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

• Top-down path to region: Peripheral Nervous System -> Parasympathetic Ganglia (PN.PSYM) -> Head and Neck Parasympathetic Ganglia (PN.PSYM.HD) -> Ciliary Ganglion (LAC.PN.PSYM.CLG) (see Mind Maps)
• Type: parasympathetic ganglion
• Brain area: Lower Brain - Autonomous Control Area
• Role: parasympathetic
• Function: Control pupillary diameter
• Notes to function: Sphincter muscles of the iris
