1. Anatomy Concepts Jeff Ericksen, MD Assistant Professor, Physical Medicine & Rehabilitation

2. Objectives Outline basic reference concepts in anatomy Review nomenclature & terminology Outline relationships of body regions Introduce function terms, human biomechanics terms

3. Human Anatomy: Many Levels to View Cellular Organ Organ system Region Whole body

4. Anatomy Levels Cellular Organ Organ system Regional Whole body

5. Anatomy Levels Cellular Organ Organ system Regional Whole body

6. Anatomy Levels Cellular Organ Organ system Regional Whole body

8. Anatomy Levels Cellular Organ Organ system Regional Whole body

10. The Human Body’s Jobs Reproduction Defense barrier –Skin & microbes –Bone, muscle and soft organs Input/output –Oxygen & fuel consumption, hydration –Waste elimination

11. The Human Body’s Jobs Movement & biomechanics –Muscles, connective tissues, skeleton, skin Art form?

12. Anatomic Position: Standard Reference Enables same perspective to view body in 3 dimensions

14. Anatomy Standards Planes of reference Positional relationships Movement definitions –Joint movements, limb movements, whole body movements

15. Sagittal planes

17. Coronal plane relationships

20. Abduction Adduction

22. Circumduction

23. Dorsiflexion Plantarflexion Inversion (supination) Eversion (pronation)

25. Abduction AdductionExtension Flexion

27. Body Regions To Study Head & neck Torso Upper limb Pelvis Lower limb

37. Structural Concepts Biologic design consists of balance between tension and compression structural elements in viruses, cells, organs and whole animals. –Tensegrity = tension integrity –Buckminster Fuller & geodesic domes.

38. Musculoskeletal System Tensile elements = muscles, ligaments, tendons, joint capsules, menisci, and fascia. Compression elements = bones.

39. Tensegrity Allows Torque Reduction
