| Compare strength and work done @ slow loading rate compared to fast? | Strength decreased by 20%, work done decreased by 30% |
| Function of a ligament | provides joint stability, guides smooth joint motion, limits range of motion |
| Function of a Tendon | Connects muscle to bone and transmits muscle force to the bone |
| How much strain can elastin sustain by itself? | 200% |
| How much strain do our tendons/ligaments noramlly experience? | 2-5% strain |
| How much stress do our tendons/ligaments normally experience? | less than 25-30% max (ultimates stress) |
| Ligaments | Connects bone to bone |
| Tendon | Connects muscle to bone |
| What % of tendons and ligaments is extracellular material? | 80% |
| What % tendons and ligamenst are cells (fibroblasts)? | 20% |
| What is the compostion of extracellular material? | 70% Water and 30% solids |
| What is the strength of collagen compared to bone? | 1/2 stress of cortical bone in tension; none in compression or shear |
| What is the strength of elastin compared to bone? | 1/10stress of cortical bone in tension; none in compression or shear |
| What is the tendon max stress at failure compared to muscle? | It is twice that of muscle |
| What makes up ground substance? | proteoglycan gel (PG's) |
| Whats the compostion of the solid portion of tendons and ligaments? | Collagen Fibers-%75, Elastin-15%, ground substance-10% |
| Whats the significance of the 4 zones of the bone junction? | The transition provides a stronger bond to the bone; distributes the stresses b/t tendon(or ligament) & bone |
