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

• Top-down path to region: Hindbrain Myelencephalon -> Myelencephalic Parasympathetic Nuclei (HL.PSN) -> Salivatory Nucleus (LAC.HL.SAL) -> Superior Salivatory Nucleus (LAC.HL.SAL.SSL) (see Mind Maps)
• Type: nucleus
• Brain area: Lower Brain - Autonomous Control Area
• Role: parasympathetic
• Function: facilitate respiration - produce thiker saliva
• Notes to function: preganglionic parasympathetic nucleus; project to submaxillary (submandibular) ganglion to submandibular/sublingual salivatory glands; to sphenopalatine ganglion to superior maxillary nerve as vasodilator and secretory fibers to the mucous membrane of the nose, soft palate, tonsils, uvula, roof of the mouth, upper lips and gums, parotid and orbital glands; facial nerve
