Connective tissue Flashcards
What are the components of extra cellular matrix of connective tissue
Collagen & elastin fibres
Ground substance
Water
Properties of loose connective tissue
Supports organs
Cells found in network of mostly collagen fibres
Fewer fibres than dense connective tissue
More cells & ground substance than DCT
Less rigid than DCT
Properties of regular dense connective tissue
Mainly type I collagen fibres
In areas where lots of tensile strength is required
Collagen fibres densely packed & arranged parallel to each other
Arrangement allows fibres to have good resistance to forces pulling along single axis
Properties of irregular dense connective tissue
Type I collagen fibres surrounded by some ground substance
Network of elastic fibres
Collagen fibres oriented randomly for strength
Can withstand force from different directions
Properties of lamellar bone tissue
Compact
Extracellular matrix around cells
Gives compact bone its hardness
Made of both organic & inorganic materials
3 types
What are the 3 types of lamellar bone tissue
Interstitial lamellae – fill spaces between osteons
Circumferential lamellae – wrap around circumference of entire bone
Concentric lamellae – arranged concentrically around central canal of each osteon
What are the properties of trabecular bone tissue
Spongy
Support & strength to bones
Highly porous
Organised into network of interconnected rods & plates (trabeculae) which surrounds pores
What are the properties of blood tissue
Fluid matrix (plasma)
No fibres
What are the properties of adipose tissue
Brown adipose tissue – heat
White adipose tissue – energy store
Little extra cellular matrix surrounding cells
Cells full of lipid
What is mesenchyme
Mesoderm produces mesenchyme
Loose connective tissue in embryo that gives rise to various structures (blood vessels, muscles, tendons & cartilage)
