What is sublingual space?
The sublingual space is a part of the floor of mouth 1. As the sublingual space is not bounded by fascia posteriorly, some authors consider the sublingual space a component of the submandibular space 2. More commonly, however, the sublingual and submandibular spaces are discussed separately 3-5.
Where is the sublingual space located?
The sublingual space is located below the mouth and above the mylohyoid muscle and is part of the suprahyoid group of fascial spaces.
What are the contents of sublingual space?
This space contains the lingual artery and nerve, the hypoglossal nerve, the glossopharyngeal nerve, Wharton’s duct, and the sublingual salivary gland, which drains into the oral cavity through several small excretory ducts in the floor of the mouth and a major duct known as Bartholin’s duct.
What is the function of the sublingual?
The sublingual glands are considered mixed glands because they produce both mucus and serous fluid, a clear to pale yellow watery fluid that is found in the body. However, it primarily produces a thick mucus. It lubricates the tissues of your mouth, helps you digest food, and allows you to swallow it.
What is the space under the tongue called?
The lingual frenulum is a fold of mucus membrane that’s located under the center portion of your tongue.
What is submandibular space?
The submandibular space is a suprahyoid deep compartment of the head and neck that encompasses the submandibular gland and surrounding structures.
What is the region under the tongue called?
Below your tongue is a horseshoe-shaped area of tissue known as the floor of the mouth. This flat area of soft tissue has a separate rising fold of tissue that connects it to the underside of the tongue, known as the lingual frenulum.
What is the sublingual duct called?
duct of Rivinus
duct of Rivinus: the sublingual gland drains through numerous small ducts all of which open into the floor of the mouth and are collectively termed the duct of Rivinus; the largest is the major duct of the sublingual salivary gland called Bartholin duct.
What is the name for the space between the lips and the gingiva?
The tongue occupies the floor of the oral cavity. The oral cavity can be divided into two parts: (1) the oral vestibule, which is the space between the lips or cheeks and the teeth and (2) the oral cavity proper, the region medial to the teeth.
Where is submandibular space?
The submandibular space extends from the hyoid bone to the mucosa of the floor of the mouth, and is bound anteriorly and laterally by the mandible and inferiorly by the superficial layer of the deep cervical fascia.
What is a fascial space?
Fascial spaces (also termed fascial tissue spaces or tissue spaces) are potential spaces that exist between the fasciae and underlying organs and other tissues. In health, these spaces do not exist; they are only created by pathology, e.g. the spread of pus or cellulitis in an infection.
What is the sublingual space?
Jump to navigation Jump to search. Sublingual space. Sublingual space situated deep to mylohyoid muscle. Sublingual and submandibular space, coronal plane illustration and MRI. Anatomical terminology. The sublingual space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces).
What is the difference between platysma and sublingual space?
The platysma forms the superficial margin of the submandibular space ( arrowhead ). The sublingual space is a potential space without a fascial lining. The sublingual space is superomedial to the mylohyoid muscle and lateral to the genioglossus and geniohyoid muscles in the oral cavity.
What is the pathophysiology of the submandibular and sublingual spaces?
Although the submandibular and sublingual spaces are small, a wide range of pathologic processes may involve these spaces. They include cystic lesions, inflammatory conditions with various causes, rare vascular lesions, and benign and malignant neoplasms.
What is the sublingual space of the mylohyoid?
The sublingual space communicates posteriorly around the posterior free border of the mylohyoid muscle with the submandibular space. Infections of the sublingual space may also erode through the mylohyoid, or spread via the lymphatics to the submandibular and submental spaces .
