Intermediate Nasal Bone Quiz

Q1. Which four bones does each nasal bone typically articulate with?

• Frontal, maxilla, ethmoid, and opposite nasal bone
• Maxilla, zygomatic, palatine, and mandible
• Frontal, mandible, temporal, and vomer
• Ethmoid, sphenoid, occipital, and temporal

Q2. Which suture joins the right and left nasal bones at the midline?

• Internasal suture
• Coronal suture
• Lambdoid suture
• Squamous suture

Q3. Which suture joins the nasal bones to the frontal bone superiorly?

• Palatomaxillary suture
• Zygomaticomaxillary suture
• Frontonasal suture
• Internasal suture

Q4. Which cranial bone contributes to the posterior relationship of the nasal bones near their internal surfaces?

• Occipital bone
• Parietal bone
• Temporal bone
• Ethmoid bone

Q5. Which nerve is associated with a groove on the internal surface of the nasal bone?

• Anterior ethmoidal nerve
• Hypoglossal nerve
• Inferior alveolar nerve
• Greater auricular nerve

Q6. The anterior ethmoidal nerve is ultimately derived from which trigeminal division?

• Facial nerve, VII
• Ophthalmic division, V1
• Mandibular division, V3
• Maxillary division, V2

Q7. Which opening of the bony nasal skeleton lies inferior to the nasal bones?

• Foramen ovale
• Foramen magnum
• Jugular foramen
• Piriform aperture

Q8. How does the thickness of a nasal bone generally vary from superior to inferior?

• Hollow superiorly and solid inferiorly
• Thinner superiorly and thicker inferiorly in every case
• Thicker superiorly and thinner inferiorly
• Uniformly thick throughout

Q9. Which structure attaches near the inferior margin of the nasal bone to continue the framework of the nose?

• Lateral nasal cartilage
• Thyroid cartilage
• Auricular cartilage
• Articular disc of the TMJ

Q10. Why are the nasal bones considered part of the facial skeleton rather than the neurocranium?

• They contain the middle ear
• They surround the spinal cord
• They form part of the facial framework and external nose
• They form the posterior cranial fossa
