Ch 3: Terminology for Direction, Planes & Regions of the Body

About This Chapter

Watch video lessons to learn anatomical directional terminology as well as the human body's regions and planes. The quizzes that follow each lesson can help you determine your comprehension of these terms.

Terminology for Direction, Planes, & Regions of the Body - Chapter Summary and Learning Objectives

When studying human anatomy, it's important to have an understanding of how the body can be theoretically dissected into certain regions or planes. There are also several terms used to describe the body's relative positioning. Using this standard anatomical terminology ensures science and medical professionals are on the same page when describing parts of the human body. In this chapter, you'll study lessons about:

  • What terms to use to describe the location of something relative to the body's position
  • How to identify the human body's planes
  • What anatomical terms are used to describe vertebrates
  • Which parts make up the body's cavities
  • What regions are in the abdominal and thorax areas

Anatomical Directional Terminology: Anterior, Posterior and More

1. 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.

Anatomical Directional Terminology: Limbs, Hands & Feet

2. 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.

Anatomical Directional Terminology: Lateral, Medial & More

3. 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.

Planes of the Human Body: Definition, Anatomy & Diagram

4. 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.

Directional Terminology for Anatomy

5. Directional Terminology for Anatomy

This lesson seeks to cover several different terms used in directional terminology: ventral, dorsal, cranial, caudal, cephalic, and rostral. These anatomical terms are defined from a bipedal perspective.

Major Body Cavities: Medical Terminology

6. Major Body Cavities: Medical Terminology

Without its organs, your body is nothing but a collection of empty spaces called cavities. There are two major cavity regions with their own unique subdivisions, and they'll be defined here.

Diagnosis of Abdominal Pain: The Four Quadrants

7. Diagnosis of Abdominal Pain: The Four Quadrants

This lesson will discuss the major points of the four-quadrant approach to diagnosing abdominal pain. While every possible permutation of pain in the abdomen won't be covered, you will come out with a good understanding as to what a problem may be.

Nine Regions of the Abdomen: Medical Terms

8. Nine Regions of the Abdomen: Medical Terms

Like we can divide a city, state, or country, your abdomen can be divided into many different regions for the purposes of study, reference, and practice. We will define all nine of the abdominal regions in this lesson.

Regions of the Peritoneum: Medical Vocabulary

9. Regions of the Peritoneum: Medical Vocabulary

Inside of your abdomen are layers of membranes and different spaces with really weird names. We'll define many of them: peritoneum (including the visceral and parietal parts), retroperitoneum, and mesentery.
