  12. Vomit Reflex
    • Induced By: Noxious odors, tasts, gastrointestinal discomfort, and vestibular dysfunction.
    • Cause: Vocal folds adduct, abdominal muscles contract violently, the UES and LES relax, the larynx, velu, and pharynx elevate, the epiglottis closes over the aditus laryngis, and the tongue protrudes.
  13. Cough Reflex
    • Induced By: Noxious stimulition of the pharynx, larynx, trachea, or bronchi.
    • Cause: The true and false vocal folds adduct and the abdominal muscles contract building up subglottal pressure for forced exhalation.

  36. Adnoids/Pharyngeal Tonsils
    Become larger as we get older, then begin to shrink again as we reach puberty.
  37. Velopharyngeal Closure
    Soft palate meeting the posterior laryngeal wall. Creates a closure and prevents food/drink from entering the nasal cavity.
  38. Palatine tonsils AKA?
    The normal tonsils
  39. Palatine Tonsils

  42. Cecum
    Hidden Foraman
  43. Vellecula
    Hole or pocket. Important landmark with patients with dysphagia. Formed by the back of the tongue and the epiglottis.
  44. 3 Parts of the Pharynx
    Nasopharynx, Oralpharynx, and the laryngealpharynx
  45. Cricoid Cartilage
    Gets wider posterialy. Like a sigment ring. Forms a complete circle. Sits above the trachea.
  46. Throid Carilage
    • Largest cartilage.
    • Forms protection to the true and false vocal folds
  47. False Vocal Folds
    Ventricular folds
  48. What is the difference between a child and adult larynx?
    In a child, the oral cavity is smaller, the larynx is elevated, which makes it higher in the neck. It lowers in the first 4 years of life. This allows the velum to lock into the valleculie during swallowing.
  49. Glottis
    The variable space between the true vocal folds
  50. Digastric Muscle

  53. Pars Vocalis
    Membranous.Contributes to phonation. Vocal Part. Anterior 2/3rds.
  54. Pars Respiratus
    Cartilagenous. Contributes to breathing. Breathing part. Posterior 1/3rds
  55. Reflexes
    Found mainly in or around the oral cavity and help newborn babies thrive and survive.
  56. Control of Reflexes
    Gradually, through normal development, a child will gain voluntary control over reflexes. Cerebralpalsy children have a hard time gaining control over their reflexes.
  57. Larygneal Prominence
    Adams Apple.
  58. Ways we use our larynx
    Protection from aspiration. Phonation. Articulation. Swallowing. Coughing. Lifting. Pulling. Pushing. Bearing down. Child birth. Vomiting. Retching. Clearing the throat. Respiration. Yawning. Laughing. Resonating. Whispering. Hiccuping. Sneezing. Gaging.
  59. How does the Larynx provide protection from aspiration?
    The Epiglottis closes over the aditus laryngeous and the true and false vocal folds tightly close.
  60. Locking the Larynx AKA?
    Abdominal Fixation
  61. Corniculate and Cuneiform Tubercles
    Cover the Corniculate and Cuneiform Cartilages.

    • (Lateral concae thyroid vacet)
  66. Lateral Cricoarytenoid Muscle
    Antagonist to the Posterior Cricoarytenoid Muscle. Adductor of anterior 2/3rds of the vocal folds, (the pars vocalis, membranous part.)

    • Laryngeal Membrane.
    • Courses up and contributes to the vocal ligament.
    • Superior margin becomes the vocal ligament.

    • Epithelium
    • Superficial Layer of Lamina Propria
    • Intermediate Layer of Lamina Propria
    • Deep Layer of Lamina Propria
    • Thyroarytenoid M.
  71. Cover of the True Vocal Folds = Mucous membrane or Mucosa
    • Epithelium
    • Superficial Layer of Lamina Propria

    • Intermediate Layer of Lamina Propria
    • Deep Layer of Lamina Propria
  73. Body
