  1. Who Is Greatest Scientist Of All Time?

  2. Isaac Newton • “The Father of Modern Science and Mathematics”

  3. “Newtonian” Principles • 1) Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. (Galileo) • 2) The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. (Aristotle) • 3) For every action there is an equal and opposite reaction (Kepler)

  4. PHYSIOLOGY “The logical assessment of the physics of the body’s systems”

  5. “Truth Is Ever To Be Found In The Simplicity and Not In The Multiplicity and Confusion of Things”

  6. Skeletomuscular Anatomy

  7. Is A Skeleton Necessary?

  8. Pro: Strength Protection Simplicity Con: Growth Mobility Pro: Growth Mobility Con: Strength Protection Large # of Different Tissues Required Exo- v. Endoskeleton

  9. Multiple Systemic Functions of Endoskeleton • Skeletal = Support • Muscular= Movement • Circulatory = RBC • Immune = WBC • Excretory = Storage of waste cations

  10. Skeletal Tissues • Cartilage • Chrondrocytes • Intracellular Matrix • Bone • Periosteum • Osteocytes • Marrow

  11. Ossification Of Cartilage • Chrondrocytesdeposit calcium salts into matrix • Control of this process by the endocrine system

  12. Why Doesn’t All Cartilage Ossify?

  13. Structure of Bone

  14. Periosteum • Fibrous sheath covering all parts of bone except for articular ends of joints

  15. Osteocytes • Bone cells • Can build up OR break down the matrix around them

  16. Osteon • Osteon = Osteocytes are arranged in concentric circles • Haversian canal = large central blood vessel • Canaliculi = small “canals”/cracks in matrix allowing for diffusion

  17. Spongy v. Compact Bone • Spongy Bone = lower density bone tissue located in the ends of long bones • Compact Bone = high density bone tissue in middle of bones

  18. Marrows RED Found in spongy bone at ends of long bones. Produces RBC YELLOW Found in middle of long bones Fatty tissue that may produce WBC (and RBC when needed)

  19. AXIAL Protection of vital organs Support v. gravity APPENDICULAR Articulated motion via anchorage points of muscles Axial v. Appendicular Endoskeleton

  20. How Does The Form Of Muscle Tissue Exemplify Its Function?

  21. Multiple Levels Of Muscle Organization • 630+ Muscles (varies on individual & sex) • 40% of body mass • Organ Level • Fiber (cellular level) • Myofibrils • Myofilaments • Actin (thin) • Myosin (thick)

  22. How Does Muscle Contract?

  23. Antagonistic Muscle Pairs

  24. Origin v. Insertion
