Orbits: Anatomy & Routine Projections - Video Lesson

Hey, everybody. Welcome to today's lesson on the gross anatomy in routine radiographic projections of the orbits. This essential topic forms the foundation for accurate imaging and diagnosis of conditions related to the orbits. In this lesson, we'll cover the anatomy of the orbits and routine projections for radiographs. Let's get started. Anatomical terms related to the orbits include optic foramen, small hole that allows for the passage of the optic nerve, optic canal, small canal the optic foramen opens into. Superior orbital fissure, allows transmission of four primary cranial nerves that control the movement of the eye and eyelid. Inferior orbital fissure, allows for transmission of the maxillary branch of cranial nerve five. And sphenoid strut, small root of bone that separates the superior orbital fissure from the optic canal. Now let's apply these terms to identify the corresponding anatomy.
