While swallowing, the soft palate is pushed backwards, preventing food and drink from entering the nasal cavity. If the soft palate cannot touch the back of the throat while swallowing, food and drink can enter the nasal cavity. [6] Splitting of the uvula occurs infrequently but is the most common form of mouth and nose area cleavage among ...
The soft palate (also known as the velum, palatal velum, or muscular palate) is, in mammals, the soft tissue constituting the back of the roof of the mouth. The soft palate is part of the palate of the mouth; the other part is the hard palate .
The reflex is initiated by touch receptors in the pharynx as a bolus of food is pushed to the back of the mouth by the tongue, or by stimulation of the palate (palatal reflex). Swallowing is a complex mechanism using both skeletal muscle and smooth muscles of the pharynx and esophagus.
Nasopharyngoscopy provides a view of the velum (soft palate) and pharyngeal walls (walls of the throat) during nasal breathing and during speech. The advantage of this technique over videofluoroscopy is that the examiner can see the size, location, and cause of the velopharyngeal opening very clearly and without harm (e.g., radiation) to the ...
The gag reflex involves a brisk and brief elevation of the soft palate and bilateral contraction of pharyngeal muscles evoked by touching the posterior pharyngeal wall. Touching the soft palate can lead to a similar reflex response. However, in that case, the sensory limb of the reflex is the CN V (trigeminal nerve). In very sensitive ...
To use the appropriate size is selected, and then the OPA is inserted with the tip towards the roof of the mouth. When the tip has reached the soft palate of the mouth, the OPA is rotated so the tip is facing the feet of the patient. OPAs are not to be used on conscious patients, or patients with a gag reflex.

Meanwhile, the soft palate, located in the back of the mouth, has three positions for controlling airflow: raised, neutral, and lowered. When it's raised, air may flow through the mouth to the lungs; when it's dropped, air can only flow through the nose. The soft palate in its neutral posture allows air to flow freely through both the nose and ...
The surface of the hard palate allows for the pressure needed in eating food, to leave the nasal passage clear. [8] The opening between the lips is termed the oral fissure, and the opening into the throat is called the fauces. [9] At either side of the soft palate are the palatoglossus muscles which also reach into regions of the tongue. These ...
