@@Home -> BiologicalLifeResearch -> BrainAreaLPC -> BrainRegionLPC_HL_AMB
This page covers biological details of component Ambiguus Nucleus. Region is part of aHuman target integrated biological model.
- Top-down path to region: Hindbrain Myelencephalon -> Myelencephalic Motor Nuclei (HL.MN) -> Expiratory Center (HL.RC) -> Ambiguus Nucleus (LPC.HL.AMB) (see Mind Maps)
- Type: nucleus
- Quality: L0
- Brain area: Lower Brain - Peripheral Control Area (LPC)
- Area circuit: Breathing and Swallowing Motor (ABS)
- Role: flexor.nucleus
- Function: Control muscles of the soft palate, pharynx, and larnyx
- Notes to function:
- On par with VGM, speech
- speech and swallowing, parasympathetic, innervates the cardiac ganglia to contribute to the control of heart rate
