(1) The act of deglutition will not be accompanied with pain or soreness, but extreme anxiety and violent palpitations of the heart.(2) the muscles involved in deglutition(3) The process of deglutition begins with the bolus formation in the oral cavity.(4) Other factors include general anesthesia, loss of consciousness, structural abnormalities of the pharynx and neuromuscular disorders, deglutition abnormalities.(5) Organic abnormalities of deglutition may be related to initiation of the swallowing reflex in the oropharynx or to propulsion of the food bolus through the esophagus.(6) These are inhibitory reflexes, excited by deglutition , by gastric distension, and by intestinal dilatation.(7) oesophageal pressure peaks induced by a single deglutition(8) EGJ opening diameter during deglutitive relaxation was on average 0.5 cm greater in GERD patients compared with normal subjects and fundoplication patients.(9) This is primarily due to the impairment of pharyngeal bolus transportation, which predisposes the patient to develop post deglutitive aspiration.(10) Sudden eruption of the deglutitive phase occurs in states of collapse and shock.(11) However incomplete deglutitive relaxation in LES and primary peristaltic waves were detected in several patients with achalasia.(12) The proposed muscle strengthening exercise program is effective in restoring oral feeding in some patients with deglutitive failure.
