Between 64- 80% of all primary epithelial tumours occur in parotid glands, 7-11% occur in the submandibular glands, less than 1% occur in the sublingual glands
and 9-23% occur in the minor glands.
Two sublingual glands
(SLG) lie beneath the mucous membrane in the anterior part of floor of mouth under the tongue.
Age-related changes in human sublingual glands
: A post mortem study.
BPIFB1 was seen in early neural tissue and at later stages in submandibular and sublingual glands
. BPIFA1 is significantly expressed in early fetal oral tissue but BPIFB1 has extremely limited expression and the major salivary BPIF protein (BPIFA2) is not produced in fetal development.
Salivary flow is first derived by ionic exchanges by sodium/potassium bombs in acini and intercalated portions of secretory duct system , and in this study, we noticed that sodium/potassium-transporting ATPase subunit alpha-1 (P06685) was exclusive of control group in sublingual gland
, similarly to sodium channel subunit beta-3 (Q9JK00) and sodium/potassium-transporting ATPase subunit alpha-2 (P06686) that were unique of submandibular gland of animals not submitted to MeHg exposure.
Mucoceles are commonly associated with the sublingual gland
and develop at cerival, sublingual and pharyngeal areas (Brown, 1989; Waldron and Smith, 1991).
The digastric muscle was folded down for better visualization of the sublingual gland
and ducts and document the results with camera (Sony [alpha]200 10.2 mpx).
Thus the absence or paucity of striated ducts in the sublingual gland
helps to explain the tonicity of the saliva liberated by these glands7.
Ten percent occur in the parotid and the remaining 10% in the sublingual gland
and the minor salivar glands.1
For example, cystatin C is secreted by the submandibular gland, and musin MUC5B and calgranulin are secreted by the sublingual gland
If it is in the sublingual gland
, which is quite rare, it will present itself just behind the chin.
Other sites where it has been reported include nasal cavity, trachea, parotid gland, sublingual gland
, submandibular gland, larynx, buccal mucosa, maxillary sinus, tongue, tonsil, and retromolar trigone.
