Vestibular cochlear tsinga: tsananguro, mamiriro uye anatomi

Anatomists oga gumi yegwara tsinga kuti vane chaiyo inoshanda uye dziri mukati musoro uye mutsipa. Mumwe wavo ari vestibulocochlear etsinga. Ndiye anokonzera rinokosha nehanya: kunzwa uye pfungwa mwero. Kukanganisa yakaitwa ake kana kushanda kungaita kuti zvikuru urema kodzero.

mamiriro

Ndeipi vestibulocochlear etsinga? Anatomy zviri zvikuru yakaoma, sezvo hwaro zita, inoumbwa vaviri yoga mudzi, nedzimwe mabasa. Chokutanga - the vestibular, riri basa mwero uye anopa semicircular migero womukati nzeve. Second - kunzwa, anoitisa nomunhu kubva labyrinth pamusoro cochlea kuna nomuzongoza.

Tsinga anotora kwayakatangira nechepasi pemvura hemispheres, vachisiya vachena nyaya iri muorivhi nuclei ari medulla oblongata uye Vakazopinda pazasi kuti chiso etsinga. Auditory bazi rinotanga kubva raiva pedyo nebundu iri cochlea, uye peripheral ayo pezvakaitwa vanoguma ari zononoka muviri uye nechepakati migumo kuburikidza pamusoro chepiramidhi mapfupa auditory muuropi uye zvasvika cochlear nuclei.

Chechipiri, vestibular, bazi uyewo chinotanga nodule, riri munzeve. The dendrites pamusoro Tutsinga tunofambisa mashoko utwu izvi kuenda semicircular yaNire, idenderedzwa uye elliptical muhomwe. A axon sezvo chikamu vestibular mudzi rwunotumirwa nedhaimani serin'i gomba uye inoguma ikoko, muna vestibular nuclei.

kupa kunzwa

Zvinoita Maonero evanhu kwava nani kunzwisisa. Ikoko rokunze, pakati uye yomukati nzeve, asi vestibulocochlear tsinga innervates chete mukati. Chokutanga, ruzha panoonekwa eardrum. oscillations ayo hwakatamisirwa nyundo, panhera uye stirrup, izvo interconnected. With sefungu kunokanganisa stapes denderedzwa hwindo, rakamiswa pamusoro avaida inovhiringidza. Vibrations kukonzera misha yacho perilymph uye endolymph mukati inovhiringidza. Oscillate pamwe nemvura uye yechipiri zvikamu eardrum, iyo basilar kana ndiro. Pairi vari zvukovosprinimayuschego bvudzi, generating tsinga nomunhu. Zvinonzi chakasvitswa kune helical Unit, riri munzeve. Pezvakaitwa masero etsinga anoumba raiva pedyo nebundu yaiva kuburikidza buri nzeve Canal uye, unobatanidza pamwe vestibular etsinga, enda zambuko, sezvamakaropafadzwa nefuma uye mugumo cochlear nuclei mune rhomboid fossa.

cochlear neuronal axons piringisha uye kuumba lateral loop. The fibers vari ipapo vakaparadzana. A duku chikamu inoguma musi rezasi hillocks quadrigemina ndiro (midbrain). The zororo anoenda medial geniculate miviri iri diencephalon kana medial thalamic neerekitironi.

nepakati basa

Nokuti pakuenzanisa muviri nzvimbo panguva kufamba uye ndakazorora kuri kukonzera vestibulocochlear tsinga. Driving innervation wayo kubva uninitiated angaita romuromo kuti nechokwadi kuti basa iri kunoda synchronous nokushanda dzakawanda tsinga.

Kunyatsoongorora zvakanyatsoenzana

Vestibulocochlear tsinga kuri kukonzera nechiyero, saka neurologists mu Integrated rokuongorora kazhinji vanoguma vava miedzo yakasiyana-siyana kuti aone kurwisa murwere:

1. Romberg kuti bvunzo - chimwe chezvinhu zvakafanana kusarudza. Murwere akakumbirwa kumira chaizvo zvokuti tsoka dziri chete mutsetse, uye chitsitsinho rutsoka rimwe akazorora pamusoro yechipiri toe. Hands zvinofanira kuzununguswa voga kana zviri mberi. Chiremba akabva abvunza kuti nhanho shomanana mberi kutanga asvinudzwa meso enyu uye ipapo yakavharwa. Unsteadiness kuti gait kana yechipiri inoreva rwomukati kukuvara nzeve.
2. Test Mittelnaera. Murwere anofamba pasi nameso ake akavharwa. Kana paine kukundikana vestibular midziyo, ipapo zvishoma nezvishoma Achadzorera kurutivi wechoto.

