Joints (dave's notes) Flashcards
Give three types of joints
Fibrous
Cartilagenous
Synovial
What are fibrous joints? Give an example
Joints between bones and cartilage. There is negligible movement and they gradually ossify (skull)
What types of cartilaginous joints exist?
Primary and secondary
What are primary cartilaginous joints?
Joints between bone and hyaline cartilage
Give two examples of primary cartilaginous joints
Epiphyses and rib junctions
What are secondary cartilaginous joints?
Secondary (symphysis) fibrous union between two bones covered by hyaline cartilage
Give two examples of secondary cartilaginous joints
Pubic symphysis
Manubriosternal angle
Give six characteristics of synovial joints
- Bone ends covered in hyaline cartilage
- Surrounded by a capsule
- Joint cavity
- Reinforcing ligaments
- Lined by internal synovial membrane
- Varying degrees of movement
What property does synovial fluid have?
The ability to modify its viscosity becoming thinner with rapid movement
Where do discs and menisci develop? Where do they characteristically occur?
Discs and menisci develop in membrane, occurring characteristically where two separate movements take place
Where do blood vessels grow from in developing bone?
The centre of ossification
What is the site where the end of the shaft is in contact with the epiphysis?
The metaphysis
What type of arteries supply metaphases?
End arteries
When are vascular communications made?
Not until there is cessation of growth
Why is joint pain poorly localised?
Synovial membrane has very few pain fibres
