The process of deglutition begins with the bolus formation in the oral cavity.
These are inhibitory reflexes, excited by deglutition , by gastric distension, and by intestinal dilatation.
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.
the muscles involved in deglutition
Other factors include general anesthesia, loss of consciousness, structural abnormalities of the pharynx and neuromuscular disorders, deglutition abnormalities.
oesophageal pressure peaks induced by a single deglutition
The act of deglutition will not be accompanied with pain or soreness, but extreme anxiety and violent palpitations of the heart.
This is primarily due to the impairment of pharyngeal bolus transportation, which predisposes the patient to develop post deglutitive aspiration.
Sudden eruption of the deglutitive phase occurs in states of collapse and shock.
The proposed muscle strengthening exercise program is effective in restoring oral feeding in some patients with deglutitive failure.
