1. Anatomy & Physiology Study of human biology is divided into two primary areas.

2. 1. Anatomy - (Greek Ana = up, tome cutting) field of study that describe the A. Gross Anatomy - study of body structures that are B. Microanatomy - level only. Histology -. Histology -. C. Systematic Anatomy - Studies body structure (skeletal, muscular). D. Regional Anatomy - with in a given region (head, leg).

3. 2. Physiology - (Greek physio = nature, logic=study) 2. Physiology - (Greek physio = nature, logic=study) A. Human physiology – Study of specific A. Human physiology – Study of specific B. Cellular & Systemic Physiology – emphasizes B. Cellular & Systemic Physiology – emphasizes

4. Structural Levels of Organization Small (Simple) to Large (Complex) Small (Simple) to Large (Complex)

5. Organ Systems

6. Characteristics of Life 1. 2. Anabolism - build up Catabolism - break down 3.4.5. 6.

7. Homeostasis - Balance of Life Internal environment is to the world around itself.

8. Two types of Control 1. Negative feedback – 1. Negative feedback –.

9. Negative Feedback

10. 2. Positive feedback - rare in a healthy body because a change in normal state

11. Health & Disease Disease any reduction from the Acute – Chronic – Symptoms - sensations, dizziness, pain Diagnosis - identifying a disease from its symptoms

12. Classification of disease 1. Congenital - Can be inherited May cause death Ex. 2. Immunological – Defense reaction by white blood cells (WBC’s) Ex. 3. Metabolic May cause death trauma. Ex. 4. Neoplastic Ex.

13. Directional terms

14. Directions

16. Correct Anatomical Position 1. Facing a. 2. Palms a.b.

17. Body Planes (imaginary planes) 3 Basic Types Sagittal – Sagittal – Midsagittal - Midsagittal - Parasagittal - Parasagittal - 2. Frontal - 3. Horizontal – halves Cross Section (transverse).

19. The Body Plan

22. Body Parts & Regions

23. Body Cavities (Spaces) 2 Major 1. Dorsal Cavities 2. Ventral Cavities  - upper a.  Abdominal Pelvic Cavity a. b. separate the 2 cavities separate the 2 cavities

24. Body Cavities (Spaces) 2 Major 1. Dorsal Cavities  Cranial Cavity  Vertebrate Canal 2. Ventral Cavities  Thoracic - upper a. Pleural b. Pericardial  Abdominal Pelvic Cavity a. Abdominal cavity b. Pelvic Cavity Diaphragm separate the 2 cavities

25. Cavities are covered by membranes Serous Membrane –. a. Visceral – b. Parietal - c. usually fluid between the two to reduce friction by body movement.

26. Cavities are covered by membranes 2. - Surrounds the heart. 2. - Surrounds the heart. 3. – Covers the lungs. 3. – Covers the lungs. 4. – Lines the abdominolpelvic cavity. 4. – Lines the abdominolpelvic cavity. A. – fused peritoneum to support organs A. – fused peritoneum to support organs B. – behind the peritonium. B. – behind the peritonium.
