This page covers biological details of component Sacral Parasympathetic Nucleus. Region is part of aHuman target integrated biological model.

• Top-down path to region: Spinal Cord -> Intermediate Zone (SC.IZ) -> Lamina VII (SC.IZ.L7) -> Intermediolateral Column (AVA.SC.IZ.IMLC) -> Sacral Parasympathetic Nucleus (LAC.SC.IZ.SPS) (see Mind Maps)
• Type: nucleus
• Brain area: Lower Brain - Autonomous Control Area
• Role: parasympathetic
• Function: parasympathetic impulses pass via postganglionic fibers to the urinary bladder, erectile tissues, and the smooth muscles and glands in the colon and rectum
• Notes to function: from Lamina VII, visceral parasympathetic
