Vegetative Functions of the VP-Nasal Mechanism

These flashcards cover key vocabulary terms related to the vegetative functions of the VP-nasal mechanism and swallowing processes.

Ventilation

Movement of air in and out of the pulmonary mechanism.

Nasal Breathing

Breathing through the nose, which warms, moistens, and filters air.

Oral Breathing

Switching to breathing through the mouth, often due to the need for more air.

VP Port Closure

Prevents food or liquid from entering the nasal cavity during swallowing.

Nasal Regurgitation

The return of food or liquid back into the nasal cavity (nose)

Oral Preparatory Phase

Phase of swallowing where food or liquid is prepared for swallowing.

Oral Transit Phase

Phase of swallowing where the bolus is pushed from the mouth to the throat.

Pharyngeal Transport Phase

Phase where the bolus travels through the throat to reach the esophagus.

Esophageal Phase

Phase where the bolus travels through the esophagus to reach the stomach.

Boyle’s Law

Describes the relationship between space and pressure during swallowing.

Modified Barium Swallow Study (MBSS)

An X-ray technique to evaluate swallowing using barium.

Penetration

When the bolus enters the airway above the level of the vocal folds.

Aspiration

When the bolus enters the airway and goes below the level of the vocal folds.

Flexible Endoscopic Evaluation of Swallowing (FEES)

A technique using a flexible scope to view the larynx before and after the swallow.

Swallowing phase order

1. Oral Preparatory (open)

2. Oral transit phase (closed)

3. Pharyngeal phase (open)

4. Esophageal phase (closed)
