Coordination of the deglutition and respiration. Swallowing respiration.

Coordination of respiration and swallowing: functional pattern and relevance of vocal folds closure.

CONTEXT Breathing and swallowing coordination, despite the expressive number of study, remain as theme deserving further research. OBJECTIVE To identify a coordination pattern between swallowing and the natural breathing pause that occur in association with it (swallowing apnea) and also the relevance of the vocal folds closure in this process. METHODS Sixty-six adults, male and female, inc...

Nonnutritive swallowing and respiration relationships in preterm lambs.

The aim of the present study was to assess the effects of the different states of alertness on 1) nonnutritive swallowing (NNS) frequency, 2) the relationship between NNS and the respiratory cycle, and 3) the association of NNS with spontaneous apneas. Recordings of sleep states, diaphragm and laryngeal constrictor electrical activity, nasal flow, electrocardiogram, respiratory inductance pleth...

The distribution of respiration-related and swallowing-related motoneurons innervating the rat genioglossus muscle.

The present study was an attempt to identify the location of genioglossal respiratory and swallowing motoneuron cell bodies within the hypoglossal (XII) nucleus using both electrophysiological and morphological studies. The genioglossus muscle is innervated by the genioglossal branch of the medial XII nerve. At the entrance to the muscle, the genioglossal branch divides in the directions of the...
