The term "coronal" refers to anything related to a crown or a circular structure. In anatomy, it often describes the coronal plane, which divides the body into front (anterior) and back (posterior) sections. This plane is essential in medical imaging and surgical procedures, helping professionals understand the body's orientation. In astronomy, "coronal" pertains to the corona, the outer atmosphere of a star, particularly the Sun. The corona is visible during a total solar eclipse and is characterized by its high temperature and unique plasma structures. Understanding the corona is crucial for studying solar activity and its effects on Earth.
