The reflex is initiated by touch receptors in the pharynx as a bolus of food is pushed to the back of the mouth by the tongue, or by stimulation of the palate (palatal reflex). Swallowing is a complex mechanism using both skeletal muscle ( tongue ) and smooth muscles of the pharynx and esophagus .
Oropharyngeal dysphagia; Other names: Transfer dysphagia: The digestive tract, with the esophagus marked in red: Specialty: Gastroenterology, ENT surgery: Symptoms: Hesitation or inability to initiate swallowing, food sticking in the throat, nasal regurgitation, difficulty swallowing solids, frequent repetitive swallows. frequent throat clearing, hoarse voice, cough, weight loss, and recurrent ...
In a reflex arc, a series of physiological steps occur very rapidly to produce a reflex.Generally, a sensory receptor receives an environmental stimulus, in this case from objects reaching nerves in the back of the throat, and sends a message via an afferent nerve to the central nervous system (CNS).
In problems of heat transfer with phase change, for instance, conservation of energy dictates that the discontinuity of heat flux at the boundary must be accounted for by the rate of latent heat release (which is proportional to the local velocity of the interface).
The pharynx (pl.: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food to the esophagus and air to the larynx.
In physics, chemistry, and other related fields like biology, a phase transition (or phase change) is the physical process of transition between one state of a medium and another. Commonly the term is used to refer to changes among the basic states of matter : solid , liquid , and gas , and in rare cases, plasma .
The larynx (/ ˈ l æ r ɪ ŋ k s /), commonly called the voice box, is an organ in the top of the neck involved in breathing, producing sound and protecting the trachea against food aspiration. The opening of larynx into pharynx known as the laryngeal inlet is about 4–5 centimeters in diameter. [1]
