Where is the soft palate

I don’t know if you have ever experienced being looked down upon because of your unpleasant voice. If you want to change your voice, you can also change it through oral exercises. If it is too soft, it can effectively change your own timbre and avoid the occurrence of nasal sound. Because there are many connective tissues on the soft palate, it is the main active part of the human upper jaw. Where is the soft palate located in the human mouth?

Soft Palate: The back part of the palate (roof of the mouth), made up of connective tissue and muscle. Refers to the posterior 1/3 of the upper wall of the oral cavity, which is mainly composed of muscles, tendons and mucosa. It is attached to the posterior edge of the hard palate and extends posteriorly and downwards. It is the movable part of the palate and is also known as the palatine velum. It is mainly composed of mucosa, submucosal tissue, palatine aponeurosis and palatine muscles, and is about 1 cm thick. The mucosa is continuous with the hard palate mucosa, but its texture is soft and smooth. There is a symmetrical palatal depression on each side of the mucosa on the midline of the front end, which is equivalent to the junction of the soft and hard palate. The soft palate mucosa contains a large number of mucous glands, and the deep side is the palatine aponeurosis and palatine muscles. The palatine aponeurosis is located in the anterior 1/3 of the soft palate and is attached to the posterior edge of the hard palate, forming the support of the soft palate. The palatine mucosa is thick near the hard palate and becomes thinner toward the back. The palatine muscles are all located in the posterior 2/3 of the soft palate and continue with the palatine mucosa in front. The coordinated movement of the palatine muscles and pharyngeal muscles can control the closure of the palatopharynx, and plays an important role in speech, swallowing, breathing and other functions. The posterior edge of the soft palate is free, and on both sides are the palatoglossal arch and palatopharyngeal arch.

Part of the palate. It occupies about the posterior 1/3 of the palate and together with the hard palate forms the upper wall (roof) of the oral cavity. The front part of the soft palate is almost horizontal, and the back part is slanted downward and backward, called the palatine velum. The posterior edge is free, and there is a downward round protrusion in the center, which is the uvula. There are two folds on both sides of the palatine velum: the front one moves downward to the root of the tongue, called the palatoglossal arch; the back one moves to the pharyngeal wall, called the pharyngeal palatine arch. The triangular depression between the two arches is called the tonsillar sinus, which houses the tonsils. The soft palate is a mucosal fold that contains the palatine aponeurosis, palatine muscles, palatine glands, blood vessels, nerves, etc.

Anatomy:

The soft palate can be regarded as a large and thick mucosal fold, under which the mucosa contains the palatine aponeurosis, blood vessels, nerves, criss-crossing striated muscle fiber bundles and a large number of glands. The soft palate is attached to the posterior edge of the hard palate, while the periosteum of the hard palate extends into the soft palate and is interspersed with the tendon fibers of the tensor veli palatini. The soft palate hangs downward and backward like a sail, so it is called the palatine velum. It is concave forward and downward and slightly convex upward and backward. The posterior edge of the soft palate is free and drooping, with a nipple-like protrusion in the center called the uvula, which varies in shape and size from person to person. From both sides of the uvula along the free edge of the soft palate to the lateral wall of the pharynx, it descends to form two anterior and posterior arch-like folds. The former is called the palatoglossal arch, and its terminal end ends at the edge of the tongue with a triangular fold; the latter is called the palatopharyngeal arch, which is more significant than the palatoglossal arch, descends and disappears in the lateral wall of the pharynx. There is a recess between the two arches, called the tonsillar sinus, in which the palatine tonsils are located. The narrow area surrounded by the left and right pairs of palatine arches, the free edge of the soft palate and the root of the tongue is called the pharyngeal isthmus, which is the narrow passage from the oral cavity to the pharyngeal cavity.
