Question

Which of the following bone forms the inferior part of nasal septum?

• A. Ethmoid
• B. Vomer
• C. Girdle
• D. None of the above

Answer 1

The correct option is B Vomer

• The nasal septum is the thin wall of bone and cartilage that separates the right and left nostrils.
• The bones comprising the nasal septum include the maxillary crest, vomer and the perpendicular plate of the ethmoid.
• Vomer bone is thin and quadrilateral in shape.
• The vomer forms the inferior part of the nasal septum and the superior part is formed by the perpendicular plate of the ethmoid bone.
• Hence the bone which forms the inferior part of the nasal septum is vomer.
• So, the correct answer is vomer.
