The palate is the roof of the mouth, consisting of a hard palate in the front and a soft palate at the back. The soft palate is a muscular flap that moves during breathing, swallowing, and speech. It is responsible for closing off the nasal passages during swallowing and speech, preventing air from escaping through the nose and giving speech a nasal quality. The soft palate is composed of five muscles, one of which is the levator veli palatini, which elevates the palate.

The soft palate is a muscle flap that aids speech, swallowing and breathing
The soft palate is a muscular flap that separates the mouth from the nose, acting as a barrier between the digestive and respiratory tracts. It is composed of muscle fibres covered by a mucous membrane. The soft palate is mobile and movable, and its movement is produced by five muscles, namely:
- Tensor veli palatini
- Musculus uvulae
- Levator veli palatini
- Palatopharyngeus
- Palatoglossus
The levator veli palatini muscle is responsible for elevating the soft palate. During swallowing, the soft palate tenses and helps push food down the digestive tract. Immediately after this, the soft palate elevates and closes the way to the nasal cavity, ensuring that no food can pass back to the nasal airways. During nasal breathing, the soft palate depresses and gets in touch with the root of the tongue, ensuring that food doesn't pass to the oropharynx and instead gets in the way of the stream of exhaled air.
The soft palate also plays an important role in speech. During speech, the soft palate tenses and elevates, and the back of the tongue presses against it to produce velar sounds, such as [k], [g] and [ŋ] in English. The movement of the soft palate is crucial in closing the communication with the nasal cavity during speech. If this separation is incomplete, air escapes through the nose, causing speech to sound nasal.

The soft palate is elevated during swallowing to prevent food from entering the nasal cavity
The palate is the roof of the mouth, separating the oral and nasal cavities. It consists of a hard palate at the front and a soft palate at the back. The soft palate is a mobile musculoaponeurotic flap, meaning it can be moved by muscles. It is responsible for closing off the nasal passages during swallowing and speech.
The soft palate is composed of five muscles: the tensor veli palatini, levator veli palatini, musculus uvulae, palatopharyngeus, and palatoglossus. These muscles are innervated by the pharyngeal plexus via the vagus nerve, except for the tensor veli palatini, which is innervated by the mandibular division of the trigeminal nerve (V3). During swallowing, the soft palate tenses and helps push food down the digestive tract.
Immediately after this, the soft palate elevates and closes off the nasal cavity, preventing food from entering the nasal airways. This elevation is caused by the levator veli palatini muscle. The soft palate also elevates during speech, tensing to close off the nasal cavity so that air does not escape through the nose, which would make the speech sound nasal.
The palatoglossal arch is located at the front of the soft palate and contains the palatoglossus muscle, connecting the soft palate with the root of the tongue. The palatopharyngeal arch is found at the back and contains the palatopharyngeus muscle, joining the soft palate with the wall of the pharynx. These arches are also known as the pillars of fauces, as they bound the space called the fauces, or the throat.

The soft palate is one of two parts of the palate, the other being the hard palate
The palate, or the 'roof of the mouth', is divided into two parts: the hard palate and the soft palate. The hard palate is positioned anteriorly and is made up of bones from the maxilla and palatine bones. It is immobile and forms the floor of the nasal cavity. The superior aspect of the hard palate is covered by a ciliated pseudostratified columnar epithelium (respiratory mucosa), while the inferior aspect is lined with stratified squamous epithelium (oral mucosa) containing secretory salivary glands.
The soft palate is located posteriorly and is made up of muscle fibres covered by a mucous membrane. It is mobile and plays a crucial role in speech, breathing, and swallowing. During swallowing, the soft palate tenses and elevates, closing off the nasal cavity and preventing food from entering it. The soft palate is also important for producing certain speech sounds, such as [k], [g], and [ŋ] in English, by tensing and elevating to close off the nasal cavity.
The soft palate is comprised of five muscles that originate from either the base of the skull or the pharyngeal walls and travel in various directions to reach the soft palate. These muscles are the musculus uvulae, tensor veli palatini, levator veli palatini, palatopharyngeus, and palatoglossus. The tensor veli palatini tenses the soft palate during swallowing, while the levator veli palatini elevates it. The palatopharyngeus joins the soft palate to the wall of the pharynx, and the palatoglossus connects the soft palate to the root of the tongue.
The hard palate and soft palate have distinct functions and structures, but they work together to form the roof of the mouth and separate the nasal cavity from the oral cavity. The hard palate provides a rigid structure, while the soft palate is flexible and mobile, allowing for the elevation and tension necessary for speech and swallowing functions.

The soft palate is made up of five muscles, four of which are innervated by the pharyngeal plexus via the vagus nerve
The soft palate is a muscular flap that separates the nasal and oral cavities. It facilitates speech, breathing, and swallowing by ensuring that the proper channels between the oral, pharyngeal, and nasal cavities are open or closed during these processes. The soft palate is made up of five muscles, which are:
- Musculus uvulae
- Tensor veli palatini
- Levator veli palatini
- Palatopharyngeus
- Palatoglossus
Four of these muscles are innervated by the pharyngeal plexus via the vagus nerve (CN X). The exception is the tensor veli palatini muscle, which is innervated by the medial pterygoid nerve (a branch of CN V3).
The tensor veli palatini muscle tenses the soft palate during swallowing, preventing food from entering the nasopharynx. The levator veli palatini muscle elevates the soft palate during swallowing, also preventing food from entering the nasopharynx. The palatopharyngeus muscle tenses the soft palate while elevating the pharynx during swallowing. The palatoglossus muscle depresses the soft palate, bringing its oral surface into contact with the root of the tongue and initiating the act of swallowing.

The levator veli palatini is a small muscle that helps to elevate the palate
The palate is the roof of the mouth, separating the oral and nasal cavities. It consists of a hard palate at the front and a soft palate at the back. The soft palate is a muscular flap that aids in speech, breathing, and swallowing. It is composed of five muscles, one of which is the levator veli palatini.
When the levator veli palatini contracts, it helps to elevate the soft palate. This is important during swallowing, as it closes off the nasal cavity and prevents food from entering the nasopharynx. It also plays a role in speech, as it helps to tense and elevate the soft palate, allowing for the production of certain velar sounds. Additionally, contraction of this muscle helps to open the eustachian tube and equalize middle ear pressure with ambient air pressure.
The levator veli palatini is innervated by nerves that originate in the vagus nerve, also known as cranial nerve X. It is a paired muscle, with one on each side of the palate, working together to elevate the palate and perform its various functions.
