The Cell and Connective Tissue Flashcards
What is the role of connective tissue?
- Binds structures together
- Forms a framework and support
What makes up the matrix in connective tissue?
- Specialised cells
- Extra cellular protein fibres
- Ground substance
Name the most important cell type in connective tissue
Fibroblasts
What extra cellular protein fibres are in connective tissue?
- Collagen
- Elastic fibres
- Reticular fibres
Describe collagen?
long straight fibres which are unbranched and rope-like. It’s flexable but very strong
What types of connective tissue are there?
- Connective tissue proper
- Loose
- Dense
- Fluid connective tissue
- Supportive connective tissue
Name the 3 characteristics of connective tissue proper
- Provide packing
- Able to stretch
- strong and able to stabalise
Describe loose connective tissue
- Packing material
- Fills spaces between organs
- cushions and stabalises specialised cells in organs
- supports epithelia
- surrounds and supports blood vessels and nerves
- store lipids
- provide a route for diffusion of materials
What type of loose conective tissus is VERY important?
Areolar
Describe dense connective tissue
- dominated by collagewn fibres
- scattered fibroblasts
Name the 3 types of membranes highlighted
- Mucous
- Serous
- Synovial
What type of connective tissue forms mucous and serous membranes?
Areolar
What type of epithelial cells make up the epithelial layer of mucous and serous membranes?
Simple Squamous
What is the function of fibroblasts?
Repair, formation of collagen and formation of the ground substance
- Main thing: secrete collagen
