Connective Tissue Flashcards
Where does connective tissue originate from?
Mesoderm; middle layer of embryonic germ layer
Functions of connective tissue?
Protect and support body
Help bind body together
Transports of water and ions
Immunity
The dental pulp is what form of connective tissue?
Loose areolar connective tissue
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?
Tendons and ligaments
What tissue would you find reticular fibres?
Lymphatic
What is extra cellular matrix also known as?
Ground substance
What is the function of extra cellular matrix in connective tissue?
Provides support for cells
Determines function
Maintains hydration and structural integrity
Components of connective tissue extra cellular matrix
Water
Glycosoaminoglycans
Proteoglycans
Glycoproteins
Which connective tissue classification is found under epidermis and around mucous membranes?
Loose areolar connective tissue
Which connective tissue classification provides a supportive frame in semi sold matrix?
Reticular loose connective tissue
Which connect tissue classification is found in lymphatic organs and bone marrow?
Loose reticular connective tissue
What is the function of adipose loose connective tissue?
White adipose tissue supports thermally and where energy is stored. 20-25% body weight.
Brown adipose tissue generate heat from fat storage and helps burn calories.
What fibres are present in dense irregular connective tissue?
Collagenous and elastic
Properties of elastic fibres?
Able to stretch and recoil to original shape
Where is dense elastic connective tissue found?
Arteries and bronchi tubules
Which connective tissue is found in the dermis of skin?
Dense irregular connective tissue
Structure and function of dense regular connective tissue
Regular pattern, parallel densely packed collagen fibres
Resist force in 1 direction
Structure, function and location of areolar connective tissue
Collagen and elastic fibres in loose network.
Anchors, binds and supports organs.
Surround muscle fibres and blood vessels, under epidermis and mucous membranes.
2 types of specialised connective tissue
Supporting connective tissue
Fluid connective tissue
2 types of connective tissue proper
Dense connective tissue
Loose connective tissue
What are the supporting connective tissues?
Bone
Cartilage (elastic, hyaline, fibrocartilage)
