  1. Lingua (dupaPapilian II) prezentare de Lupu Adrian

  2. Cevomstudia ? • Conformatieexterna • Radacina • Corpul • Structura (schelet, muschiextr/intr, mucoasa) • Irigatie, inervatie Limba = organ conic, musculo-membranos.

  3. Conformatieexterna • Segmente: • corp………………….(orizontal) • → “sant terminal” V cu “gauraoarba” in varf • radacina …………..(vertical)

  4. Radacinalimbii • 2 fete • 2 margini • 2 extremitati • segment faringian • leagacorpul de: mandibula + hioid • plici + valeculeglosoepiglotice • (tractiunelimba - epiglota)

  5. Corpullimbii • 2 fete • 2 margini • varf • baza • segment bucal • Fata inferioara • fraullimbii • se observavascularizatiavenoasa • Fata dorsala / superioara • sant median • aspectuleste important la examenul clinic • Marginile • in contact cu dintii (-> posibileulceratii) • Varful • sant vertical (continuitatesant sup si inf) • Baza • continuitatespreradacina

  6. Structura • Scheletulosteo - fibros • Membranahioglosiana • patrat • plan frontal • oshioid – sant terminal • oshioid • membranahioglosiana • septul lingual • aponevrozalimbii • Septullimbii • coasa • plan medio-sagital • intre mm genioglosi Aponevrozalimbii - ingrosaremucoasalinguala din regiuneadorsala (ins ptunii m)

  7. Muschii • intrinseci = insertieambelecapetein intlimbii, peseptsauaponevroza…….forma • extrinseci = originea “innafara” limbii……………………………………………..deplasare • Muschiiextrinseci(4+2 m) • M. Genioglos • insertii: tubercul sup spinamentala -> strabatelimbavarf - hioid • actiune: limba (aplicalimbapeplanseubucal) si hioid • Dupacontractie: • bilaterala: aplicalimbapeplanseubucal • unilaterala: f. ant – vflimba in jos si inapoi • f. mijl – traglimba in afaragurii • f. post – duclimba si hioidinainte • raporturi: fata lat = perete medial lojasublinguala

  11. Mucoasa (prezintapapile, glande si foliculi) • continuitate cu mucoasabuco– faringiana • traseumucoase: • se ridica de peplanseulbucal -> fraullimbii • acoplimba, apoi -> pliciglosoepiglotice • Culoare: • alb-roz…….. f. dorsala • rosu…………..mg • roz……………..inf • Consistenta: • groasa + aderenta m.………... f. dorsala • redusa……………………………....mg • aproapetransparenta………..inf
