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
