Components

(generated)


  • Component items*:
  • *Ear sound sensory data* (*ear-sensory-sound-data*)
* Ear - inner hair cells (ear-inner-hair-cells -> LPC.PN.SG.SP): frequency-aligned tonotopic mapping
* Ear - outer hair cells feedback (ear-outer-hair-cells-feedback -> LPC.PN.SG.SP): verifies amplify actions done
* Ear - somatic receptors (ear-somatic -> LPC.PN.SG.GNG): from skin to geniculate ganglion to spinal trigeminal nucleus
* Ear - outer ear skin (ear-external-skin -> LPC.PN.SG.UDRG): skin over the mastoid process, back of the auricle, lobule and a portion of the scalp
* Ear - acoustic meatus skin (ear-acoustic-meatus-skin -> LPC.PN.SG.TRG): from skin lining external acoustic meatus, and tympanic membrane to trigeminal gangion
* Ear - visceral receptors (ear-visceral -> LPC.PN.SG.JUG): pain, temperature, and touch
* Ear - timpanic cavity (ear-timpanic-cavity -> LPC.PN.SG.PET): pain, temperature, and touch
  • *Ear vestibular sensory data* (*ear-sensory-vestibular-data*)
* Ear - semicircular canals, cristae (ear-semicircular-canals -> LPC.PN.SG.CVB): activate afferent receptors in response to rotational acceleration
* Ear - utricle, maculae (ear-utricle -> LPC.PN.SG.UVB): activate afferent receptors in response to horizontal linear acceleration
* Ear - saccule, maculae (ear-saccule -> LPC.PN.SG.SVB): activate afferent receptors in response to vertical linear acceleration
  • *Ear sound sensory control* (*ear-sensory-control*)
* [- outer hair cells] (BrainRegionLPC_MM_SOC LPC.MM.SOC -> HumanMusclesHead ear-outer-hair-cells): contracts basilar membrane; mechanically amplify low-level sound that enters cochlea
* [- stapedius muscle] (BrainRegionLPC_HP_FCM LPC.HP.FCM -> HumanMusclesHead ear-stapedius): dampens vibrations of stapes
* [- tympanic membrane muscle] (BrainRegionLPC_HP_PTP_TRM LPC.HP.PTP.TRM -> HumanMusclesHead ear-tensor-tympani-muscle): dampen sounds, such as those produced from chewing
  • *Ear move muscles* (*ear-move*)
* [- anterior auricular muscle] (BrainRegionLPC_HP_FCM LPC.HP.FCM -> HumanMusclesHead ear-anterior-auricular-muscle): pulls ear forward
* [- posterior auricular muscle] (BrainRegionLPC_HP_FCM LPC.HP.FCM -> HumanMusclesHead ear-posterior-auricular-muscle): pulls ear backward
* [- superior auricular muscle] (BrainRegionLPC_HP_FCM LPC.HP.FCM -> HumanMusclesHead ear-superior-auricular-muscle): pulls ear upward
* [- oblique muscle of auricle] (BrainRegionLPC_HP_FCM LPC.HP.FCM -> HumanMusclesHead ear-oblique-auricular-muscle): movement of the ears
* [- temporoparietalis muscle] (BrainRegionLPC_HP_FCM LPC.HP.FCM -> HumanMusclesHead ear-temporoparietalis-muscle): assist the frontal belly in drawing the epicranial aponeurosis towards the front of the cranium
