Q1. Which two bones together form the lacrimal sac fossa?
- Ethmoid and sphenoid bones
- Mandible and maxilla
- Zygomatic and temporal bones
- Maxilla and lacrimal bone
Q2. Which structure forms the anterior boundary of the lacrimal sac fossa?
- Anterior lacrimal crest of the maxilla
- Posterior lacrimal crest of the lacrimal bone
- Crista galli of the ethmoid
- Inferior orbital fissure
Q3. Which structure forms the posterior boundary of the lacrimal sac fossa?
- Greater wing of the sphenoid
- Supraorbital margin
- Posterior lacrimal crest of the lacrimal bone
- Anterior lacrimal crest of the maxilla
Q4. Which duct continues inferiorly from the lacrimal sac?
- Parotid duct
- Nasolacrimal duct
- Submandibular duct
- Auditory tube
Q5. Where does the nasolacrimal duct ultimately open in the nasal cavity?
- Middle meatus
- Superior meatus
- Inferior meatus
- Sphenoethmoidal recess
Q6. Which four bones articulate directly with the lacrimal bone?
- Frontal, parietal, temporal, and occipital
- Frontal, ethmoid, maxilla, and inferior nasal concha
- Sphenoid, temporal, mandible, and nasal
- Maxilla, mandible, vomer, and zygomatic
Q7. Which neighboring bone forms most of the medial orbital wall posterior to the lacrimal bone?
- Temporal bone
- Occipital bone
- Mandible
- Ethmoid bone
Q8. Which neighboring structure articulates with the inferior part of the lacrimal bone and contributes to the lateral nasal wall?
- Vomer
- Inferior nasal concha
- Middle nasal concha
- Nasal septal cartilage
Q9. Why is the lacrimal bone described as one of the smallest facial bones?
- It is a small thin plate in the medial orbital wall
- It is a sesamoid bone within an eyelid
- It is confined to a tooth socket
- It is a tiny ossicle inside the middle ear
Q10. Which statement correctly relates the lacrimal bone to the orbit and nasal cavity?
- It links medial orbital anatomy with the nasolacrimal drainage pathway
- It forms the orbital floor and mandibular canal
- It forms the orbital roof and contains the frontal sinus
- It forms the lateral orbital rim and opens into the middle ear
