Soft Tissue Functions

deformation
fatigue resistance
tear/fracture resistance

Crimping: part of stress strain curve occurs in “toe region” with no tension. This occurs in collagen dense tissues. What is the purpose of this???

building blocks of soft tissue

Collagen:
- tensile strength
Elastin:
- tissue extensibility
Proteoglycans & glycosamino-glycans:
- allows cartilage to take on compressive load without fracturing

Multi-level structure: alter material properties of a tissue, add strenght, hard to create synthetically

    C --> D(fiber);

isotropy: homogeneity in all directions

Anisotropic tissues different physical properties along differenc axes.

why is collagen more organized in ligaments than tendons?

Do collagen fibers have “cross-bridges”???
