Joints Flashcards
1
Q
articulation
A
where 2 bones join together
2
Q
types of movement
A
freely moveable
limited
or no movement
3
Q
what does joint structure do
A
- determines direction and distance of movement
- ROM (range of motion)
4
Q
what’s a synovial joint
A
- freely moveable
- contains synovial fluid
- movements limited by (muscle, ligament, joint capsule, shape)
5
Q
articular cartilage
A
- hyaline
- provides smooth surface
6
Q
joint cavity
A
- synovial
- encloses articular surfaces
7
Q
synovial fluid
A
- complex mixture of polysaccharides, proteins, fat and cells
8
Q
fibrous capsule
A
- dense irregular connective tissue, continuous with fibrous layer of the periosteum
- portions may thicken to form ligaments
9
Q
synovial membrane and fluid
A
- membrane lines inside of joint capsule
- thin, delicate
- hyaluronic acid - slippery
- no blood vessels or nerves in articular cartilage (nutrients from nearby blood vessels and synovial fluid)
- nerves in capsule help brain know position of joints (propreaception)
