  • What muscles are a part of the suprahyoid muscles?
    Digastric, Stylohoid, Mylohoid, Geniohyoid, Genioglossus, Hyoglossus, Styloglossus
  • What does the inferior constrictor do? What does it include?
    Constricts walls of the pharynx during swallowing. It includes the cricopharyngeus which is the PES muscle.
  • What does the lateral pterygoid do?
    Protracts mandible, depresses chin, contributes to lateral chewing movements
  • What is the first part of the pharyngeal stage of a typical swallow?
    The pharyngeal wall moves forward.
  • What does the medial pterygoid do?
    Elevates mandible, protrudes mandible, contribute to smaller grinding movements
  • What does the levator veli palatini do?
    Elevates soft palate during yawning and swallowing
  • What do the intrinsic muscles of the tongue do?
    The intrinsic muscles of the tongue help to shape, contour, and can change the function of the tongue. They are used for the oral prep stage.
  • What does the digastric muscle do?
    Depresses the mandible, elevates and steadies hyoid during swallowing
  • What are the muscles of the lower face?
    Orbicularis oris, Buccinator, Mentalis
  • What does the temporal muscle do?
    Elevates mandible to close jaw
  • What does the cricothyroid do?
    Stretches and tenses vocal ligament
  • What is the first part of the oral stage?
    The tongue moves the bolus from the anterior to the posterior part of the oral cavity.
  • What does the mentalis do?
    Raises the central portion of the lips
  • What happens during the pharyngo-esophageal stage?
    The PES relaxes during the passage of the bolus from the pharynx to the esophagus.
  • What does the stylohoid muscle do?
    Elevates and retracts hyoid and elongates FOM
  • What does the superior constrictor do?
    Constricts walls of the pharynx during swallowing.
  • What does the posterior cricoarytenoid do?
    ABducts vocal folds
  • What is the second part of the pharyngeal stage?
    The soft palate/velum elevates to close off the nasopharynx.
  • What does the thyroartenoid do?
    Relaxes vocal ligament
  • What does the orbicularis oris do?
    ADDucts the lips, sealing off oral cavity
  • What does the genioglossus do?
    Protrudes tongue, wags tongue to opposite side
  • What are the pharyngeal muscles?
    Superior constrictor, middle constrictor, and inferior constrictor
  • What is the fifth part of the pharyngeal stage?
    The larynx elevates
  • What does the mylohyoid do?
    Elevate hyoid, FOM, and tongue during swallowing
  • What does the masseter do?
    Elevates mandible to close jaw, slightly protrude jaw
  • What is the third part of the pharyngeal stage?
    Pharyngeal contraction/stripping wave occurs moving the bolus through the pharynx.
  • What does the palatoglossus do?
    Elevates posterior tongue, depresses soft palate, constricts faucial pillars
  • What does the middle constrictor do?
    Constricts walls of the pharynx during swallowing.
  • What does the geniohyoid do?
    Pulls hyoid antero-superiorly, shortens FOM, widens pharynx
  • What is the fourth part of the pharyngeal stage?
    The hyoid bone moves superiorly and anteriorly.
  • What does the styloglossus do?
    Retracts and curls sides of tongue, contributing to tongue grooving
  • What are the muscles of mastication?
    Temporal, Masseter, Lateral pterygoid, Medial pterygoid
  • What is the oral preparatory stage of a typical swallow?
    The food is masticated and mixed with saliva to form a bolus
  • What does the tensor veli palatini do?
    Tenses soft palate, opens tympanic tube during yawning and swallowing
  • What does the palatopharyngeus do?
    Contracts pharyngeal wall, tense soft palate
  • What does the buccinator do?
    Draws lips against teeth
  • What is the seventh part of the pharyngeal stage?
    The epiglottis inverts to close off the laryngeal vestibule.
  • What are the intrinsic laryngeal muscles?
    Cricothyroid, Thryoarytenoid, Posterior Cricoarytenoid, Lateral Cricoarytenoid, Interarytenoids
  • What does the lateral cricoarytenoid do?
    ADDucts vocal folds
  • What is the second part of the oral stage of a typical swallow?
    Posterior retraction of the tongue occurs.
  • What does the interarytenoids do?
    ADDucts arytenoid cartilages, closes glottis
  • What happens during the esophageal stage of a typical swallow?
    The bolus moves to the stomach by the peristaltic movement of the esophagus.
  • What are the muscles of the palate?
    Levator veli palatini, Palatopharyngeus, Palatoglossus, Tensor veli palatini
  • What does the hyoglossus do?
    Depresses tongue to midsection, leading to gonue grooving
  • What is the sixth part of the pharyngeal stage?
    The vocal folds adduct.
