Swallowing Definitions

  1. Lips
    • Orbicularis oris and soft tissue
    • Full and interactive in newborn with "posturing" around the nipple
    • Keeps food within the mouth. Allow changes in intra-oral pressure
  2. Cheeks
    Buccinator and masseter and soft tissue
  3. Tongue
    Attachments to mandible, hyoid bone, styloid process of tghe cranium and pharynx. Fills the oral cavity. Together with soft palate and epiglottis creates a posterior seal. Tongue is mobile component in oral cavity but does mostly anterior to posterior movement
  4. Hard palate
    Palatine process of the maxilla and palatine bone
  5. Soft palate/ velum and uvula
    • soft tissue that is a continuation of hard palate.
    • Approximates with the epiglottis and nearly lays on the back of the tongue creating a posterior seal. Located between the oral cavity and pharynx and helps keep the bouls within the mouth. Develops intra-oral pressure
  6. Pharynx
    • a common passage way for the respiratory, digestive, and vocal passageway
    • dual passage way = swallowing and pharyngeal patency for respiratory
  7. Nasopharynx
    Nasal choanae and elevated soft palate
  8. Oropharynx
    Between elevated soft palate and epiglottis. Includes epiglottis and valleculae
  9. Hypopharynx
    From base of epiglottis to UES. Includes piriform sinuses. Valve between oropharynx and nasapharynx - keeps food out of nose. Seals oral cavity
  10. Hyoid bone
    • up and under base on tongue, free floating bone, by muscle attachments.
    • Muscle stabilized by suprahyoid and infrahyoid muscles
  11. Valecular space
    is the space/depression formed between the base of the tongue and the epiglottis. Has two sides or pockets. In infants "bolus accumulation site" Level of 4th cervical vertebrae.
  12. Pyriform sinuses
    bilateral pockets/depression located in the pharynx below the inlet to larynx. They are formed by the shape of the muscle fibers of the inferior pharyngeal constrictor where they attach to the thyroid cartilage/pharyngeal walls. end inferiorly at the criopharyngeus muscle
  13. Larynx
    Gateway to the trachea. Connects lower part of the pharynx with the trachea. Has attachments to hyoid bone and cervical vertebrae. Includes epiglottis, true and false vocal cords and arytenoids. Primarily cartilaninous structure.

    Major function: Protection of the lower airways. Respiratory Phonation
  14. Arytenoid cartilages
    • on top of the larynx
    • help stabilize the top of the larynx but are very mobile
  15. Aryepiglottic folds
    • form the lateral sides of the larynx
    • terminate in the false vocal cords
  16. Laryngeal vestibule
    • entrance into the airway/inlet into
    • is bounded by the epiglottis anteriorly, the aryepiglottic folds laterally, and the arytenoids cartilages posteriorly
  17. Larengeal ventricle
    area between the false and true vocal cords
  18. Supraglottic space
    area above the vocal cords
  19. Epiglottis
    the topmost surface of the larynx. Seals airway: Folds against aryepiglottic folds. Rides higher in the infant
  20. Trachea
    Windpipe - semi circular tube composed of cartilaginous rings and associated soft tissue. Trachea and esophagus share common wall until trachea bifurcates
  21. Upper esophageal sphincter
    • must relax to allow the bolus to enter the esophagus
    • normally closed to prevent the reflux of food previously swallowed from re-entering the pharynx and to keep air out of the digestive system during respirations
    • Develops pressure within pharynx
  22. Esophagus
    • thin muscular tube that distends as food boluses are proplled through it by peristaltic movements
    • passes through the diaphragm and terminates in the stomach
    • begins at the upper esophageal sphincter and ends at the lower esophageal sphincter
