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

2. Bell Work Define the following using your red book Superior inferior
Anterior
posterior
Medial
lateral
Proximal
Distal
Caudal
Cranial

3. Standard
Outline the gross normal structure and function of all body systems and summarize appropriate medical text(s) in order to relate signs and symptoms of common diseases and disorders associated with each.
integumentary and lymphatic systems
nervous and musculoskeletal systems
cardiovascular and respiratory systems
digestive and urinary systems
reproductive and endocrine systems

4. At the conclusion of this lesson I CAN:
Model the anatomical position
Differentiate between various directional terms and model their position
Identify the body cavity to which various organs are located

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
Figure 1.7a

7. 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
Superior
Upper or above
Cephalad or Cranial
Head
Caudal or Caudad
Tail, tail end
Anterior
Toward the front
Posterior
Toward the back
Dorsal
Ventral

10. Positions of the body
Prone: Position of lying on the anterior part of the body
Supine: Position of lying on the posterior part of the body.

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

15. 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

17. 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
