The submandibular salivary glands develop later than the parotid glands and appear late in the sixth week of prenatal development. They develop bilaterally from epithelial buds in the sulcus surrounding the sublingual folds on the floor of the primitive mouth. Solid cords branch from the buds and grow posteriorly, lateral to the developing tongue.
The two parotid glands are major salivary glands wrapped around the mandibular ramus in humans. [6] These are largest of the salivary glands, secreting saliva to facilitate mastication and swallowing, and amylase to begin the digestion of starches. [7] It is the serous type of gland which secretes alpha-amylase (also known as ptyalin). [8]
The parotid duct is formed when several interlobular ducts, the largest ducts inside the parotid gland, join.It emerges from the parotid gland. It runs forward along the lateral side of the masseter muscle for around 7 cm. [2] In this course, the duct is surrounded by the buccal fat pad.
Mucoepidermoid carcinoma is a common malignant tumour of the salivary glands and has a low incidence of 4–13%. [13] Adenoid cystic carcinoma is also a common malignant salivary gland lesion and has an incidence of 4–8%. This carcinoma tends to invade nerves and can re-occur post-treatment.
The submandibular duct (also Wharton's duct or historically submaxillary duct) is one of the salivary excretory ducts. It is about 5 cm long, and its wall is much thinner than that of the parotid duct. It drains saliva from each bilateral submandibular gland and sublingual gland to the sublingual caruncle in the floor of the mouth.
The sublingual salivary glands appear in the eighth week of prenatal development, two weeks later than the other two major salivary glands. They develop from epithelial buds in the sulcus surrounding the sublingual folds on the floor of the mouth, lateral to the developing submandibular gland. These buds branch and form into cords that canalize ...
