There are 4 phases of swallowing:

• The Pre-oral Phase. – Starts with the anticipation of food being introduced into the mouth – Salivation is triggered by the sight and smell of food (as well as hunger)

What are the 2 types of dysphagia?

Dysphagia has two main types: structural dysphagia, which results from changes to the actual structure of your esophagus, or dysphagia caused by esophageal motility (movement) issues. In some cases, dysphagia results from certain changes to the physical structure of the esophagus.

What is a Level 3 dysphagia diet?

A level 3 diet is the least limited. It is used as a transition to a normal diet. People on this diet can eat bite-sized pieces of moist foods with near-normal textures. They should avoid very hard, sticky, or crunchy foods, such as dried fruit or nuts.

What is the deglutition reflex?

One of the most important components of swallowing is deglutition reflex, an automatic swallowing reflex which take place when the bolus reaches the base of the tongue. Deglutition reflex is a motor signal in which deglutition center sands impulses to the pharynx and the upper esophagus to swallow bolus.

What happens if the process of deglutition fails?

If the process of swallowing fails, then pulmonary aspiration (going down the wrong pipe) or choking can occur. The whole process of deglutition is divided into three phases: oral phase. pharyngeal phase. esophageal phase.

What is the first stage of deglutition?

Oral phase The oral phase of swallowing is the first stage of deglutition, and it is a voluntary process. It is also commonly known as the buccal phase. It involves the contraction of the tongue to push the bolus up against the soft palate and then posteriorly into the oropharynx by both the tongue and the soft palate.

What happens during the esophageal phase of deglutition?

In the esophageal phase of deglutition, the bolus moves involuntarily into the esophagus. During this final stage, upper esophageal sphincter relaxes to allow bolus to pass.
