Collagen molecules are secreted into the extracellular space, where they assemble spontaneously into cross-linked fibrils, which in turn are bundled together into the thick collagen fibers seen with a microscope. Extremely tough with high tensile strength because of the cross link. |
|
Definition
|
|
Term
- Long, thin elastic fibers form branching networks in the extracellular matrix. Contain rubberlike protein, elastin, that allows them to stretch and recoil like rubber bands. Can only stretch so much before it becomes taut, then when the tension eases the elastic fibers return to normal. Found in areas where greater elasticity is needed- skin, lungs, blood vessel walls. |

Definition
|
|
Term
Short, fine, collagenous fibers have a slightly different chemistry and form. Continuous with collagen fibers branching extensively and forming delicate networks that surround small blood vessels and support the soft tissue of organs.
