Unit 1

1. Intro to Structure and Function Unit 1

2. Directional Orientation Guiding Questions: • What does directional orientation tell you about a patient? • Make a chart of the various directional orientation terms • Why would a veterinarian and a doctor have a disagreement about the words anterior, ventral, posterior, and dorsal?

3. Why get so technical? • Communicates precise information • Used in procedures, therapies

4. Directional Orientation Explains a particular view of a person/subject

5. Biped vs. Quadruped

6. Directional Planes Guiding Questions: • How are directional planes different from directional orientation terms? • Make a chart of the various directional planes terms

7. DirectionalPlanes “Midsagittal” Plane Views of imaginary lines sliced through a person/subject

8. Positions Guiding Questions: • What do position terms indicate? • Why do you think there are so many different positions?

9. Some Positional Examples • Dorsal recumbent • Knee-chest • Lithotomy • Sim’s • Sitting • Trendelenberg Mod.

10. Why so many positions to know? • Trendelenberg • Allows better access to the pelvic organs as gravity pulls the intestines away from the pelvis • Increases blood flow to the brain • Sitting • Examination of heart, lungs, head, eyes, ears, nose throat

11. More positions: • Fowler’s position • Promote drainage or ease breathing • Upper body may be reclined • Knee-chest position • Used for rectal and vaginal examinations and as treatment to bring uterus into normal position

12. Even more positions! • Dorsal recumbent • Vaginal examinations • Obstetrical forceps • Supine – • Palpating internal organs, • front of body

13. Almost done! • Prone • Used to examine spine and back, • legs • Sim’s • used for rectal examination, • treatments and enemas • Lithotomy • Examination of pelvic organs

14. A little practice… • Work through the different slides here
