Which meatus contains the nasolacrimal duct?

  1. superior

  2. middle

  3. inferior

  4. posterior

The correct answer is: inferior

The nasolacrimal duct drains tears from the eyes into the nasal cavity. It opens into the inferior meatus of the nasal cavity, which makes option C the correct answer. Options A, B, and D are incorrect: - The superior meatus (Option A) drains the posterior ethmoidal sinus and the sphenoidal sinus. - The middle meatus (Option B) contains the openings of the frontal sinus, maxillary sinus, and anterior ethmoidal cells. - The posterior meatus (Option D) contains the opening of the nasopharynx.
