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

• Top-down path to region: Peripheral Nervous System -> Sensory Ganglia (PNS.SG) -> Sensory Exteroception Ganglia (PN.SG.SE) -> Trigeminal Ganglion (LPC.PN.SG.TRG) (see Mind Maps)
• Type: sensory ganglion
• Quality: L0
• Brain area: Lower Brain - Peripheral Control Area (LPC)
• Area circuit: Sensory Face (SF)
• Role: sensory.ganglion
• Function: Integration of external auditory meatus (auricular branch), cranial meninges (meningeal branch), and external surface of tympanic membrane
• Comments: Gasserian, semilunar
• Notes to function:
  • sensory fibers of ophthalmic, maxillary, mandibular nerves to principal trigeminal nucleus
