|
fibers that are long, straight and very stong
|
|
|
elastic
|
connective tissue fibers that are stretchy
|
|
|
reticular

connective tissue fibers that form a network of thin fibers
|
|
|
connective tissue
|
establishing a structural framework, transporting fluids and dissolved material, protecting delicate organs, supporting, surrounding and interconnecting tissues, storing energy reserves, defending the body from microorganisms
|
|
|
extracellular matrix
|
-contains fibers which provide support
-contains material called ground substance which fills in all space between cells and fibers |
|
|
ground substance
|
binds water matrix (filler material)
|
|
|
connective tissue proper
|
found everywhere in the body
-contains varied cell populations -contains various fiber types a ground substance which is syrupy in consistency |
|
|
cartilage
|
small thin plates of solid material
matrix is a firm gel containing chondroitin sulfate |
|
|
perichondrium
|
separates cartilage from surrounding tissues and contains chondoblasts which produce new cartilage
|
|
|
lacunae (singular:lacuna)
|
small fluid-filled spaces within cartilage plate
|
|
|
progenitor cells/stem cells
|
---
|
|
|
appositional growth
|
immature chondrocytes (chondroblasts) in perichondrium produce new catilage along surface of mature catilage
-avascular |
|
|
interstitial growth
|
mature chondrocytes divide within the lacuae
-growth from inside |
|
|
List four functions of connective tissue
|
-establishing a structural framework (bones)
-transporting fluids and dissolved materials (blood) -protecting delicate organs -supporting,surrounding, and interconnecting tissues -storing energy reserves(fat/adipose tissue) -defending the body from microorganisms |
|
|
what is extracellular matrix?
|
fills space, so that cells are not right ip against their neighbors
|
