5 Basic Functions of Life A. Reproduction B.Responsiveness C. Growth D.Movement and Metabolism What is anatomy? It is the study of the internal and external structure of the body, and the physical relationships among body parts The Science of Anatomy and Physiology
What is Physiology? • It is the study of how living organisms perform their vital functions
Considers the unseen Divided into two areas A. Cytology-study of cells B. Histology-study of tissues Gross anatomy-the seen A. Surface anatomy-form and superficial marking B. Regional anatomy C. Systemic anatomy-OS Microscopic vs Macroscopic
Human Physiology • 4 areas • A. Cell physiology • B. Special physiology • C. System physiology • D. Pathological physiology or pathology
6 levels A. Chemical or Molecular level B. Cellular level C. Tissue level D. Organ level E. Organ system level F. Organism level Levels of Organization
Organ System • 11 organ systems • You will need to know the name of the organ system, the major function and the amount of organs in the system
Integumentary system • Protection from environment and temperature control • 5 organs
Muscular System • Locomotion, • Support • Heat production • 1 organ
Skeletal System • Support • Protection • Makes blood cells • 2 organs
Nervous System • Directing immediate response to stimuli • 2 organs
Endocrine Systems • Directing long term changes to other organ systems • 9 organs
Cardiovascular System • Internal transport of cells • 3 organs
Lymphatic System • Defense against infection and disease • 4 organs
Respiratory system • Delivery of air to sites where gas exchange can occur • 6 organs
Digestive System • Processing of food and absorption of nutrients, minerals, vitamins, and water • 9 organs
Urinary System • Elimination of excess water, cells, and waste products • 4 organs
Male Reproductive System • Production of sex cells and hormones • 3 organs
Female Reproductive System • Production of sex cells and hormones • 6 organs
Language of Anatomy • Surface Anatomy • Supine vs Prone
Regions of the Human Body • Table 1-1
1. Anterior 2. Ventral 3. Posterior 4. Dorsal 5. Cranial or Cephalic 6. Superior 1. The front; before 2. The belly side = anterior 3. The back;behind 4. The back= posterior 5. The head 6. Above; at the highest level Directional Terms of the Body
7. Caudal 8. Inferior 9. Medial 10. Lateral 7. The tail 8. Below: at a lower level 9. Toward the body’s longitudinal axis 10. Away from the body’s longitudinal axis Directional Terms (cont)
11. Proximal 12. Distal 13. Superficial 14. Deep 11. Toward an attached base 12. Away from an attached base 13. At, near or relatively close to the body surface 14. Farther from body surface Directional Terms (cont)
Anatomical regions • 4 abdominal pelvic quadrants • URQ • LRQ • ULQ • LRQ
Sectional Anatomy • Transverse plane- lies at right angles to the long axis of the body dividing it into superior and inferior sections aka horizontal section or a cross section. • Frontal plane- aka coronal plane parallels the long axis of the body divides body into anterior and posterior sections
Sectional Anatomy • Saggital plane- divides body into left and right sections also parallels the long axis of the body
Body Cavities • Two functions • Dorsal body cavities- cranium(cranial cavity) and spinal cord (spinal cavity • Ventral body cavities- 2 parts
