Pharyngeal 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 کاملThe Ascending Pharyngeal Artery
The ascending pharyngeal artery of the dog was investigated by means of the acryl plastic injection method. This artery usually arose from the external carotid artery, sometimes from the occipital, the posterior auricular, or rarely the ascending palatine of the lingual artery. It ran forwards between the vagus and hypoglossal nerves and continued anteromedially up to the posterolateral wall of...
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...
متن کاملPharyngeal Packing during Rhinoplasty: Advantages and Disadvantages
Introduction: Controversy remains as to the advantages and disadvantages of pharyngeal packing during septorhinoplasty. Our study investigated the effect of pharyngeal packing on postoperative nausea and vomiting and sore throat following this type of surgery or septorhinoplasty. Materials and Methods: This clinical trial was performed on 90 American Society of Anesthesiologists (ASA) I or II...
