Lesson 3 Anatomy

  1. primary function: protects the airway from foreign objects
  2. Secondary Function: Allows for holding breath, heavy lifting, phonation, and childbirth
  3. Vibration of the vocal folds which produces speech voicing
  4. the energy that allows for phonation /v/ vs /f/
  5. paired band of tissue housed within the larynx. vibrating component of the larynx to produce sound
    vocal folds
  6. the process of bringing the vocal folds together for phonation
  7. the process of drawing the vocal folds apart to terminate phonation
  8. given a constant volume flow of air or fluid, at a point of constriction there will be a decrease in air pressure and an increase in velocity of the flow. example: garden hose
    bernoulli principle
  9. comprised of three paired cartilages and three unimpaired
  10. sits on top of trachea contains the arch which is a low narrow portion in front, and the posterior quatrate lamina which is the wide thick portion in back
    cricoid cartilage
  11. Cricoid Cartilage: provides clearance for vocal folds
  12. Cricoid Cartilage: Provides point of articulation for arytenoid cartilages
    Posterior Quadrate Lamina
  13. Articulates inferiorly with the cricoid cartilage. Largest laryngeal cartilage
    Thyroid Cartilage
  14. Part of Thyroid Cartilage: Two plates of cartilage that make up the anterior surface
    Thyroid Laminae
  15. Part of the Thyroid Cartilage: horns located on the posterior aspect of the thyroid cartilage
    Inferior and Superior Cornua
  16. Part of the Thyroid Cartilage: Where the thyroid laminae join
    Thyroid angle
  17. Part of the thyroid cartilage: superior most point of the thyroid angle
    Thyroid notch
  18. Part of the thyroid cartilage: lateral superficial aspect of the thyroid laminae
    oblique line
  19. Part of the thyroid cartilage: project downward to articulate with cricoid cartilage
    inferior cornua
  20. Part of the thyroid cartilage: project upward to articulate with hyoid bone
    superior cornua
  21. Arytenoid Cartilages: Paired cartilage that articulates with the lamina of the cricoid cartilage.
    -Forms posterior point of attachment for vocal folds
    -Allows for onset and offset of voicing
    -Pyramidal shape
    Arytenoid Cartilages
  22. Arytenoid Landmarks (All Bare Vaginas are Merry)
    • -Apex
    • -Base
    • -Vocal Process
    • -Muscular Process
  23. Arytenoid Cartilages: superior portion of the arytenoid
  24. Arytenoid Cartilages: inferior portion that articulates with the cricoid
  25. Arytenoid Cartilages: project toward thyroid notch (vocal fold attachment)
    vocal process
  26. Arytenoid Cartilages: lateral portion of the arytenoid (attachment for muscles that adduct and abduct the vocal folds)
    Muscular process
  27. _____ Cartilages: Paired cartilage that rides on the superior surface of each arytenoid
    Corniculate Cartilages
  28. -Unpaired leaf shaped cartilage
    -Arises from the inner surface of the angle of the thyroid cartilage just below the notch
    -Attaches to the thyroid via the thyroepiglottic ligament
    -Sides of epiglottis joined the arytenoid cartilage via the aryepiglottic folds
  29. -Folds over to protect the airway
    -Food passes over the epiglottis and into the esophagus
  30. Epiglottis: the Valleculae and Pyriform Sinuses make up the
    Pharyngeal Recesses
  31. Epiglottis: Pair of small indentations between the root of the tongue and epiglottis. Important landmark in determining swallowing deficits
  32. Epiglottis: Small fossae (indentations) between aryepiglottic folds medially and the mucous lining of the thyroid cartilage
    pyriform sinuses
  33. During a normal swallow, the ____ elevates while the epiglottis folds down to prevent food or liquid from entering the airway
  34. _____ "little valleys" lie on either side of the base of the epiglottis
  35. When ____ is compromised the larynx may not elevate properly and food or liquid accumulates in the _____
    swallowing, valleculae
  36. -Small, paired, cartilages embedded in aryepiglottic folds
    -Cause a small bulge on the surface of the membrane
    -Provides support for membranous laryngeal covering
    cuniform cartilages
  37. -Unpaired bone
    -Articulates with the superior cornu of the thyroid cartilage 
    -Only bone of the body that isn't attached to another bone
    hyoid bone
  38. Hyoid Bone: point of attachment for six muscles
  39. Hyoid Bone: Lateral surface of corpus and projects posteriorly
    Greater Cornu
  40. Hyoid Bone: Junction of the corpus and greater cornu
    Lesser Cornu
  41. The oral cavity is sealed off from the trachea and lower respiratory passageways. Not able to produce sound. Put in place to allow for breathing
    Laryngectomy or removal of the larynx
