question 7
what structure is a cluster of lymphoid tissue located behind the
palatoglossal and palatopharyngeal arches that protects the pharynx?
gingivae
palatine tonsil
fauces
uvula

Explanation:

• Gingivae: These are the gums, not a cluster of lymphoid tissue.
• Palatine tonsil: Located in the lateral wall of the oropharynx, between the palatoglossal and palatopharyngeal arches. They are a cluster of lymphoid tissue that helps protect the pharynx from pathogens.
• Fauces: This is the passage from the mouth to the pharynx, not a lymphoid tissue structure.
• Uvula: A fleshy extension at the back of the soft palate, not lymphoid tissue.

Answer:

Palatine tonsil
