 Viva Question and Answers related to Salivary glands

Here are 30 potential viva questions and answers related to salivary glands:

  • What are the major salivary glands in humans?

The major salivary glands are the parotid, submandibular, and sublingual glands.

  • Describe the location of the parotid glands.
  • The parotid glands are located near the ear, between the skin and the masseter muscle.
  • What is the primary function of salivary glands?
  • Salivary glands produce saliva, which aids in digestion by moistening food and initiating the breakdown of carbohydrates.
  • How is saliva production regulated?
  • Saliva production is regulated by the autonomic nervous system, with both parasympathetic and sympathetic stimulation playing roles.
  • What is the composition of saliva?
  • Explain the role of amylase in saliva.
  • Amylase in saliva helps break down complex carbohydrates into simpler sugars.
  • Which salivary gland is the largest?
  • The parotid gland is the largest salivary gland.
  • What is the duct through which saliva from the parotid gland enters the mouth?
  • Saliva from the parotid gland enters the mouth through Stensen’s duct.
  • Discuss the innervation of the salivary glands.
  • Salivary glands are innervated by both sympathetic and parasympathetic nerves. Parasympathetic stimulation increases saliva production, while sympathetic stimulation decreases it.
  1. What is the function of the submandibular gland?
  • The submandibular gland produces saliva rich in enzymes and mucus, contributing to the digestion process.
  1. Describe the location of the sublingual glands.
  • The sublingual glands are situated beneath the tongue.
  1. Which duct carries saliva from the submandibular gland to the mouth?
  • Saliva from the submandibular gland is carried to the mouth through Wharton’s duct.
  1. How does the secretion of saliva change during stress?
  • Stress activates the sympathetic nervous system, leading to decreased saliva production.
  1. What is the role of saliva in oral health?
  1. Explain the term “xerostomia.”
  • Xerostomia refers to the condition of dry mouth, often due to reduced saliva production.
  1. What are some common causes of salivary gland infections?
  • Common causes include bacterial infections, viral infections (such as mumps), and blockages in the salivary ducts.
  1. Discuss the role of saliva in taste perception.
  • Saliva dissolves food molecules, allowing taste receptors on the tongue to detect flavors.
  1. How is saliva involved in the initial digestion of food?
  1. What is sialography, and how is it used in the context of salivary glands?
  • Sialography is a radiographic imaging technique used to visualize the ducts and structures of the salivary glands.
  • How can salivary gland stones (sialolithiasis) affect saliva flow?
  • Salivary gland stones can block the ducts, leading to reduced or obstructed saliva flow.
  • Explain the role of saliva in the protection of oral mucosa.
  • Saliva provides a protective barrier for oral mucosa, helping to prevent dryness and irritation.
  • What are some symptoms of salivary gland disorders?
  • Symptoms may include swelling, pain, dry mouth, difficulty swallowing, and altered taste.
  • Discuss the impact of aging on salivary gland function.
  • How does the parasympathetic nervous system affect saliva composition?
  • Parasympathetic stimulation increases the production of watery saliva.
  • What is the role of the myoepithelial cells in salivary glands?
  • Myoepithelial cells contract to help expel saliva from the acinar cells into the ducts.
  • Can salivary gland tumors be benign?
  • Yes, salivary gland tumors can be either benign or malignant.
  • How is Sjögren’s syndrome related to salivary gland function?
  • Sjögren’s syndrome is an autoimmune disorder that can lead to reduced saliva production.
  • Discuss the importance of saliva in maintaining oral pH.
  • What role do salivary glands play in the defense against oral infections?
  • Saliva contains antibacterial substances that help protect against oral infections.
  • How can imaging techniques like ultrasound be used in assessing salivary gland disorders?
  • Ultrasound can be used to evaluate the size, structure, and abnormalities of the salivary glands and ducts.

These questions cover a range of topics related to salivary glands, from anatomy and function to common disorders and diagnostic techniques. Viva question and answers in dental caries
