Lecture 9 Flashcards
1
Q
Fibrous Joints
A
Tissue = DFCT
Structure = Ligament
Function = Limited movements/stability
Example = Cranial suture
Distal tibia fibula joint
2
Q
Cartilaginous Joints
A
Tissue = Fibrocartilage
Special functions and various strictures
Some movement
Example = intervertebral disc (structure)
pubic symphysis
3
Q
Synovial Joints
A
- Free moving
- Most limb joints
- Complex association of tissues and structures
- Facilitation of free movement and control of movement
- Bones ends determine the range of motion at a joint
- Articular cartilage
- Covers bone ends where they articulate and move over each other
- Subchondral bone is smooth
4
Q
What are capsular ligaments?
A
- Hold bones together
- Tight and thick where more support is required - loose on sides where movement is allowed
- Potential space/cavity
5
Q
The synovial membrane lines the:
It also secretes:
This leads to:
A
Inner surface of the capsule.
Synovial fluid
Lubrication of the joint.
6
Q
Collateral ligaments of knee:
medial restricts……
lateral restricts……
A
abduction
adduction
7
Q
Outline the intracapsular ligament:
A
- Restricts moment between bones
- Cruciate ligaments
- Arise from tibia and insert into femur
- Anterior cruciate restricts posterior displacement of femur.
