The paired submandibular glands (historically known as submaxillary glands) are major salivary glands located beneath the floor of the mouth.In adult humans, they each weigh about 15 grams and contribute some 60–67% of unstimulated saliva secretion; on stimulation their contribution decreases in proportion as parotid gland secretion rises to 50%. [1]
The most usual source of the mucin spillage is the sublingual salivary gland, but ranulae may also arise from the submandibular duct or the minor salivary glands in the floor of the mouth. A cervical ranula occurs when the spilled mucin dissects its way through the mylohyoid muscle , [ 1 ] which separates the sublingual space from the ...
Sialadenitis (sialoadenitis) is inflammation of salivary glands, usually the major ones, the most common being the parotid gland, followed by submandibular and sublingual glands. [1] It should not be confused with sialadenosis (sialosis) which is a non-inflammatory enlargement of the major salivary glands. [2]
The inflammatory lesions in Küttner's tumor may occur on one side (unilateral) or both sides (bilateral), predominantly involving the submandibular gland, [3] but is also known to occur in other major and minor salivary glands, [4] including the parotid gland. [5] [6] Overall, salivary gland tumors are relatively rare, with approximately 2.5 ...
Sialodochitis (also termed ductal sialadenitis), [1] is inflammation of the duct system of a salivary gland. [2] This is compared to sialadenitis, which is inflammation of the gland parenchyma. [3] Sialodochitis may be associated with salivary duct strictures and salivary stones. [4] It is common in both the parotid glands and submandibular ...
The submandibular glands (previously known as submaxillary glands) are a pair of major salivary glands located beneath the lower jaws, superior to the digastric muscles. [6] The secretion produced is a mixture of both serous fluid and mucus, and enters the oral cavity via the submandibular duct or Wharton duct. [7]
Serous demilunes, also known as Crescents of Giannuzzi or Demilunes of Heidenhain, are cellular formations in the shape of a half-moon (hence the name "demilune") on the mixed submandibular and sublingual salivary glands. [1] Serous demilunes are the serous cells at the distal end of mucous acini, the secretory endpieces of certain salivary ...
Oral and maxillofacial pathology refers to the diseases of the mouth ("oral cavity" or "stoma"), jaws ("maxillae" or "gnath") and related structures such as salivary glands, temporomandibular joints, facial muscles and perioral skin (the skin around the mouth). [1] [2] The mouth is an important organ with many different functions. It is also ...
