Salivary Glands

Glandulae salivariae is the Latin pronunciation for Salivary Glands. Salivary Glands are Exocrine Glands (glands with ducts producing Saliva) of mammals. They also secrete an enzyme which breaks down Starch into Maltose known as Amylase.

Salivary Glands


ANATOMY

The gland is divided into lobules. At the Hilum (point of entry of blood vessels and nerves in an organ) blood vessels and nerves enter the glands. There are five Salivary glands which are as follows.

 

These are the pairs of major salivary glands of humans wrapped around Mandibular Ramus. These glands secrete saliva that help in the mastication and swallowing to begin digestion of starches. The secretions are commonly Serous and enter the Oral Cavity through Stensen Duct.

 

These are the pairs of Salivary glands beneath the lower jaws superior to Digastric Muscles. The secretions produced by these glands are both Serous and Mucus in nature which enter the Oral cavity through Submandibular or Wharton Duct. 70% of saliva is produced by these glands in Oral Cavity. These are located in superficial Cervical Region and feel like a round ball about two fingers above Adam’s Apple.

 

These Salivary glands are located inferior to tongue and anterior to Submandibular Glands. They produce secretions which are Mucous in nature. These glands unlike other two don’t have any Intercalated or Striated ducts.

 

  • Minor Salivary Glands

800 to 1000 Minor Salivary Glands are located throughout the Oral Cavity. They are Innervated by the Seventh Facial Nerve.

 

  • Von Ebner's Glands

These glands are situated on dorsal surface of tongue near Sulcus Terminalis. They help in perception of taste through secretions of digestive enzymes and proteins.

INNERVATION

Salivary Glands are innervated by both Sympathetic and Parasympathetic arms of Autonomic Nervous System either directly or indirectly.

 

DISEASES

Some of the diseases related to Salivary Glands are as follows.

  • Tumors of Salivary Glands

  • Salivary Duct Calculus causing blockage of ducts resulting in pain and swelling of gland.
