Connective Tissue Flashcards
Does epithelial sit on top of connective tissue
True or false
True
What are the four main types of connective tissue
Connective tissue proper, cartilage, bone and blood
What are the functions of connective tissues
Binding, support, connects body parts, protection, insulation, storage and transportation
Where are all connective tissue developed from
They are all derived from a particular type of embryonic tissue called mesenchyme
What are connective tissues made up of
Cells + extracellular matrix (ground substance) + water
What makes up the extracellular matrix
Ground substances and fibers
What is ground substance
It’s the material that fills the space between the cells and connects all the fibers and enable transportation of metabolites
What is ground substance made up of
Proteoglycans, cell adhesion proteins and fluid (act as a glue)
And within the ground substance are fibers
What are the fibers of the connective tissue
. Collagen fibers (strongest)
. Elastic fibers (long, thin, stretchy, form networks)
. Reticular fibers
Can cells be immature and mature
True or false
True
What are the two types of connective tissue proper
Loose connective tissue and dense connective tissue
What are three types of cartilage
- Hyaline cartilage (it is shapeless but firm)
- Elastic cartilage (has elastic fibers in matrix)
- Fibrocartilage (found in discs)
What is bone made up of
Collagen and calcium salts (what makes bone hard), unlike cartilage bone does contain blood vessels
Why is blood a connective tissue
Because it develops from mesenchyme
What is blood made up of
Consist of watery fluid called plasma
What bone connective tissue type makes up the articular disc in the TMJ
Fibrocartilage
What is the other type of connective tissue proper
Loose connective tissue
