What is a tasting?

Deglutice is a scientific term for the word swallowing. It came from the Latin word deglutire , which means "swallow". The muscles in the tongue, pharynx and esophagus are involved in the process of deglutice, which is divided into three phases: oral phase, pharynic phase and esophagus phase. At these stages, many important roles are also played.

The oral phase is usually a voluntary phase, which means that it is often consciously performed by an individual. It starts when the food enters the mouth. The process of chewing or chewing the food breaks into smaller pieces. Then the tongue pushes pieces of food towards the pharynx or back of the neck. The cranial nerves that are involved during the oral phase are trigeminal nerve, facial nerve and hypoglossal nerve. Uvula and a soft floor usually prevents food from the nose to cover the nosopharynx, which opens into the nasal cavities. At the same time, the deglutic reflex begins with food to the esophagus and away from the lungs using Epiglottis, a tissue flap that covers the larynx. BThis process leads to tasting apnea, which means that breathing takes a very short time. Cranial nerves involved during this phase include vagus, accessories and hypoglossal nerves.

The esophagus phase, which also occurs involuntarily, begins with the opening of the esophagus sphincter to enter her food. When the food reaches the end of the esophagus, another muscle opens, called a heart sphincter to pass the food into the stomach for digestion. Sphinkter is a muscular ring that contradicts and relaxes, either prevents, or allows the materials to pass from one area to Next, between the esophagus and the stomach.

disorders of tastics sometimes occur in elderly, especially after stroke. Because the cranial nerves are often affected in patients with a stroke, food particles can sometimes enter the lungs and cause infection. Any congenital defect, infection, obstruction, injury or cancer growth in pharynx do notBo esophagus may affect the tasting process. Dysphagia or swallowing problems is the most common symptom of disorder of tastics. Another symptom is odynofhage or pain during swallowing.
