Connective Tissue - Fibres Flashcards
How many different types of fibres are found in all connective tissue?
Three
List the three types of fibres in all connective tissue.
Collagen
Reticulin
Elastin
Write a note on collagen fibres
5
Most common fibres in connective tissue proper
Long, straight and unbranched
Strong and flexible
Resist force in one direction
For example, in tendons and ligaments
What is the most common fibre in connective tissue proper?
Collagen fibres
Give two examples of connective tissue where collagen fibres are present.
Tendons
Ligaments
Write a note on reticular fibres.
5
Network of interwoven fibres (stroma)
Strong and flexible
Resist force in many directions
Stabilize functional cells (parenchyma of the spleen) and structures
In sheaths/capsules around organs
What are reticular fibres made of?
Interwoven fibres called stroma
What is the role of reticular fibres?
They stabilize functional cells and structures
Give an example of a functional cell where reticular fibres are found.
Parenchyma of the spleen
Where are reticular fibres found in organs?
They are found in sheaths/capsules around organs
Write a note on elastic fibres
4
Contain elastin
Branched and wavy
Return to original length after stretching
E.g. elastic ligaments of vertebrae
What protein is found in elastic fibres?
Elastin
What happens to elastic fibres after stretching?
They return to original length
Give one place in the body where elastic fibres are present.
Elastic ligaments of vertebrae
Write a note on ground substance.
2
Is clear, colourless and viscous
Fills spaces between cells of CT and slows pathogen movement
