Pharyngeal swallowing phase and chronic cough
INTRODUCTION The act of swallowing depends on a complex and dynamic process which uses common structures to the act of breathing; respiratory problems can cause swallowing difficulties. AIM To assess the swallowing pharyngeal phase in patients with chronic cough. METHOD Retrospective study with 15 patients of both genders, patients with chronic cough and risk factors for aspiration defin...
متن کاملUrge to cough with voluntary suppression following mechanical pharyngeal stimulation.
OBJECTIVE The goal of this project was to determine if mechanical stimulation to the posterolateral oropharynx would elicit the urge-to-cough and/or cough. BACKGROUND Inhaled agents, such as capsaicin and citric acid, readily produce coughing and the sensation of urge-to-cough. Areas below the glottis are thought to be the primary sensory mediators of these responses, however it is unknown if...
متن کاملPharyngeal constrictions.
From a fiberscope, the tip of which was swung from left to right in the pharynx, cinefilm frames were obtained which showed the cross-sectional shape of pharyngeal constrictions in back vowels. This information was combined with the information offered by X-ray pictures of the same subject phonating the same vowels on a different occasion. The results agree to a reasonable extent with previousl...
متن کاملMechanical effects of pharyngeal constrictor activation on pharyngeal airway function.
The mechanical effects of pharyngeal constrictor (PC) muscle activation on pharyngeal airway function were determined in 20 decerebrate, tracheotomized cats. In 10 cats, a high-compliance balloon attached to a pressure transducer was partially inflated to just occlude the pharyngeal airway. During progressive hyperoxic hypercapnia, changes in pharyngeal balloon pressure were directly related to...
متن کاملMethods for measuring pharyngeal behaviors.
The pharynx is a neuromuscular pump at the anterior end of the alimentary tract. It is made up of 20 muscle cells, 20 neurons, and 20 other cells. Pharyngeal activity correlates with food intake. The proper feeding rate, as well as the precise timing of pharyngeal movements, is required for efficient feeding and likely for survival in nature. For most purposes, pharyngeal behavioral analysis re...
