Term
Types of Connective Tissue
Definition
Connective tissue proper - Fat and fibrous tissues of ligaments, Cartilage, Bone, and Blood
Term
Functions of Connective Tissue
Definition
Bind and Support
Protection
Insulation
Transportation (Blood)
Term
Origin of Connective Tissue
Definition
Mesenchyme embryonic tissue
Term
Vascularity of Connective Tissue
Definition
varies widely
Term
Extracellular Matrix
Definition
Ground Substance (Interstitial Fluid)
Fibers
Cells

Nonliving Connective Tissue
Allows tissue to bear weight
withstand abouse no other tissue could tolerate
Term
Common Characteristics of Connective Tissue
Definition
1. Common Origin
2. Degrees of Vascularity
3. Extracellular Matrix
Term
Ground Substance
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
Cell Adhesion Proteins
Definition
Fibronectin and Laminin serve as glue that allows connective tissue cells to attach themselves to matrix elements
Term
2 Subclasses of Connective Tissue Proper
Definition
Loose Connective - Areolar, Adipose ,
Reticular
Dense Connective - Regular, Irregular
Elastic
Term
3 Types of Cartilage
Definition
Hyaline
Fibrocartilage
Elastic
Term
Types of Osseous (Bone)
Definition
Compact Bone
Spongy Bone
Term
Blood
Definition
Is a type of connective tissue (fluid-tissue) that transports 02 and C02, nutrients, hormones, and wastes
Term
3 types of Fibers
Definition
Collagen
Elastic
Reticular
Term
4 Types of cells
Definition
Fibroblast found in connective tissue proper
Chondroblast found in cartilage
Osteoblast found in bone
Hematopoietic Stem Cells found in blood
Term
Types of cells
Definition
Blast - immature - actively mitotic
Cyte - mature - maintain health of the matrix
Term
Tensile
Definition
Strongest of all fibers (stronger than steel)
Term
Collagen Fibers
Definition
called white fibers when fresh
Term
Elastic Fibers
Definition
Long thin fibers forming branching networks also called yellow fibers but have an orange appearance
Term
Reticular Fibers
Definition
Support small blood vessels and support soft tissue of organs
Abundant where connective tissue meets other tissue types
Term
Mucous Connective Tissue
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
Fascia
Definition
Bundles muscle fiber together
Term
Dense Irregular Connective Tissue
Definition
Skin or dermis
Runs on more than one plane
