Submandibular gland histology

Unlike the parotid gland, the submandibular and sublingual glands possess both mucous and serous secretory cells. Slides 183-2 (submandibular) and 185A (sublingual) are stained with mucicarmine, which specifically stains mucus red. Survey the two alternate slides to compare the relative proportions of mucous acini in these two glands This is a low power image of a section through the human submandibular gland.

The submandibular glands lied superficial to the suprahyoid, and infrahyoid muscle groups, and were covered by the inferior portion of the parotid gland. The submandibular glands were characterized by a mixed parenchyma of mucous and serous secretory acini. Alcian blue (AB) staining and periodic acid-Schiff (PAS) reactions demonstrated that minipig submandibular glands synthesized and secreted acid mucous substances by serous cells and polysaccharide, and neutral mucous substances, by mucous.

  1. The paired submandibular glands (historically known as submaxillary glands) are major salivary glands located beneath the floor of the mouth. They each weigh about 15 grams and contribute some 60-67% of unstimulated saliva secretion; on stimulation their contribution decreases in proportion as the parotid secretion rises to 50%. [1
  2. Each submandibular gland is compound tubuloacinar, with serous acini more numerous than mucous tubules. Submandibular glands lie in the floor of the mouth and their excretory ducts empty just lateral to the frenulum of the tongue. Intralobular ducts are less numerous than in the parotid, but are still common. 40
  3. Normal Histology. Normal submandibular salivary gland is shown at medium power, with both serous and mucinous acini. The serous cells contain dark granules from which enzymes such as amylase and maltase are released. The mucinous cells contain pale mucin. The secretions drain into ducts
  4. The submandibular gland possesses both serous acini and mucous tubules. The tubules are pale staining and the cells secrete mucus. Acini stain more intensely because of the numerous secretory granules they contain. An intercalated duct with a simple cuboidal epithelium and a striated duct with a simple columnar epithelium are present. 200

Submandibular Gland. The submandibular gland is composed of both serous acini and mucous cells, and secretes saliva that contains more mucous than that of the parotid.

Lying superior to the digastric muscles, each submandibular gland is divided into superficial and deep lobes, which are separated by the mylohyoid muscle.. The superficial portion is larger The sublingual gland lies beneath the mucous membrane of the floor of the mouth, in contact with the sublingual fossa of the mandible, and is surrounded by loose connective tissue. Like the submandibular gland it is a mixed seromucinous gland but is predominantly mucous in contrast to the submandibular gland that is predominantly serous The submandibular gland sections obtained from the control group I of the male albino rats showed normal architecture in both the secretory end pieces and the duct system where the acini appeared normal in shape of mixed type (mainly serous with some mucous cells) and the intercalated and striated ducts revealed normal and intact epithelial lining while the mucus glands will help produce mucin that will lubricate the digestive tract. This study, for the first time documents the normal histology of submandibular salivary gland in this species, hence filling the knowledge gap that will help further research especially on the role of myoepihelial cells in the secretory glands tumours

Function. The submandibular gland produces saliva, which moistens the mouth and aids in chewing, swallowing, digestion, and helps to keep the mouth and teeth clean. Unstimulated, the submandibular glands provide the majority of saliva to the mouth. On stimulation, the parotid gland takes over, producing the majority of saliva The parotid and the principal and accessory submandibular glands of the little brown bat, Myotis lucifugus (Vespertilionidae), were examined using light microscopy and staining methods for mucosubstances.

Saliva is a fluid secreted by the salivary glands that keeps the oral cavity moist and also coats the teeth along with mucosa. The salivary gland possesses tubuloacinar units, and these are merocrine. The functional unit of the salivary glands is the terminal secretory piece called acini with a roughly spherical or tubular shape. It also consists of branched ducts for the passage of the saliva. Case Discussion. Pleomorphic adenomas of the salivary glands, also known as benign mixed tumors, are the most common salivary gland tumors.. On CT, when small, they have homogeneous attenuation and prominent enhancement. When larger, they can be heterogeneous with less prominent enhancement, foci of necrosis, and possible delayed enhancement Together, the salivary glands produce 1-1.5 L of saliva per day. About 45% is produced by the parotid gland, 45% by the submandibular glands, and 5% each by the sublingual and minor salivary glands.
