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 soft palate is distinguished from the hard palate at the front of the mouth in that it does not ...
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 levator veli palatini (/ l ɪ ˈ v eɪ t ər ˈ v iː l aɪ ˌ p æ l ə ˈ t aɪ n aɪ /) is a muscle of the soft palate and pharynx. It is innervated by the vagus nerve (cranial nerve X) via its pharyngeal plexus. During swallowing, it contracts, elevating the soft palate to help prevent food from entering the nasopharynx.
The anatomy of the oral cavity is visualized; specifically, the assessor notes whether the base of the uvula, faucial pillars (the arches in front of and behind the tonsils) and soft palate are visible. Scoring is generally done without phonation. Depending on whether the tongue is maximally protruded and/or the patient asked to phonate, 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 ...
The palatine velum is slightly raised by the levator veli palatini and made tense by the tensor veli palatini; the palatopharyngeus muscles, by their contraction, pull the pharynx upward over the bolus of food and nearly come together, the uvula filling up the slight interval between them.
Each palatine bone somewhat resembles the letter L, and consists of a horizontal plate, a perpendicular plate, and three projecting processes—the pyramidal process, which is directed backward and lateral from the junction of the two parts, and the orbital and sphenoidal processes, which surmount the vertical part, and are separated by a deep ...
