What is the primary function of saliva in the mouth?

  1. Lubrication and moistening of the oral cavity

  2. Digestion of carbohydrates

  3. Neutralization of acids

  4. All of the above


Correct Option: D
Explanation:

Saliva performs multiple functions in the mouth, including lubrication, moistening, digestion of carbohydrates, and neutralization of acids.

Which salivary gland is located beneath the tongue and produces a viscous, mucin-rich saliva?

  1. Parotid gland

  2. Submandibular gland

  3. Sublingual gland

  4. Minor salivary glands


Correct Option: C
Explanation:

The sublingual gland is responsible for producing a viscous, mucin-rich saliva that contributes to the lubrication and protection of the oral mucosa.

Which salivary gland is the largest and produces a serous, watery saliva?

  1. Parotid gland

  2. Submandibular gland

  3. Sublingual gland

  4. Minor salivary glands


Correct Option: A
Explanation:

The parotid gland is the largest salivary gland and produces a serous, watery saliva that is rich in enzymes, including amylase and lipase.

What is the role of amylase in saliva?

  1. Digestion of proteins

  2. Digestion of carbohydrates

  3. Digestion of fats

  4. Neutralization of acids


Correct Option: B
Explanation:

Amylase is an enzyme present in saliva that breaks down carbohydrates, particularly starch, into smaller sugar molecules, initiating the process of carbohydrate digestion.

Which salivary gland is located below the mandible and produces a mixed saliva containing both serous and mucous components?

  1. Parotid gland

  2. Submandibular gland

  3. Sublingual gland

  4. Minor salivary glands


Correct Option: B
Explanation:

The submandibular gland produces a mixed saliva that contains both serous and mucous components, contributing to both lubrication and digestion in the mouth.

What is the function of lysozyme in saliva?

  1. Digestion of carbohydrates

  2. Neutralization of acids

  3. Antibacterial activity

  4. Lubrication of the oral cavity


Correct Option: C
Explanation:

Lysozyme is an enzyme present in saliva that possesses antibacterial properties, helping to protect the oral cavity from harmful microorganisms.

Which salivary gland is responsible for producing the majority of the saliva in the mouth?

  1. Parotid gland

  2. Submandibular gland

  3. Sublingual gland

  4. Minor salivary glands


Correct Option: A
Explanation:

The parotid gland is responsible for producing approximately 60-70% of the total saliva in the mouth.

What is the role of salivary mucins in saliva?

  1. Lubrication of the oral cavity

  2. Digestion of carbohydrates

  3. Neutralization of acids

  4. Antibacterial activity


Correct Option: A
Explanation:

Salivary mucins are responsible for lubricating the oral cavity, providing a protective coating over the oral mucosa and facilitating speech and swallowing.

Which salivary gland is located on the floor of the mouth and produces a saliva rich in bicarbonate ions?

  1. Parotid gland

  2. Submandibular gland

  3. Sublingual gland

  4. Minor salivary glands


Correct Option: B
Explanation:

The submandibular gland produces a saliva rich in bicarbonate ions, which helps to neutralize acids in the mouth and maintain a neutral pH.

What is the role of salivary calcium and phosphate ions in saliva?

  1. Digestion of carbohydrates

  2. Neutralization of acids

  3. Remineralization of teeth

  4. Lubrication of the oral cavity


Correct Option: C
Explanation:

Salivary calcium and phosphate ions play a crucial role in the remineralization of teeth, helping to repair and strengthen tooth enamel.

Which salivary gland is responsible for producing saliva that is high in immunoglobulin A (IgA)?

  1. Parotid gland

  2. Submandibular gland

  3. Sublingual gland

  4. Minor salivary glands


Correct Option: D
Explanation:

The minor salivary glands, particularly the labial and palatal glands, are responsible for producing saliva that is high in immunoglobulin A (IgA), an important antibody that helps protect the oral cavity from infections.

What is the role of salivary glands in taste perception?

  1. Production of saliva

  2. Detection of taste stimuli

  3. Lubrication of the oral cavity

  4. Neutralization of acids


Correct Option: B
Explanation:

Salivary glands play a role in taste perception by helping to dissolve and carry taste molecules to taste buds located on the tongue and other parts of the oral cavity.

Which salivary gland is located behind the mandible and produces a saliva rich in potassium and chloride ions?

  1. Parotid gland

  2. Submandibular gland

  3. Sublingual gland

  4. Minor salivary glands


Correct Option: A
Explanation:

The parotid gland produces a saliva rich in potassium and chloride ions, contributing to the electrolyte balance in the mouth.

What is the role of salivary glands in maintaining oral pH?

  1. Production of saliva

  2. Neutralization of acids

  3. Lubrication of the oral cavity

  4. Digestion of carbohydrates


Correct Option: B
Explanation:

Salivary glands help to maintain a neutral pH in the mouth by producing saliva that contains bicarbonate ions, which neutralize acids produced by bacteria and food.

Which salivary gland is responsible for producing saliva that is high in salivary amylase?

  1. Parotid gland

  2. Submandibular gland

  3. Sublingual gland

  4. Minor salivary glands


Correct Option: A
Explanation:

The parotid gland produces saliva that is high in salivary amylase, an enzyme that plays a crucial role in the digestion of carbohydrates.
