Muscles of the Velopharyngeal Mechanism
Question | Answer |
---|---|
What are the Palatal Muscles? | TMPPL- (templ)1)Tensor Veli Palatini 2)Musculus Uvula 3)Palatoglossus 4)Palatopharyngeus 5)Levator Veli Palatini |
What are the Pharyngeal Muscles ? | MISSS- (Miss)1)Middle Constrictor 2)Inferior Constrictor 3)Stylopharyngeus 4)Salpingopharyngeus 5) Superior Constrictor |
2 functions: Tense & lowers palatal aponeurosis, pulls anterolateral wall of the Eustachian tube away from medial wall (opens the tube).C:inferior, winding around the hamulus, becomes tendinous and then courses medially toward center of soft palate | Function & course of Tensor Veli Palatini |
O: Medial pterygoid plate of the sphenoid and anterolateral wall of the Eustachian tube.I: Into aponeurosis and blends with fibers from other muscles | O & I for Tensor Veli Palatini |
What forms bulk of the soft palate? | Levator Veli Palatini |
C:inferior, medial and anterior F:pulls soft palate posteriorly and superiorly toward posterior pharyngeal wall | Levator Veli Palatini |
O:petrous portion of the temporal bone, medial aspect of Eustachian tube I:into soft palate blending with fibers from other side to form a sling | Levator Veli Palatini |
O:nasal spine of palatine bone I:fibers terminate near uvula | Musculus Uvula |
C:posteriorly along upper surface of soft palate toward uvula F:bulks & stiffens soft palate so that other muscles act more effectively | Musculus Uvula |
muscle found in the Anterior faucial pillar (1st palatal arch) | Palatoglossus |
O:lower surface of palatal aponeurosis, interwoven with other fibers I:sides of tongue | Palatoglossus |
C:inferior F:may pull palate down or sides of tongue up | Palatoglossus |
Muscle that lies in the Posterior faucial pillar | Palatopharyngeus |
O:lower surface of palatal aponeurosis, interwoven with other fibers I:lateral wall of pharynx and thyroid cartilage | Palatopharyngeus |
C:inferior F:draws soft palate posteriorly | Palatopharyngeus |
forms the nasopharyngeal and upper oropharyngeal walls | Superior Constrictor |
O:sides of soft palate and tongue, and in lateral pharyngeal wall I:midline pharyngeal raphe | Superior Constrictor |
C:curves posteriorly and then medially F:narrows nasopharyngeal and upper oropharyngeal space | Superior Constrictor |
O:hyoid bone I:midline pharyngeal raphe | Middle Constrictor |
C:radiates as the fibers course posteriorly F:narrows oropharyngeal space | Middle Constrictor |
O:thyroid cartilageI:midline raphe | Inferior Constrictor |
C:diverse as fibers course posteriorly and medially F:narrows laryngopharyngeal space and upper esophageal sphincter | Inferior Constrictor |
O:styloid process of the temporal bone I: fibers blend with constrictors | Stylopharyngeus |
C:down side of pharynx F:elevate and dilate pharynx | Stylopharyngeus |
O:inferior border of the medial aspect of the Eustachian tube I:fibers blend with palatopharyngeus muscles | Salpingopharyngeus |
C:downwardF:draws lateral walls of pharynx upward and medially | Salpingopharyngeus |
