Mastering Directional Terms in Anatomy

Dr. Morton reviews directional terms in anatomy, providing practice questions and explanations. The video covers the use of directional terms to describe anatomical positions, such as the nose being inferior and medial to the eyes, and the ears being lateral and posterior to the nose. It also includes exercises on naming alveolar nerves and identifying cerebral arteries. The video concludes with a review of anatomical structures and their identification using directional terms.

What is the primary purpose of using directional terms in anatomy?
