Samenvatting Dysfagie.
HC 1.
• Dys = moeite met

• Fagie = slikken




Slikken doen we zo’n 1000 keer per dag (speeksel). Meestal onbewust
Inname: zuigen bijv. door rietje, manipuleren = bewegen bolus in mond

Fases slikken.

• Voorbereidend orale fase Inname voedsel:
Het opnemen van vaste stoffen/vloeistof in het
lichaam en het manipuleren van deze stoffen
in de mond.
- Zuigen
- Afhappen
- Kauwen
- Manipuleren voedsel
- Speekselvorming
Willekeurige fase, bewuste handelingen (ook al
denk je er niet steeds over na)
• Orale transportfase Naar achteren brengen bolus:
• Kauwen stopt
• Verplaatsen bolus naar achteren
• Slikinzet
Willekeurige fase; verplaatsen gaat bewust,
inzet van de slik meestal onbewust, maar wel
tegen te houden.
• Faryngeale fase Passage bolus door keelholte (farynx):
 Activatie slikreflex

 Sluiten stemplooien
 Sluiten epiglottis

,  Bolus verplaatst door farynx
 Openen UES
 Ontspanning spier
 Heffing/kanteling larynx, (hierdoor gaat
de epiglottis over de trachea)

Reflexmatige fase, niet te sturen, gebeurt
gewoon.

slokdarmsfincter
