Study Notes

Organo de audito e equilibrio (organum vestibulocochleare)

  • Le presentation concerne le cavitate tympanic e su contento.
  • Il es presentate per Dr. Tamás Andrea.

Partes del systema de organos de audito e equilibrio

  • Le systema consiste de tres partes principal:
    • Aure externe (auris externa)
    • Aure medie (auris media)
    • Aure interne (auris interna)

Aure Externe (Auris Externa)

  • Compone le parte le plus externe del systema de audito.
  • Es componite del sequente:
    • Auricula (pinna)
    • Meato acustic externe
    • Membrana tympanic

Auricula

  • Le cartilagine auricular (cartilago auriculae) es facite de cartilagine elastic.
  • Structuras prominente include le fossa triangularis, concha, tragus, antitragus, helix, antihelix, scapha e lobulo auricular (lobulus auriculae).

Musculos del Auricula

  • Innervate per le nervo facial (n. facialis).
  • Il ha musculos auricular anterior, superior e posterior.

Innervation cutanee del auricula

  • Le nervo auriculotemporal provide innervation.
  • Nervos vagal e glossopharyngeal contribute al innervation.
  • Assi, le nervo facial e le plexo cervical (n. auricularis magnus e n. occipitalis minor) innervate le auricula.

Meato Acustic Externe

  • Illo consiste ex un portion cartilaginose e un portion ossee.
  • Glandulas ceruminose se trova in iste meato.

Cerumen

  • Le accumulation de cerumen pote provocar le reflexo vagal.

Aure Medie (Auris Media) & Membrana Tympanic (Dohártya)

  • Le membrana tympanic se considera parte del aure medie.
  • Le membrana tympanic ha structuras clave como le prominentia malleolar, plica malleolar, stria malleolar, pars flaccida, pars tensa, umbo e anello fibrocartilaginose.

Stratos del Membrana Tympanic

  • Consiste ex le stratum cutaneum, stratum radiatum, stratum circulare e stratum mucosum.
  • In conditiones normal, se pote vider un cono de lumine reflexe.
  • Conditiones pathologic include otitis acute e chronic.

Cavitate Tympanic (Dobüreg)

  • Contine le ossiculos auditores.
  • Le nervo facial se localisa in le cavitate tympanic.
  • Le cavitate ha un pariete membranacee (lateral) e un pariete labyrinthic (medial).
  • Le cochlea es adjacente al cavitate.
  • Le nervo tympanic es presente.

Muros del Cavitate Tympanic (FALAI)

  • Le muro labyrinthic (medial) es designate como muro 1.
  • Le muro tegmentale (superior) es muro 2.
  • Le muro carotic (anterior) es muro 3.
  • Le muro jugular (inferior) es muro 4.
  • Le muro mastoide (posterior) es muro 5.
  • Le muro membranacee (lateral) es muro 6.

Muro Labyrinthic

  • Presenta le fenestra vestibuli (ovale), fenestra cochleae, promontorio, prominentia del canal facial e nervo tympanic.

Muro Tegmental

  • Contine le nervo petrose major e le nervo petrose minor.

Muro Carotic

  • Contine le semicanal del musculo tensor del tympano.
  • Contine le ostium del tuba auditiva tympanic.
  • Le arteria carotis interne e canalicules caroticotympanic se trova in le muro.

Muro Jugular

  • Characterisate per le vena jugular interne, canaliculo tympanic e processo stiloideo.

Muro Mastoide

  • Illo include le antrum mastoidee, eminentia pyramidal (ubi le nervo al musculo stapedio se trova), e canaliculo del chorda tympani.
  • Mastoiditis es un condition associate.

Divisiones del Cavitate Tympanic

  • Epitympanum
  • Mesotympanum
  • Hypotympanum

Tuba Auditiva (Eustachi)

  • Connecte le aure medie al nasopharynge.
  • Illo consiste ex partes ossee e cartilaginose.
  • Ostium tympanic del tuba auditiva
  • Isthmo
  • Pars cartilaginose del tuba auditiva
  • Lamina medial e lateral
  • Canale musculotubari
  • Lamina membranacee
  • Ostium pharyngee del tuba auditiva
  • Musculo tensor veli palatini assiste in function.

Problemas con le Tuba Auditiva

  • Dysfunction del tuba de Eustachio pote resultar in differentias de pression.
  • Adenoideos enlarge pote blocar le tuba.
  • Tubos de tympanostomia (grommets) pote servir a equalar le pression.

Ossiculos del Audito (Hallócsontok)

  • Le ossiculos include le malleo, incude e stapede.

Malleo (Kalapács)

  • Illo consiste ex le capite, collo e manubrium.

Incude (Üllő)

  • Le forma de incude es simile a un sella.
  • Illo consiste ex un corpore, crus breve (fossa incudis) e crus longe.

Stapede (Kengyel)

  • Illo consiste ex un capite, crus anterior e posterior e base.
  • Se adjuta al fenestra vestibuli via le ligamento annular.

Ligamentos del Ossiculos Auditores

  • Ligamento mallei superior, ligamento incudis superior, ligamento mallei anterior, ligamento incudis posterior.

Musculos del Ossiculos Auditores

  • Le musculo stapede es innervate per le nervo facial (n. VII).
  • Le musculo tensor del tympano es innervate per le nervo trigemino (n. V).
  • Arterias que forni le ossiculos auditores include a. tympanica anterior (de a. maxillaris), rr. caroticotympanici (de a. carotis interna), a. tympanica inferior (de a. phar. asc.), a. tympanica superior (a. meningea media) e a. tympanica posterior (a. auricularis posterior).
  • Nervos includente n. tympanicus (n. IX e n. X), n. auriculotemporalis, e le plexo carotic intern.

Nervo Faciale (Nervus facialis)

  • Danio al nervo facial pote resultar in paralysi.
  • Le nervo include structuras como meato acustic interne (4), nervo petrose major (13), ganglione geniculate (5), nervo stapede (6), foramine stilo-mastoide (7) e chorda tympani (9).
