Histochemical properties of upper airway muscles: comparison of dilator and nondilator muscles.
The upper airway dilator muscles (UADMs) represent a subgroup of muscles in the pharyngeal area which, in addition to their roles in mastication, vocalization, etc., also have an important respiratory function. Failure of these muscles to maintain upper airway patency during sleep is important in the development of the obstructive sleep apnoea syndrome. In the present study, we evaluated the hi...
متن کاملInfluence of posture and breathing route on neural drive to upper airway dilator muscles during exercise.
Our purpose was to determine the influence of posture and breathing route on electromyographic (EMG) activities of nasal dilator (NDM) and genioglossus (GG) muscles during exercise. Nasal and oral airflow rates and EMG activities of the NDM and GG were recorded in 10 subjects at rest and during upright and supine incremental cycling exercise to exhaustion. EMG activities immediately before and ...
متن کاملResidual neuromuscular blockade and upper airway muscles.
We appreciate the opportunity to review and respond to the letter to the editor by Culp, Brewster, and Wernicki, in response to our review article. We thank the authors for their complimentary remarks. We are also pleased that they chose to respond and emphasize the need for prevention and rescue of drowning persons to further improve the survival rate from this disaster. They make the point th...
متن کاملElectrically-activated dilator muscles reduce pharyngeal resistance in anaesthetized dogs with upper airway obstruction.
There is current controversy as to whether electrical stimulation of upper airway musculature can be used us a beneficial treatment modality in patients with obstructive sleep apnoea syndrome. Increased upper airway (UAW) muscle activity decreases UAW resistance (Ruaw) in isolated UAW of dogs. In the present study, we evaluated the effect of UAW muscle contraction on UAW patency in anaesthetize...
متن کاملActivation of upper airway muscles during breathing and swallowing.
The upper airway is a complex muscular tube that is used by the respiratory and digestive systems. The upper airway is invested with several small and anatomically peculiar muscles. The muscle fiber orientations and their nervous innervation are both extremely complex, and how the activity of the muscles is initiated and adjusted during complex behaviors is poorly understood. The bulk of the ev...
