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 structures are in the 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 separates sublingual and submandibular space?
The mylohyoid muscle ( arrows ) separates the sublingual space from the submandibular space and is a key landmark in imaging of the oral cavity.
What is the sublingual area?
The sublingual gland is the smallest of the three major salivary glands [1], which also include the parotid and submandibular glands. The sublingual gland lies between the muscles of the floor of the oral cavity, which include the geniohyoid muscle, hyoglossus muscle medially, and the mylohyoid muscle inferiorly.
What is the submandibular space?
The submandibular space is a suprahyoid deep compartment of the head and neck that encompasses the submandibular gland and surrounding structures.
How many sublingual ducts are there?
The sublingual glands are drained by 8-20 excretory ducts called the ducts of Rivinus. The largest of all, the sublingual duct (of Bartholin) joins the submandibular duct to drain through the sublingual caruncle.
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.
Is submaxillary and submandibular space same?
Some also subsume the submental space and others further include the sublingual space, as these spaces communicate freely 5,6. In the latter case, the portion of the submandibular space inferior to the mylohyoid muscle sling is also known as the submaxillary space or submylohyoid space 6.
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.
Which duct ends in the sublingual caruncles?
submandibular ducts
The submandibular ducts drain saliva from the submandibular gland, and the sublingual glands to the sublingual caruncles at the base of the tongue.
What is the sublingual sulcus?
The sublingual space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space located below the mouth and above the mylohyoid muscle, and is part of the suprahyoid group of fascial spaces.
What is Submaxillary space?
The submandibular space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space, and is paired on either side, located on the superficial surface of the mylohyoid muscle between the anterior and posterior bellies of the digastric muscle.
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.
Why is it called Wharton’s duct?
Why Is It Called a Wharton’s Duct? Much like other parts of the body, these structures were named after the scientist who located them. According to A Biographical History of Endocrinology, Thomas Wharton (1614-1673) was an English scientist who studied various glands of the body.
