Joints Flashcards
What are the 3 types of joints
Fibrous
Cartilaginous
Synovial
What are the two types of fibrous joints
Synarthroses - sutures are immobile (skull plate)
Syndesmoses- slightly moveable and connected by ligaments
What are the 2 types of cartilaginous joints
Synchondroses - contains hyaline cartilage
Symphyses- contains fibrocartilage
What is inside a synovial joint
Contains a spaced filled with synovial fluid
What are the 6 synovial joints
Hinge
Ball and socket
Condyloid
Pivot
Plane
Saddle
What is the difference between a synarthrosis, amphiarthrosis and diarthrosis joint
Synarthrosis
- don’t move at all
Amphiarthrosis
- slight movement
Diarthrosis
- freely moveable
Where is synovial fluid produced
In the synovial membrane
How is synovial fluid moved within a Diarthrodial joint
Through compression of the joint capsule when the joint is loaded during cyclic loading
How is nutrients moved in and out of a joint
Through compression and decompression if the joint during cyclic loading
How is OA triggered without trauma
Instability of the joint and uneven loading which could be due to confirmation
What are the 4 structures of a joint which need to be damaged to create lameness
Joint capsule
Subchondral bone
Ligaments synovial membrane
What are ligaments made from
A tough fibrous band of dear regular connective tissue that connects bone to bone
Function of ligament in relation to joints
Strengthen joints and prevents joints from twisting but allow slight movement for shock absorption
How do ligaments heal
Ligaments heal through scaring which alters the biomechanics and overall stand length of the ligaments
