Nasal Bones: Anatomy & Routine Projections - Video Lesson

Hey, everybody. Welcome to today's lesson on the gross anatomy and routine radiographic projections of the nasal bones. In this lesson, we'll cover the anatomy and routine projections for radiographs. Let's get started. Much of the nose is made up of cartilage, with only two small, thin bones creating the bridge of the nose. The two fused nasal bones form the superior bony wall of the nasal cavity or bridge of the nose and vary in size and shape. The nasal bones lie anterior and supramedial to the frontal process of the maxillae and inferior to the frontal bone. The point of junction of the nasal bones with the frontal bone is a surface landmark called the nasion. Each nasal bone articulates with two cranial bones, the frontal bone superiorly and ethmoid bone posteriorly, and two facial bones, the maxillolaterally and the opposite nasal bone medially. There are also three sutures associated with the nasal bones. The frontonasal suture at the juncture
