Common Characteristics of Connective Tissue |
|
Definition
1. Common Origin 2. Degrees of Vascularity 3. Extracellular Matrix |
|
|
Term
|
Definition
Unstructured material that fills the space between the cells and contains the fibers. It consists of interstitial fluid, cell adhesion proteins, and proteoglycans. |
|

Term
|
Definition
Fibronectin and Laminin serve as glue that allows connective tissue cells to attach themselves to matrix elements |

Definition
Fibroblast found in connective tissue proper Chondroblast found in cartilage Osteoblast found in bone Hematopoietic Stem Cells found in blood |

|
Definition
Blast - immature - actively mitotic Cyte - mature - maintain health of the matrix |

Definition
Strongest of all fibers (stronger than steel) |
|
|
Term
|
Definition
called white fibers when fresh |
|
|
Term
|
Definition
Long thin fibers forming branching networks also called yellow fibers but have an orange appearance |
|
|
Term
|
Definition
Support small blood vessels and support soft tissue of organs Abundant where connective tissue meets other tissue types |

Term
|
Definition
Supports the Umbilical Cord of the fetus |
|
|
Term
Dense Regular Connective Tissue |
|
Definition
Runs in one direction
Tendons - cords that attach tendon to bone or other muscle
Ligaments - Binds bones together at joint (has more elastin) |
|
|
Term
|
Definition
Bundles muscle fiber together |
|
|
Term
Dense Irregular Connective Tissue |
|
Definition
Skin or dermis Runs on more than one plane |
