During deglutition (swallowing), the soft palate rises to close off the nasopharynx, the larynx elevates, and the epiglottis folds over the glottis. The esophagus includes an upper esophageal sphincter made of skeletal muscle, which regulates the movement of food from the pharynx to the esophagus.

What muscle elevates the soft palate?

The levator veli palatini muscle emerges from the eustachian tube and the petrous temporal bone before attaching to the palatine aponeurosis, this muscle functions to elevate the soft palate during swallowing to prevent the entry of food into the nasopharynx.

What happens to soft palate during swallowing?

During swallowing, the soft palate is pulled up, causing it to press against the posterior pharyngeal wall. When elevated in this way, it completely blocks and separates the nasal cavity and nasal portion of the pharynx from the mouth and the oral part of the pharynx.

How does soft palate help Deglutition?

During the pharyngeal stage, the soft palate elevates and contacts the lateral and posterior walls of the pharynx, closing the nasopharynx at about the same time that the bolus head comes into the pharynx (Fig. 5). Soft palate elevation prevents bolus regurgitation into the nasal cavity.

What happens during Deglutition?

Deglutition is the transport of a bolus of food or liquid from the mouth to the stomach. Normal deglutition requires precisely timed contraction and relaxation of numerous muscles of the oral and pharyngeal regions (Table 54-1).

Which stage can we stop the process of swallowing a bolus of food?

Is swallowing a reflex action?

What is the main function of the soft palate?

The soft palate comprises muscle and tissue, which make it mobile and flexible. When a person is swallowing or sucking, the soft palate completely separates the mouth from the throat, which helps keep food out of the respiratory tract. The soft palate is also known as the muscular palate or the velum.

What causes the soft palate to drop?

While you are awake, the muscles around the soft palate keep your airway open. But as you fall asleep, these muscles start to relax. In people with OSA, the muscles relax so much that the soft palate tissue collapses and blocks the airway. If your airway becomes blocked, your breathing slows or stops altogether.

Is Vellum the same as soft palate?

Upper respiratory system, with soft palate labeled near center. 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.

  3. Drinking plenty of water to prevent dehydration.
  4. Gargling with warm salty water to ease throat pain.

What forms posterior 1/3 of the hard palate?

The ethmoid bone also contributes to the formation of facial structures. The maxilla forms the upper jaw and the mandible forms the lower jaw. The maxilla also forms the larger anterior portion of the hard palate, which is completed by the smaller palatine bones that form the posterior portion of the hard palate.

How do you speak with a raised soft palate?

Locate your soft palate and try to move it. If you aren't sure how to move it, say “Hung-ah” and watch the soft palate and tongue meet and then separate. Say the “Hung-ah” several more times until you can feel the muscles that move the soft palate. Try to move the soft palate up and then release.

Poor oral hygiene can lead to a buildup of bacteria in the mouth. When these bacteria multiply, it can change the color of the inside of the mouth. This may cause the roof of your mouth and your tongue to turn yellow.

What is the main purpose of the swallow reflex?

The swallowing reflex produces sequential activation of the tongue, pharyngeal and laryngeal muscles to propel the food bolus from the oral cavity to the esophagus without aspiration of food into the airways (Doty and Bosma, 1956; Umezaki et al., 1998). The larynx plays a critical role in swallowing.

What happens if food or bolus enters the larynx or trachea instead?

Further, the epiglottis may fail to completely cover the trachea during swallowing and food or liquid may enter the trachea. This can cause coughing and choking. Aspiration occurs if the food or liquid is not removed with coughing or choking, but instead enters the lungs.

What happens to the throat and esophagus as you swallow the food?

As a person swallows, food moves from the mouth to the throat, also called the pharynx (1). The upper esophageal sphincter opens (2) so that food can enter the esophagus, where waves of muscular contractions, called peristalsis, propel the food downward (3).

Is swallowing an involuntary action?

The act of swallowing has voluntary and involuntary components. The preparatory/oral phase is voluntary, whereas the pharyngeal and esophageal phases are mediated by an involuntary reflex called the swallowing reflex.
