Petrosal Ganglion

@@Home -> BiologicalLifeResearch -> BrainAreaLPC -> BrainRegionLPC_PN_SG_PET


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) -> Sensory Interoception Ganglia (PN.SG.SI) -> Petrosal Ganglion (LPC.PN.SG.PET) (see Mind Maps)
  • Type: sensory ganglion
  • Quality: L0
  • Brain area: 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