Rokukunda cochlear bazi

Kukurirwa vestibulocochlear tsinga panzvimbo basa processing auditory pulses ane chaiwo zvekuchipatara kuratidzwa. Pane vaviri kuzvidzora kuita:

- inzwi conduction kukanganisa, kana conductive kusanzwa (pakati nzeve chirwere);
- sensorineural kusanzwa mu maronda womukati nzeve.

In aimbova nyaya kunokonzera zvinhu zvingava anogumbura, kana neoplastic zvinyama kuoma dzimwe nhengo dzomuviri chirwere. Second zvirwere musimboti kunogonawo kukonzera anogumbura mananara, neuroma, uye zvinhu nemwongo nzvimbo nuclei nzvimbo rorusere cranial tsinga.

Akaora kunoratidzwa kunyunyuta pamusoro ruzha munzeve, nomusoro, vakawanda kuderera vachinzwa. Kana pathological muitiro muuropi mukobvu, zvingava akaona kurasikirwa mabasa uye pedyo tsinga, dzakadai vestibular, chiso uye trigeminal. commonality kwakadaro nezviratidzo anonzi "rakatumbuka hemiplegia."

The kukundwa of vestibular

Zvokurwara vestibulocochlear tsinga kune vestibular mugove bazi achatanga unooneka dzungu, kuda kurutsa (dzimwe nguva kurutsa) uye nystagmus. tsinga Izvi pamwe kukonzera mamiriro ezvinhu eyeballs apo nzvimbo musoro, saka kana kukundwa yake angava nokuchinja ziso kufamba. Kureva kudzika chinjikira kana tote jerks.

Mukuwedzera, murwere ane kusagadzikana gait, uye iye anofanira straddle (sezvo mungarava panguva yokukandwa) kuchengeta kunyatsofunga, uye kuramba kuongorora tsoka dzavo. Naizvozvo, vanhu vakadaro vane chiremba anogona kureva nechirwere panguva Vakati vapinda muhofisi yake.

Neuroma vestibulocochlear tsinga

Innervation vestibulocochlear tsinga kunoratidza kuti anofukidza internet mumuhara kuti Schwann masero. mhando iyi kuputira kuti tsinga zvairatidza haisi kune dzimwe fibers. Asi kubva muchitokisi membranes, mu zvisingawanzoitiki zviitiko (zviuru zana) anogona kukura munhu benign bundu.

Kunoratidza pacharo zvishoma nezvishoma uye, sezvo mutemo, kana bundu yakatotanga asvika rebei saizi. Varwere vanotsutsumwa kuti kunzwa sokurasikirwa rimwe divi, dzungu, kurwadziwa kurutivi chiso, uye kuvapo comorbidity chiso uye abducens. Izvi vakaratidzawo kutaura impairments, nematambudziko kudya. Bundu anorumanya manzwiro, iro rinoita yakakodzera kiriniki.

Kana neuroma vaibva kumativi ose, murwere inokurudzirwa zvakaitika majini kuongororwa rakadaro kuvapo neurofibromatosis (nhaka connective zvinyama chirwere). Treatment Kazhinji zvomusejari.

Meniere kuti urwere

Vestibulocochlear tsinga kunogona wakaremara zvisina kunanga muna Meniere chirwere. Pacharwo zvokurwara chokuita havachanyatsogoni kugadzirwa uye water drainage pamusoro mvura munzeve. Her oversupply anoisa kumanikidza nehanya bvudzi, izvo kunooneka pacharo mu disequilibrium.

Akaratidza chirwere yokurwiswa vertigo achiperekedzwa tinnitus uye kunzwa zvizere njodzi divi. Uyezve, varwere chokunyunyuta pamusoro mberi kusanzwa. Sezvo chirwere mberi, zviratidzo achiipa, uye zvingava kusvikira munhu munguva nezvokubvuta haagoni kumuka uye vakatendeuka musoro wako.

Treatment ipfupi zvakazorodza kuti kusagadzikana panguva kurwisa uye kugamuchira sedatives mune lucid zvikamu. Kana kuchinja mabatiro asingadi kubatsira kuti kuita zvikuru rinoreva nokuparadza vestibular labyrinth kana muchinjikwa bazi vestibulocochlear tsinga.
