What are the physiological functions of the uvula and what is the use of the uvula?

In Cihai, the word uvula is described as follows: uvula, commonly known as: uvula, commonly known"Small tongue", a small cone hanging in the middle of the posterior edge of the soft palate in the oral cavity, muscular structure, covered with mucosa, usually slightly drooping downward, with the soft palate contracting upwards when eating, to prevent food from the mouth from the mouth into the nasal cavity.

What is a uvula used for?

Prevent food and liquids from backing up into the nasal passages when swallowing.

There is a "small door" at the top of the esophagus and trachea that closes the esophagus when you breathe and the trachea when you swallow.

The actual function of the uvula is not entirely clear now, as it has been called in some recent otolaryngology professional journals"Mysterious uvula".Some languages need it to make a particular sound, (neither English nor Chinese) and the uvula can also help close the palate when we swallow and speak. In addition, some people can feel that it plays a role in removing saliva from the mouth.

The scientific name is "uvula", the anatomical name of the human body. Refers to the part of the mouth where the free margin of the soft palate protrudes downward.

uvulopalatopharyngoplasty is a common procedure for obstructive sleep apnea and snoring. The surgical indication is selected correctly, and the operation is safe and effective. During the operation, the noisy spine was cut to remove part of the ascending uvula, tonsils, and part of the soft palate, enlarge the pharyngeal cavity, reduce upper respiratory tract resistance during sleep, and improve ventilation.

Notes:

The amount of resection of the nasopharyngeal mucosa is less than that of the oropharyngeal mucosa. The mucosa is sutured with absorbable thread 0. Attention should be paid to anterior leaning of the mucosa during suturing to avoid a wound behind the soft palate (to prevent postoperative nasopharyngeal adhesions or stenosis).

All 286 patients were given anti-inflammatory hemostasis** after digging, and glucocorticoids were used short-term to alleviate wound edema and sore throat according to their own conditions.

The sutures were removed 8 to 9 days after surgery, and the average hospital stay was 15 days. The dotted line of the lateral palatopharyngeal arch indicates the area where the velopharyngeal arch is partially removed. The excessive folds of the left mucosa have been removed, and the mucosa of the pharyngeal wall has been stretched and flattened.

The palatopharyngeal arch is partially sutured with the palatalglossal arch, resulting in an enlargement of the oropharyngeal plane. The dotted line on the palate shows where the soft palate and uvula were removed.

uvula palatina [Landau Chinese-English dictionary]uvula is the name of the anatomical site [1]. Out of "The Yellow Emperor's Inner Scripture Lingshu: Sorrow and Speechlessness" [1]. It is also known as the small tongue ("The Secret of Laryngology", Volume II), Ti Ding ("Jiao's Laryngeal Pillow Secret", Volume 1), Di Zhong ("The Source of Miscellaneous Diseases" Volume 24), Laryngeal Flower ("The Source of Miscellaneous Diseases" Volume 24), Di Zhong ("The Source of Miscellaneous Diseases" Volume 24), Emperor Zhong [1], Emperor Zhong [1].

It is the part of the mid-soft palate that protrudes downward from the free margin [2]. [1] This can be seen by opening the mouth to make an "ah" sound. Together with the anterior pharyngeal column (lingual arch), the posterior pharyngeal column (pharyngeal palatine arch), and the laryngeal nucleus (palatine tonsils), it forms the laryngeal gateway [1].

The ancients believed that the uvula was related to sound [1]. "The Yellow Emperor's Inner Scripture Lingshu is Silent and Sorrowful": "Those who hang the nula are also the key to sound [1].

It hangs like a small tongue in the soft tissue, which contracts upward with the soft palate when swallowed, preventing food from entering the nasal cavity from the mouth [1].

The palate is the upper wall of the oral cavity that separates the nasal cavity from the oral cavity [3]. It can be divided into two parts: hard palate and soft palate[4][3]. The hard palate is bone-based and covered with mucosa [4]; The soft palate is attached to the hard palate, posterior to the palate1 3 [3], and consists of the palatine aponeurosis, palatine muscles, palatine glands, blood vessels, nerves, and mucous membranes [3].

The anterior part of the soft palate is horizontal; The latter part is obliquely posteriorly inferior and is called the palatal sail velum palatinum [3]. The posterior margin of the palatal sail is free, and there is a protrusion in the middle that perpendiculates downwards called the uvula or uvula [3][4].

Refers to the part of the mouth where the free margin of the soft palate protrudes downward.

The ancients believed that the uvula was associated with sound.

Lingshu Sorrow is Speechless": "The sound of the uvula, the key to the sound of speech." ”

The uvula, together with the tongue and palatine arches, pharyngeal palatine arches, and tonsils, form the laryngeal gateway.

Pronunciation is affected, buzzing, and nasal. One of my sisters was, by birth. I had surgery and made it up manually.

The absence of a uvula means that you can't learn the small tongue sounds in French and German.

Uvula. The small conus of the uvula, located in the middle of the posterior margin of the soft palate of the oral cavity, has a muscular structure, the surface is covered with mucosa, usually slightly drooping, and there are palatine tonsils on both sides.

The function of the uvula is to prevent food from flowing from the mouth into the nasal cavity when eating with the soft palate and shrinking upwards. participate in the enclosing of the pharyngeal gorge; Participate in the pronunciation of certain languages.

The uvula fissure is also known as the "bifid uvula". Examination of the patient's pharynx reveals a small notch at the tip of the uvula or until the root of the uvula is completely dehiscence, which is one of the congenital malformations.

It is due to the fact that during embryonic development, the two lateral fissure processes do not fuse with each other, resulting in abnormal development of the two halves of the soft palate during the closing process, often accompanied by palate fissures or short palate deformities. If it is mild, it does not affect swallowing. In severe cases, swallowing disorders or speech disorders may occur due to velopharyngeal insufficiency, and due to the concomitant palatine muscle defect, the Eustachian tube is not open properly, and it is easy to develop exudative otitis media or acute and chronic suppurative otitis media.
