|
Term
| Define: Epitheleal Tissue and Locations |
|
Definition
- composed of layers of closely spaced cells that cover organ surfaces or form glands.
-protection, secretion and absorption
- epidermis, inner digestive track lining, liver and glands
|
|
|
Term
| Define Connective Tissue and locations |
|
Definition
- more matrix than cell voume
- for support binding, and protecting organs
- blood, lymph, cartilage, bones, tendons, ligaments |
|
|
Term
|
Definition
elongated excitable cells specialized for contraction

Term
| Types of connective tissue |
|
Definition
1. fibrous
2. cartilage
3. bone
4. blood
5. adipose |
|
|
Term
|
Definition
1. collagenous
2. elastic
3. reticular |
|
|
Term
| classification of fibrous connective tissue? |
|
Definition
dense- more fibers, less fibroblasts,
loose- areolar, reticular, adipose
- more ECM present |
|
|
Term
|
Definition
- chondroblasts- secrete matrix , surrounded by lacunae
lacunae- little cavities surrounding chondroblasts
chondrocytes- mature chondroblasts, surrounded by lacunae
