What is the movement of a swallow?

What is the movement of a swallow?

Swallowing, or deglutition, is a complex reflex mechanism by which food is pushed from the oral cavity into the esophagus and then pushed to the stomach. This movement of food from the oral cavity on to the esophagus and stomach by pushing is called propulsion, and it is an important part of the digestive process.

What causes Epiglottic inversion?

It appears that epiglottic inversion correlates with the action of the pharyngeal constrictor muscles as well as laryngeal elevation and tongue base retraction. This may be attributable to the glossopharyngeal part of the superior pharyngeal constrictor facilitating tongue base retraction.

What moves the epiglottis upon swallowing?

The movements of the epiglottis are regulated by the passive movements of the tongue and hyoid bone and by the actions of the aryepiglottic muscles. In the initial stage of swallowing, the tongue pushes the food towards the oropharynx. The suprahyoid muscles pull the hyoid bone anterosuperiorly.

How can I improve my swallowing?

As example, you may be asked to:

1. Inhale and hold your breath very tightly.
2. Pretend to gargle while holding your tongue back as far as possible.
3. Pretend to yawn while holding your tongue back as far as possible.
4. Do a dry swallow, squeezing all of your swallowing muscles as tightly as you can.

When swallowing the glottis covers the epiglottis?

air passes through the glottis on its way to the trachea. the epiglottis is an elastic cartilage structure located at the superior portion of the larynx. during swallowing the epiglottis covers the larynx opening to prevent food and liquids from entering the respiratory tract.

How are the movement patterns of the epiglottic recorded?

Epiglottic dysfunction: abnormal epiglottic movement patterns Epiglottic movement patterns of 500 consecutive patients with varying etiologies were recorded during routine videofluoroscopic swallow evaluations. Seven distinct, commonly repeated, abnormal epiglottic patterns were identified.

Is there an article on epiglottic dysmotility?

A recent article on epiglottic dysfunction is one by Garon BR, Huang Z, Hommeyer S, et al., ”Epiglottic dysfunction: abnormal epiglottic movement patterns”. Dysphagia 17: 57-68, 2002. It has references to many other excellent studies.

Which is the best treatment for immobile epiglottis?

In answer to the question about what treatment should be prescribed for an ‘immobile epiglottis’, we must first determine the cause. If it is an anatomical change, the best treatment may be to find the head and neck position that allows fullest passage of the bolus during swallowing.

What happens to the epiglottis after radiation therapy?

After radiation therapy, the epiglottis can be edematous or friable and not be as mobile as it used to be. Sometimes, the epiglottis is very mobile, and the muscles are strong, but a cervical oesteophyte impinges into the pharyngeal airspace, making the passage much more narrow.
