The two main types of fibers found in ligaments are:
- Collagen fibers: These make up the majority of a ligament and provide strength and resistance to stretching. Most ligament collagen is type I collagen.
- Elastin fibers: These are present in smaller amounts and give ligaments limited flexibility, allowing them to stretch slightly and return to their original shape.
Together, collagen and elastin help ligaments stabilize joints while permitting controlled movement.
