About This Chapter
Anatomy and Physiology Overview - Chapter Summary
Those studying anatomy need to possess an understanding of the structure of living organisms and the human body. This chapter can help you gain that understanding, as these lessons cover an overview of anatomy and physiology.
Each of these lessons has been carefully designed by our team of experts, who possess extensive experience in their fields of expertise. Our instructors make sure that you have access to the most accurate and up-to-date information about these biology topics. Furthermore, our instructors can answer any of your questions on these topics.
Once you finish reviewing information in this chapter, you will have the ability to:
- Explain the primary structures and functions of the human body, including organ systems
- Define homeostasis and its role in the human body
- Identify anatomical directional terminology for different parts of the body
- Understand diagrams that illustrate the anatomical planes of the human body
1. Basic Structures & Functions of the Human Body
The human body is a complex system with structures ranging from cells to organ systems and functions ranging from waste removal to protection and defense. The structures and functions are dedicated to maintaining a state of health in the body.
2. Levels of Structural Organization in the Human Body
Explore the structural organization of the human body, starting at the level of the organism and progressing down in complexity through the organ system, organ, tissue, and cellular levels. Major features of each level are discussed.
3. What Is an Organ System? - Definition & Pictures
In this lesson, you will learn what an organ system is, and you will review each organ system in the human body. This will aid in your study of human anatomy and physiology. At the end of the lesson, a quiz will test your knowledge.
4. Homeostasis in the Human Body
Homeostasis is the term we use to describe the reasonably stable internal environment of your body. Learn how parts of your body communicate with each other to maintain this state of homeostasis, and how negative feedback loops work.
5. Anatomical Directional Terminology: Anterior, Posterior and More
Find out how to properly refer to the location of things at the front and back of a person as well as above or below a certain point on the body by learning the terms anterior, posterior, superior, and inferior.
6. Anatomical Directional Terminology: Limbs, Hands & Feet
In this lesson, you'll learn how we term the different sides of our feet and hands thanks to words like dorsal, plantar and palmar. You'll also learn how we name something that is near or far away from the trunk of our body thanks to words like proximal and distal.
7. Anatomical Directional Terminology: Lateral, Medial & More
Learn what it means to be on the same side as something else or on a different side altogether. In addition, find out what it means to be closer to or farther away from the middle of something as we explore the following terms: lateral, medial, ipsilateral, and contralateral.
8. Planes of the Human Body: Definition, Anatomy & Diagram
Learn about the different ways in which your body can be divided or cut up for theoretical and practical purposes as we explore the sagittal plane, transverse plane and coronal plane.
