The ductus sublingualis major, also known as the greater sublingual duct, is a anatomical structure in the oral cavity that plays a crucial role in salivary gland function. It is a large excretory duct found in the sublingual gland, one of the major salivary glands located beneath the tongue.
The ductus sublingualis major carries saliva from the sublingual gland to the oral cavity, allowing for the release of saliva into the mouth. Saliva, a clear and watery fluid, serves various important functions in the oral cavity, such as lubricating the mouth, aiding in digestion, and maintaining oral hygiene by neutralizing acids and preventing the growth of bacteria.
The ductus sublingualis major, along with other salivary ducts, transports the saliva produced by the sublingual gland, which is responsible for producing around 5% of the total saliva in the mouth. The duct originates within the sublingual gland and extends through the sublingual glandular tissue, eventually opening into the mouth beneath the tongue.
Disorders affecting the ductus sublingualis major can lead to various oral health issues, such as dry mouth (xerostomia) or excessive saliva production (sialorrhea). Additionally, blockages or infections within the duct can cause pain, swelling, and inflammation in the area. Proper functioning of the duct is crucial for maintaining optimal oral health and ensuring the normal flow of saliva within the oral cavity.
