1. Body Cuts, Planes, Cavities, and Membranes

2. What is Anatomy? Literally means to cut apart
The study of internal and external structures of plants and animals

3. Two Types of Anatomy Microscopic Anatomy
Macroscopic Anatomy aka Gross Anatomy

4. Would the following items fall under Microscopic or Macroscopic Anatomy?
Stomach Bacteria
Red Blood Cell
Lungs
Femur
Cardiac Muscle Tissue
Ear

5. What is Physiology?
The study of how body parts function

6. How does anatomy relate to physiology?

7. Structure (anatomy) determines function (physiology)
If the structure is not right, the function can’t be right either.
Abnormal structure and function = disease
Example: Sickle Cell

8. Body Positions

9. Anatomical Position

10. Supine Position

11. Prone Position

12. Fowler’s Position

13. Body Cavities - Dorsal = Vertebral + Cranial - Ventral = Thoracic + Abdominal + Pelvic - Thoracic = Superior Mediastinum + Pleural + Pericardial

14. Body Planes

15. Body Membranes Thin, sheet-like structure
Functions in one of the following:
Covers and protects the body
Lines body cavities
Covers the internal surfaces of hollow organs

16. Epithelial Membranes
Cutaneous Membrane – covers body surfaces exposed to external environment
Ex: Skin
Serous Membranes – lines cavities that are not open to the external environment
Ex: Pleura
Mucous Membranes – lines body surfaces that open directly to the exterior
Ex: Digestive system

17. Connective Membranes
Synovial Membrane – lines joint cavities and helps cushion joints
