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] (BrainRegionLAC_PN_PSYM_ILG LAC.PN.PSYM.ILG -> HumanMusclesNeck 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] (BrainRegionLPC_HM_AMB LPC.HM.AMB -> HumanMusclesNeck arytenoid-muscle): approximate the arytenoid cartilages (close rima glottidis)
* [- cricothyroid muscle] (BrainRegionLPC_HM_AMB LPC.HM.AMB -> HumanMusclesNeck cricothyroid-muscle): tension and elongation of the vocal folds (has minor adductory effect)
* [- thyroarytenoid muscle] (BrainRegionLAC_PN_PSYM_ILG LAC.PN.PSYM.ILG -> HumanMusclesNeck thyroarytenoid-muscle): thickens the vocal folds and decreases length; also helps to adduct the vocal folds during speech
* [- oblique arytenoid muscle] (BrainRegionLAC_PN_PSYM_ILG LAC.PN.PSYM.ILG -> HumanMusclesNeck oblique-arytenoid-muscle): sphincter of the laryngeal inlet
* [- posterior cricoarytenoid muscle] (BrainRegionLAC_PN_PSYM_ILG LAC.PN.PSYM.ILG -> HumanMusclesNeck 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] (BrainRegionLAC_PN_PSYM_ILG LAC.PN.PSYM.ILG -> HumanMusclesNeck thyroepiglottic-muscle): closes the inlet to the larynx
* [- aryepiglottic muscle] (BrainRegionLAC_PN_PSYM_ILG LAC.PN.PSYM.ILG -> HumanMusclesNeck aryepiglottic-muscle): close the inlet

• *Speaker respiratory larynx muscles* (*speaker-respiratory-muscles*): move vocal cords apart and serve breathing

* [- thyrohyoid muscle] (BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM -> HumanMusclesNeck larynx-thyrohyoid-muscle): depresses the hyoid and elevates the larynx
* [- omohyoid muscle] (BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM -> HumanMusclesNeck omohyoid-muscle): depresses the larynx and hyoid bone; carries hyoid bone backward and to the side
* [- palatopharyngeus muscle] (BrainRegionLPC_HM_AMB LPC.HM.AMB -> HumanMusclesHead palatopharyngeus-muscle): pulls pharynx and larynx
* [- sternohyoid muscle] (BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM -> HumanMusclesNeck sternohyoid-muscle): depress hyoid bone
* [- sternothyroid muscle] (BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM -> HumanMusclesNeck sternothyroid-muscle): elevates larynx, may slightly depress hyoid bone
* [- levator muscle of thyroid gland] (BrainRegionLPC_HM_AMB LPC.HM.AMB -> HumanMusclesNeck thyroid-gland-levator-muscle): elevates the thyroid gland
