There are a few things to keep in mind when using ngApp: 1  only one AngularJS application can be auto-bootstrapped per HTML document. 2  AngularJS applications cannot be nested within each other.  Do not use a directive that uses transclusion on the same element as ngApp.
The esophagus is the tube that carries food, liquids and saliva from your mouth to the stomach. You may not be aware of your esophagus until you swallow something too large, too hot or too cold. You may also become aware of it when something is wrong.
Presbyesophagus is a term used to describe an abnormal shape of the swallowing tube (esophagus) that occurs in some individuals. In this situation, the esophagus appears wavier than a typically straight esophagus. This change may impact esophageal movement (motility).The term presbyesophagus (presby is Latin for old) was originally used to describe a change in esophagus movement related to aging even though there has been limited evidence that aging by itself causes trouble swallowing.our doctor will likely perform a physical examination and use a variety of tests to determine the cause of your swallowing problem. These tests could include a barium swallow x-ray, an upper endoscopy (EGD), or an esophageal motility test (manometry).
