Answer explanation

The function of the oral mucosa is to protect the underlying structures of the oral cavity.

Where are the taste buds located in the tongue?

• In the foliate papillae

• In the circumvallate papillae

• In the fungiform papillae

• In the filiform papillae

Answer explanation

Taste buds are located in the circumvallate papillae on the tongue.

What is the function of the circumvallate papillae?

• To sense salty taste

• To sense sweet taste

• To sense sour taste

• To sense bitter taste

Answer explanation

The function of the circumvallate papillae is to sense bitter taste.

What is the main difference between keratinized and non-keratinized oral epithelium?

• Presence of melanocytes

• Presence of desmosomes

• Presence of Langerhans cells

• Presence of tonofilaments

Answer explanation

The main difference between keratinized and non-keratinized oral epithelium is the presence of tonofilaments.

Where is the lingual tonsil located?

• In the anterior 2/3 of the tongue

• In the posterior 1/3 of the tongue

• On the lateral borders of the tongue

• On the tip of the tongue

Answer explanation

The lingual tonsil is located in the posterior 1/3 of the tongue, not in the anterior 2/3 or on the lateral borders or tip of the tongue.

What is the function of the attachment epithelium at the dento-gingival junction?

• To provide taste sensation

• To secrete saliva

• To attach the gingiva to the tooth structure

• To regulate body temperature

Answer explanation

The function of the attachment epithelium at the dento-gingival junction is to attach the gingiva to the tooth structure.

Which type of papillae are responsible for sweet and salty taste sensations?

• Foliate papillae

• Circumvallate papillae

• Fungiform papillae

• Filiform papillae

Answer explanation

Fungiform papillae are responsible for sweet and salty taste sensations.

What is the main function of the gingival ligament?

• To regulate body temperature

• To aid in taste sensation

• To strengthen the attachment of the gingiva to the tooth structure

• To provide structural support to the tongue

Answer explanation

The main function of the gingival ligament is to strengthen the attachment of the gingiva to the tooth structure.

What is the primary role of the neuroepithelial cells in taste buds?

• To provide structural support

• To carry taste sensation to the brain

• To secrete saliva

• To regulate body temperature

Answer explanation

Neuroepithelial cells in taste buds carry taste sensation to the brain, allowing us to perceive different flavors.

Where are the Von Ebner salivary glands located?

• In the circumvallate papillae

• In the fungiform papillae

• In the filiform papillae

• In the foliate papillae

Answer explanation

The Von Ebner salivary glands are located in the circumvallate papillae.
