What type of bone is the nasal bone?

Gross Anatomy The nasal bones are two small, symmetrical oblong bones, each having two surfaces and four borders. Positioned in the midface, at their junction, they form the bridge of the nose superiorly and anchor the upper lateral nasal cartilages inferiorly.

What is the nasal sinus?

The sinuses are four paired cavities (spaces) in the head. They are connected by narrow channels. The sinuses make thin mucus that drains out of the channels of the nose. This drainage helps keep the nose clean and free of bacteria. Normally filled with air, the sinuses can get blocked and filled with fluid.
