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

• Top-down path to region: Peripheral Nervous System -> Sympathetic Ganglia (PNS.SYM) -> Paravertebral Sympathetic Ganglia (LAC.PN.SYM.PA) -> Superior Cervical Ganglion (LAC.PN.SYM.SCG) (see Mind Maps)
• Type: sympathetic ganglion
• Brain area: Lower Brain - Autonomous Control Area
• Role: sympathetic.ganglion
• Function: Eye, tear and salivatory glands
