This page covers biological details of component Petrosal Ganglion.
Region is part of aHuman target integrated biological model.

  * *Top-down path to region*: Peripheral Nervous System -> Sensory Ganglia (PNS.SG) -> [BrainCenterPN_SG_SI Sensory Interoception Ganglia] (PN.SG.SI) -> [BrainRegionLPC_PN_SG_PET Petrosal Ganglion] (LPC.PN.SG.PET) (see [OverallMindMaps Mind Maps])
  * *Type*: sensory ganglion
  * *Quality*: L0
  * *Brain area*: [BrainAreaLPC Lower Brain - Peripheral Control Area] (LPC)
  * *Area circuit*: Taste Senses (STS)
  * *Role*: sensory.ganglion
  * *Function*: Integration of afferent signaling from viscera
  * *Comments*: CN IX, superior and inferior ganglia of glossopharyngeal nerve, Hering's nerve
  * *Notes to function*: 
   * mucous membranes of pharynx, middle ear, carotid body and sinus, taste sensor on the posterior third of tongue to SOL
