'''Component items''':
* '''Speaker sensory data''' ('''speaker-sensory-data''')
** Speaker - palatine tonsil receptors (palatine-tonsil-receptors -> [[BrainRegionLPC_PN_SG_JUG|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
** [http://en.wikipedia.org/wiki/Lateral_cricoarytenoid_muscle Speaker - 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
** [http://en.wikipedia.org/wiki/Arytenoid_muscle Speaker - arytenoid muscle] ([[BrainRegionLPC_HM_AMB|LPC.HM.AMB]] -> [[HumanMusclesNeck|arytenoid-muscle]]): approximate the arytenoid cartilages (close rima glottidis)
** [http://en.wikipedia.org/wiki/Cricothyroid_muscle Speaker - cricothyroid muscle] ([[BrainRegionLPC_HM_AMB|LPC.HM.AMB]] -> [[HumanMusclesNeck|cricothyroid-muscle]]): tension and elongation of the vocal folds (has minor adductory effect)
** [http://en.wikipedia.org/wiki/Thyroarytenoid_muscle Speaker - 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
** [http://en.wikipedia.org/wiki/Oblique_arytenoid Speaker - oblique arytenoid muscle] ([[BrainRegionLAC_PN_PSYM_ILG|LAC.PN.PSYM.ILG]] -> [[HumanMusclesNeck|oblique-arytenoid-muscle]]): sphincter of the laryngeal inlet
** [http://en.wikipedia.org/wiki/Posterior_cricoarytenoid_muscle Speaker - 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
** [http://en.wikipedia.org/wiki/Thyroepiglottic_muscle Speaker - thyroepiglottic muscle] ([[BrainRegionLAC_PN_PSYM_ILG|LAC.PN.PSYM.ILG]] -> [[HumanMusclesNeck|thyroepiglottic-muscle]]): closes the inlet to the larynx
** [http://en.wikipedia.org/wiki/Aryepiglottic_muscle Speaker - 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
** [http://en.wikipedia.org/wiki/Thyrohyoid_muscle Speaker - thyrohyoid muscle] ([[BrainRegionLPC_SC_VH_VM|LPC.SC.VH.VM]] -> [[HumanMusclesNeck|larynx-thyrohyoid-muscle]]): depresses the hyoid and elevates the larynx
** [http://en.wikipedia.org/wiki/Omohyoid_muscle Speaker - 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
** [http://en.wikipedia.org/wiki/Palatopharyngeus_muscle Speaker - palatopharyngeus muscle] ([[BrainRegionLPC_HM_AMB|LPC.HM.AMB]] -> [[HumanMusclesHead|palatopharyngeus-muscle]]): pulls pharynx and larynx
** [http://en.wikipedia.org/wiki/Sternohyoid_muscle Speaker - sternohyoid muscle] ([[BrainRegionLPC_SC_VH_VM|LPC.SC.VH.VM]] -> [[HumanMusclesNeck|sternohyoid-muscle]]): depress hyoid bone
** [http://en.wikipedia.org/wiki/Sternothyroid_muscle Speaker - sternothyroid muscle] ([[BrainRegionLPC_SC_VH_VM|LPC.SC.VH.VM]] -> [[HumanMusclesNeck|sternothyroid-muscle]]): elevates larynx, may slightly depress hyoid bone
** [http://en.wikipedia.org/wiki/Levator_muscle_of_thyroid_gland Speaker - levator muscle of thyroid gland] ([[BrainRegionLPC_HM_AMB|LPC.HM.AMB]] -> [[HumanMusclesNeck|thyroid-gland-levator-muscle]]): elevates the thyroid gland
