What is areolar tissue?
Tissue that is loosely organized fibers, abundant blood vessels, and a lot of seemingly empty space. Appearance can be quite variable
-
What is reticular tissue?
- -mesh of reticular fibers and fibroblast
- -forms supportive stroma (framework) for lymphatic organs
-
What is dense reqular connective tissue?
- collagen fibers (densely packed, parallel)
- -compressed fibroblast nuclie
- tendons attach muscles to bones and ligaments hold bones together
-
What is dense irregular connective tissue?
Collagen fibers (densely packed, randomly arranged) and few visable cells; withstands stress
-
What is apidose tissue?
- Empty looking cells with thin margins; nucleus pressed against cell membrane
- -energy storage, insulation, cushioning
-
What is cartilidge?
Supportive connective tissue with flexible, rubbery matrix; no blood vessels
-
What is hyaline cartilage?
- fine collagen fibers (matrix makes clear, glassy microscopic appearance)
- -eases joint movement, holds airway open, moves vocal cords
-
What is elastic cartilage
- cartilage containing large bundles of collagen fibers (without perichondruim)
- -resist compression and absorbs shock
-
What is bone?
- -organ of the body; multiple tissue types (femur, mandible)
- -bone tissues (osseous tissue)
-
What are two types of osseous tissue?
- Spongy bone-spongy in appearance
- -covered by compact bone
- Compact bone-denser calcified tissue with no visable spaces
-
What are osteocytes?
mature bone cells that occupy lucunae
-
Where is bone matrix deposited?
concentric lamella
-
What is canaliculi?
delicate canals that radiate from each lacuna; osteocytes communication
-
What is periosteum?
tough fibrous connective tissue covering of bone
-
What is blood? (connective aspect)
- -fluid connective tissue
- -transports cells and dissolved matter
- -plasma is blood's liquid ground substance
-
What elements do blood form?
- Erythrocytes-RBC
- -transports O2 and CO2Leukocytes-WBC
- -defense against infection
- Platelets-cell fragments
- -clotting
