhayagiramu tsinga (mamiriro) uye zvivako ayo (yakavhenganiswa tsinga faibha) anoratidza ichi bazi inouraya. Pasinei anoumba muduku alveolar etsinga plexus, nzvimbo Payakapera Zvingaonekwa suo mandibular mugero.

Weboka etsinga fibers

Chii anatomi ari trigeminal etsinga (marongerwo uye mberi awo)?

The Chimiro akafanana ari trigeminal etsinga mumwe musana tsinga. The trigeminal tsinga huru inokosha chairema - the trigeminal ganglion. inotungamirwa ichi riri mukati cranial fossa. Kumativi ose rakakomberedzwa machira reDhura mai. Raiva pedyo nebundu ane dendrites kuti vanoumba zvitatu zvikuru matavi vakuru trigeminal etsinga. Nzwisisa tsinga mudzi chinopinda nepakati cherwendo cerebellum, apo akadzivira pamusoro nuclei matatu uropi - rokumusoro uye pakati, imwe neimwe ine chaiwo kutsinga dzinouya Tutsinga tunofambisa mashoko utwu. Injini Chikamu etsinga rinotanga kubva injini musimboti - neerekitironi motorius.

Nemhaka iyi urongwa, etsinga inogona akafumurwa vose uropi uye dzakapoteredza rinenge uye nokudaro inofarirwa neurologists.

Zvirwere trigeminal etsinga

Chii pezvakaitwa kunge kwakabatsira pamusoro dzichipfekeka vachikwanisa dzidzo uye nzira iyo dzingave dzawirwa kubudikidza trigeminal etsinga?

Anatomy sitiroko yayo predisposes kuti budiriro channelopathies - kukanganisa tsinga mapazi nomunyika gwara kana ndima dzakapoteredza idzodzo. Muchiitiko chino, zivo kwakaita nzvimbo yacho yose etsinga, uye vamwe kukamura uchishandisa zviratidzo unokubvumira kuisa ufanane kukundwa uye chiito chakakodzera.

Chimwe zvakaenzana chinokosha ndiko kufurira kwakaita akapoteredza munyama. Kakawanda iri tsinga sei rouropi. Kuparidzira, ivo pave compression chitarisiko chake uye zvikurukuru kunotoda mufananidzo.

Anatomy of trigeminal etsinga (zivo awo uye nzvimbo pamusoro fungidziro chiso) kuziva mbudo pfungwa pamatavi etsinga, uye electrophysiological nzira chiito kuti akurudzire navo, kana, kupiwa nzvimbo bazi, vaite yakakodzera pakurapa chaicho chirwere, izvo zvakazoita kuti pakuonekwa zviratidzo.

Kudzidza trigeminal etsinga

Kudzidza kushanda trigeminal etsinga chiri kuitwa Pakusarudza aikanganiswa ganda, icho innervates, uyewo murwere anogona kusununguka uye Tsandanyama dög. Research kuitwa palpation tsinga dzinokosha dzaro mbudo chiso. Sei kuziva kuti vasanonoka ari trigeminal etsinga? Anatomy kunoita kuti tizive basa kutsinga dzinouya Tutsinga tunofambisa mashoko utwu, raiva pasi ganda.

Kutsunga of nehanya rinoitwa dzichinyikwa kuchitonhora kana kupisa mhinduro kana donje swab. Marwadzo utetsa atariswa bata tsono.

Kuongorora injini kushanda murwere akakumbirwa kuita wandei dög masangano.

In pamberi pathological shanduko iri kuchengetwa ari aikanganiswa rimwe kana kupfuura zvikamu zviri innervation kana nekusagona murwere kuita zvakanaka kutsenga kufamba. Pane kutsauka shaya divi mune murwere kana kunyanyisa tsandanyama spasm. Makakatanwa ari masticatory tsandanyama akatsunga kana waitsimbirira navo achiita dög.

Zvaunofanira kuziva kwakaita nzvimbo yacho

Topographical anatomi of trigeminal etsinga inodikanwa kutsunga yakarurama lesion nzvimbo. Kuziva iripiko iro davi, izvo kurapwa zviratidzo mamirire ayo kukundwa uye chii vanogona kuva kwakaoma, zvinokwanisika kuti kuona vhoriyamu uye kurapwa kuronga.

Zivo nzvimbo uye nzira mapazi etsinga hunogara pamafudzi neurologists uye neurosurgeons. Zviri nyanzvi aya kunyanya nemamiriro nezvirwere kuti akarova trigeminal etsinga. Anatomy (Mufananidzo yaunganidzwa MRI) kuti asarudze kurapwa nzira uye chiito chakakodzera.

Nezviratidzo maronda yakaipa bazi tsinga anofanira pakarepo kutsvaka rubatsiro kune mumwe chiremba kuti chirwere uye kurapwa mufananidzo algorithm wokutanga.
