Components

(generated)

Component items:

• Speaker sensory data (speaker-sensory-data)
  • Speaker - palatine tonsil receptors (palatine-tonsil-receptors -> LPC.PN.SG.JUG): visceral mucous membrane over soft palate and tonsil
• Speaker phonatory muscles (speaker-phonatory-muscles): move vocal cords together and serve production of voice
  • [- lateral cricoarytenoid muscle] (LAC.PN.PSYM.ILG -> lateral-cricoarytenoid-muscle): adduct and medially rotate the cartilage, pulling the vocal ligaments towards the midline and backwards and so closing off the rima glottidis
  • [- arytenoid muscle] (LPC.HM.AMB -> arytenoid-muscle): approximate the arytenoid cartilages (close rima glottidis)
  • [- cricothyroid muscle] (LPC.HM.AMB -> cricothyroid-muscle): tension and elongation of the vocal folds (has minor adductory effect)
  • [- thyroarytenoid muscle] (LAC.PN.PSYM.ILG -> thyroarytenoid-muscle): thickens the vocal folds and decreases length; also helps to adduct the vocal folds during speech
  • [- oblique arytenoid muscle] (LAC.PN.PSYM.ILG -> oblique-arytenoid-muscle): sphincter of the laryngeal inlet
  • [- posterior cricoarytenoid muscle] (LAC.PN.PSYM.ILG -> posterior-cricoarytenoid-muscle): abducts and laterally rotates the cartilage, pulling the vocal ligaments away from the midline and forward and so opening the rima glottidis
  • [- thyroepiglottic muscle] (LAC.PN.PSYM.ILG -> thyroepiglottic-muscle): closes the inlet to the larynx
  • [- aryepiglottic muscle] (LAC.PN.PSYM.ILG -> aryepiglottic-muscle): close the inlet
• Speaker respiratory larynx muscles (speaker-respiratory-muscles): move vocal cords apart and serve breathing
  • [- thyrohyoid muscle] (LPC.SC.VH.VM -> larynx-thyrohyoid-muscle): depresses the hyoid and elevates the larynx
  • [- omohyoid muscle] (LPC.SC.VH.VM -> omohyoid-muscle): depresses the larynx and hyoid bone; carries hyoid bone backward and to the side
  • [- palatopharyngeus muscle] (LPC.HM.AMB -> palatopharyngeus-muscle): pulls pharynx and larynx
  • [- sternohyoid muscle] (LPC.SC.VH.VM -> sternohyoid-muscle): depress hyoid bone
  • [- sternothyroid muscle] (LPC.SC.VH.VM -> sternothyroid-muscle): elevates larynx, may slightly depress hyoid bone
  • [- levator muscle of thyroid gland] (LPC.HM.AMB -> thyroid-gland-levator-muscle): elevates the thyroid gland
