Quiz on Salivary Glands

What are salivary glands?

• Thyroid glands

• Sweat glands

• Exocrine glands

• Endocrine glands

Answer explanation

Salivary glands are exocrine glands that produce saliva, which aids in digestion by breaking down food. They are not thyroid glands, sweat glands, or endocrine glands.

Which type of glands have ducts that collect their secretion and open into body cavities?

• Endocrine glands

• Exocrine glands

• Sweat glands

• Thyroid glands

Answer explanation

Exocrine glands have ducts that collect their secretion and open into body cavities, distinguishing them from endocrine glands which secrete hormones directly into the bloodstream.

Which type of glands lack ducts and release their product into interstitial spaces around the cells?

• Endocrine glands

• Exocrine glands

• Sweat glands

• Thyroid glands

Answer explanation

Endocrine glands lack ducts and release their product into interstitial spaces around the cells, making them the correct choice.

What is the function of Myoepithelial cells in salivary glands?

• Secrete enzymes

• Reduce luminal volume

• Produce saliva

• Accelerate initial flow of saliva

Answer explanation

Myoepithelial cells in salivary glands accelerate the initial flow of saliva, helping in the secretion process.

Which type of acini in salivary glands is protein-forming and has a spherical or rounded shape?

• Oncocytes

• Mixed acini

• Mucous acini

• Serous acini

Answer explanation

Serous acini are the type of acini in salivary glands that are protein-forming and have a spherical or rounded shape.

What is the function of the intercalated ducts in salivary glands?

• Secrete lactoferrin

• Reabsorb Na and Cl ions

• Convey saliva towards oral cavity

• Replace damaged cells

Answer explanation

The function of the intercalated ducts in salivary glands is to replace damaged cells.

The main function of salivary glands is to produce saliva, which helps in the initial digestion process by moistening food and aiding in swallowing.

What age-related change is commonly seen in salivary glands?

• Increase in salivary secretion

• Fatty degenerative change

• Increase in acini size

• Increase in oncocytes

Answer explanation

Fatty degenerative change is commonly seen in salivary glands as an age-related change.
