|
The Pharyngeal phase.
|
|
|
the following are examples of what type of swallowing treatment?
1.increase the range of tongue movement. 2. increase buccal tension 3. increase the range lateral movement of the tongue |
Indirect Treatment of Swallowing Disorders.
|
|
|
Supraglottic Swallow:
|
Helps close the airway at the level of the vocal folds to prevent aspiration. The clinician will ask the patient to hold the food in the mouth , take a deep breath and hold it soon after initiating a slight exhalation, swallow while holding the breath , and cough soon after the swallow.
|

|
What is the affect of damage to the SLN ( superior laryngeal nerve)?
|
SLN is the internal branch of the Vagus Nerve. it carried sensory input to the supraglottic larynx, cricoarytenoid joint, posterior aspect of the larynx, and the pharyngeal mucosa in the piriform sinuses. Loss of function results in loss of sensation of the supraglottis and the piriform sinuses, which can lead to aspiration.
|
|
|
Glossopharyngeal Nerve ( CN:IX
|
Provides sensory innervation to the oropharynx and the base of the tounge and supports taste at the base of the tongue. The motor innervation is the stylophraygeus muscle which helps in elevating and opening the pharynx.
|
|
|
Hypoglossus Nerve:
|
retracts and depresses tongue.
damage to this nerve can reuslt in tongue paralysis, diminished intelligibility, and swallowing problems. |
|
|
RLN( Recurrent Laryngeal Nerve):
|
A branch of the vagus nerve, that regulates intrinsic laryngeal muscles except for the criocthyroid. Damage to this nerve can cause total paralysis of the vocal fold. Significant problems for swallowing.
|
|
|
What is the result of a weak cricopharygneus muscle?
|
The cricopharyngeus muscle helps with constricting the UES. Damage to this muscle can cause to reflux of material from the esophagus to the pharynx, also decreases the amount of air in to the gasterointestinal tract.
|
|
|
What is the result of a weak laryngeal sphnicter?
|
The laryngel sphincter helps to protect the air way by closing of the true vocal folds,false vocal folds, and the arytenoids. failure to do so results in penetration or aspiration.
|

|
Name the four phases of swallowing:
|
Oral preparatory
Oral Pharyngeal Esophageal |
