Does the soft palate rises reflexively to open the nasopharynx when we swallow food?

Does the soft palate rises reflexively to open the nasopharynx when we swallow food?

The soft palate rises reflexively to open the nasopharynx when we swallow food. When swallowing, the epiglottis prevents food from entering the larynx. Some of the microbes that often invade other organs of the body are rarely found in the stomach. The reason for this is the presence of HCl.

When you swallow which structure rise to close off the nasopharynx?

soft palate
Usually during swallowing, the soft palate and uvula rise reflexively to close off the entrance to the nasopharynx.

What event triggers the opening of the gastroesophageal sphincter?

The event that triggers the opening of the gastroesophageal sphincter is C) Peristalsis in the esophagus.

What Mouth part helps to mix food with saliva moves food toward the pharynx for swallowing and houses taste receptor cells?

Another enzyme called lipase is produced by cells in the tongue to break down fats. The chewing and wetting action provided by the teeth and saliva prepare the food into a mass called the bolus for swallowing. The tongue helps in swallowing—moving the bolus from the mouth into the pharynx.

Which of the following is a function of the nasopharynx?

The nasopharynx is the space above the soft palate at the back of the nose and connects the nose to the mouth, which allows a person to breathe through the nose.

Which portion of the pharynx connects with the esophagus?

Laryngopharynx. The laryngopharynx, (Latin: pars laryngea pharyngis), also known as hypopharynx, is the caudal part of the pharynx; it is the part of the throat that connects to the esophagus.

When you swallow which structures rise to close off the nasopharynx quizlet?

Uvula-During swallowing, the soft palate and the uvula move superiorly to close off the nasopharynx, preventing food from entering the nasal cavity. When this process fails, the result is called nasal regurgitation. Palatine Tonsils-There is one located on each side of the oral pharynx, in the back of the throat.

What is the benefit of having tonsils at the oral entry to the pharynx?

What is the benefit of having tonsils at the oral entry to the pharynx? The tonsils gather and remove many of the pathogens entering the pharynx in food or liquid.

Which of the following intestinal hormones stimulates the release of bile from the gall bladder?

Cholecystokinin stimulates the gallbladder to contract and release stored bile into the intestine.

What is the pharynx?

The hollow tube inside the neck that starts behind the nose and ends at the top of the trachea (windpipe) and esophagus (the tube that goes to the stomach). The pharynx is about 5 inches long, depending on body size. Also called throat.

What mouth part helps mix food with saliva?

Saliva from the salivary glands moistens the food and makes it easier to chew. The muscular tongue helps mix the food with saliva and the enzymes it contains. When you swallow, the lump of chewed food, now called a bolus, passes into the pharynx. The pharynx connects the mouth to the rest of the digestive tract.

What is the function of the soft palate?

The soft palate is continuous with the hard palate, which forms in the anterior roof of the mouth. The soft palate plays an essential role in blocking food and other substances from entering the nasal passages during swallowing and is important in the formation of certain sounds in speech production.

Why does the soft palate block the back nasal passage?

That’s because the passage remains open when a person is not swallowing food, thus allowing him to breathe through the mouth and nose. However, the soft palate moves upward and blocks off the entrance to the back nasal passage when a person is swallowing food, preventing regurgitation of food into the nasal cavities.

Where is the soft palate attached to the pharynx?

The soft palate projects into the cavity of the pharynx from its attachment to the posterior edge of the hard palate. When elevated, it separates the oropharynx from the nasopharynx. Five paired muscles attach to the soft palate and contribute to its structure.

How does the palatopharyngeus receive its motor supply?

Palatopharyngeus receives its motor supply from the pharyngeal plexus. The uvular muscle, also supplied by the pharyngeal plexus, lies entirely within the soft palate and elevates the uvula. In cases of unilateral paralysis of the soft palate, the uvula rises asymmetrically, being pulled away from the paralyzed side.

How does the soft palate affect snoring?

When you swallow, the soft palate and uvula move upward, helping to keep foods and liquid from entering the nasal cavity. Unfortunately, it can also contribute to the sound produced by snoring. Two muscular folds extend downward from the soft palate, on either side of the uvula.
