Figure 6From: Resuscitation and auto resuscitation by airway reflexes in animalsReflex arch and mechanisms of AspR, ExpR and CR and their voluntarycounterparts. Schematic illustration of the reflex arch and mechanismsof AspR, ExpR and CR and their voluntary counterparts. A- afferent roots: viatrigeminal nerve from the upper part of nasal cavity for sniffing, via n.glosso-pharyngicus from the nasopharynx for AspR, via n. laryngicus sup. fromthe larynx for ExpR and via n. vagus from tracheal-bronchial region andproprioceptive afferents for CR. E- efferent roots: to inspiratory muscles(diaphragm and external intercostals) and to expiratory muscles (abdominal andinternal intercostals) for ExpR and CR. C- central structures: “Generatorfor inspiration” in pre-Bötzinger complex for AspR, “generatorfor expiration” in NSRF- nucleus sub-retro-facialis for ExpR, and bothgenerators for CR. Breathing manoeuvres allow voluntary performance of allthree reflexes (voluntary sniffs, prompt expiration and sniff followed bystrong expiration), reproduced with permission from our review [40].Back to article page
