This page covers biological details of component Geniculate 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) -> Geniculate Ganglion (LPC.PN.SG.GNG) (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: Trophic support for survival
• Notes to function:
  • Innervation taste buds, ear skin
