This page covers biological details of component Retroambigualis 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) -> Retroambigualis Nucleus (LRC.HL.RA) (see Mind Maps)
  • Type: nucleus
  • Quality: L0
  • Brain area: Lower Brain - Motor Reflex Area (LRC)
  • Area circuit: Breathing and Swallowing Reflexes (LRB)
  • Role: subcortical.motor.flexor
  • Function: Groups of premotor interneurons producing detailed motor actions
  • Notes to function:
    • Different combination of activation of these premotor neurons determines vocalization, vomiting, coughing, sneezing, mating posture, or child delivery
    • ventral respiratory group
