1. The Human Body: Anatomical Regions, Directions, and Body Cavities

2. Bell Work Define the following using your red book Superior inferior
Anterior

Medial
lateral
Proximal
Distal
Caudal
Cranial

3. Standard 12 and 13: Outline the in-depth normal structure and function
Outline the bony anatomy and organ structures of the
musculoskeletal,
digestive,
cardio-respiratory systems
specifically as they relate to radiology.
Review directions, planes, and sections of the body in order to perform radiographic images. Summarize appropriate medical text(s) in order to list signs and symptoms of common diseases and disorders associated with each system.

4. Objectives At the conclusion of this lesson I CAN:
Model the anatomical position
Differentiate between various directional terms and model their position
Identify the body planes

5. Why do we need to learn body directions?

6. Anatomical Position Body erect Feet slightly apart
Palms facing forward
Thumbs point away from body

8. Medial
Toward the midline of the body
Lateral
Away from the midline of the body
Proximal
Toward a reference point (extremity)
Distal
Away from a reference point (extremity)
Inferior
Lower or below

9. Directional Terms

10. Directional Terms
Table 1.1

12. PARTNERS 1 Lateral to the heart Proximal to the knee
Inferior to the neck
On the anterior side of the body
Distal to the elbow
Posterior side of the hand

13. Partners 2 Inferior to the heart Distal to the knee
On the posterior side of the neck
Medial to the lungs
Superior to the waist
On the anterior side of the arm

14. Body Planes Sagittal – divides the body into right and left parts
Frontal or coronal – divides the body into anterior and posterior parts
Transverse or horizontal (cross section) – divides the body into superior and inferior parts

16. Body Planes and Sections
The body may be sectioned (cut) along a flat surface called a plane.
The three most common planes are:
Sagittal (Median) plane
(cuts body into left & right)
Frontal (coronal) plane
(cuts body into front & back)
Transverse plane (cross section)
(cuts body into superior &
inferior parts)
Sagittal – think twins
