This page covers biological details of component Inferior 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) -> Inferior Salivatory Nucleus (LAC.HL.SAL.ISL) (see Mind Maps)
• Type: nucleus
• Quality: L0
• Brain area: Lower Brain - Autonomous Control Area (LAC)
• Area circuit: Salivation and Tears Control (LAS)
• Role: parasympathetic.nucleus
• Function: facilitate digestion - produce watery saliva
• Notes to function:
  • preganglionic parasympathetic nucleus
  • project to otic ganglion to parotid and lingual (von Ebner) salivatory glands
  • posterior pulmonary plexus - motor fibers are derived from inferior salivatory nucleus
  • glossopharyngeal nerve
