What cells produce fibres in connective tissue?
Fibroblasts
What are the main components of connective tissue?
- Cells
- Fibres
- Extracellular matrix
What types of fibres are components of connective tissue and there properties?
- Collagen; thickest and strongest, provides strength and resistance
- Reticular; randomly orientated collagenous fibres, cross link to form mesh work
- Elastic; contains elastin, returns to original state after being stretched
What tissue would you find dense collagen fibres?

What is the function of adipose loose connective tissue?
White adipose tissue supports thermally and where energy is stored. 20-25% body weight.
