Question

Which of the following divides nasal cavity?

• A. Hyaline cartilage
• B. Mesethmoid cartilage
• C. Ligamentum arteriosum
• D. Laryngopharynx

Hint:

The nasal septum has both bony and cartilaginous parts. The mesethmoid cartilage is the primary cartilaginous component dividing the nasal cavity.

Answer 1

The Correct Option is B

The nasal cavity is divided into two halves by the nasal septum. The anterior part of the nasal septum is made of cartilage, specifically the septal cartilage, which is part of the mesethmoid cartilage complex (derived from the ethmoid bone). The posterior part is bony. Mesethmoid cartilage is the correct term for the cartilaginous structure that forms a significant part of the nasal septum.
