What does connective tissue consist of?
|
Individual cells scattered within an extracellular matrix
|
What is the extra-cellular matrix made of?
|
Various fibers suspended in a fluid known as ground substance
|
What does ground substance consisnt of
|
Water flycosaminoglycansproteoglycansglycoproteins
|
What helps Ground substance exist as either watery liquid or firm solid form
|
Chemical composition, amount of tension and temperature
|
What does the thixotropy describe
|
Ability of ground substance to become more liquid as a movement and temp of the tissue increases
|
What 3 fibers are suspended in the ground substance
|
Collagenreticularelastic
|
What shape is collagen fiber?
|
Long , straight, wound like a rope
|
What does the shape confer to the connective tissue?
|
Tensile strength and flexibility
|
Where are collagen fibers more abundant?
|
Tissues that require a strong resistance to force like ligaments and tendons
|
What shape are reticular fribers?
|
Thin and branch into tiny nets capable of resisting force in multiple directions
|
What can the reticular fibers do?
|
Help hold organs and support structures together
|
What protein is in elastic fiber?
|
Elastin
|
How does elastic fiber look?
|
Branched and wavy
|
Why are they in connective tissue?
|
So that the tissue can return to original shape after being stratched
|
What so firbroblasts do?
|
Produce and secrete proteins that make up the fibers in the extra-cellular matrix
