Anatomic Definitions 1 * Introduce Chapter 1 Goals The goals of this chapter are to introduce the systemic approach that this text takes toward the topic of anatomy and physiology, while keeping in focus the practice of the EMT-Paramedic in the field. This chapter introduces basic descriptive terms and the case study format that will be used in each chapter of the book. Key positional terms are discussed, as well as definitions of anatomy and physiology. Instructor Directions 1.Direct the students to review the case study in the chapter and discuss the questions that accompany it. 2.Introduce the key terms that are used in the chapter. 3.Assign the students, either in groups or individually, to prepare an example of how an understanding of this chapter will aid the EMT-Paramedic in his/her clinical practice in the field.
