Chapter 8 Highlights Flashcards
1
Q
Joint classification by motion
A
Synarthrosis
Amphiarthrosis
Diarthrosis
2
Q
Synarthrosis
A
No movement
3
Q
Amphiarthrosis
A
Small amount of movement
4
Q
Diarthrosis
A
Freely moveable
5
Q
Joint classification by structure
A
Fibrous
Cartilaginous joints
Synovial joints
6
Q
Fibrous
A
- Fastened by dense regular collagenous connective tissue
- No space between articulating bones
- Synarthrosis or amphiarthrosis
7
Q
Cartilaginous joints
A
- Fastened together with cartilage
- No joint space
- Synarthrosis or amphiarthrosis
8
Q
Synovial joints
A
- Layer of hyaline cartilage on articulating bones
- Joint space has a fluid-filled cavity b/t articulating bones
9
Q
Types of synovial joints
A
- Plane
- Hinge
- Pivot
- Condylar/ellipsoid
- Saddle
- Ball-and-socket
10
Q
Plane
A
Most simple and least mobile articulation between flat surface of two bones
11
Q
Hinge
A
- Convex articular surface of one bone interacts with concave depression of second bone
- Allows for uniaxial movement
12
Q
Pivot
A
- Rounded end surface of one bone fits into groove on surface of second bone
- Uniaxial movement, one bone pivots or rotates around other
13
Q
Condylar/ellipsoid
A
- Convex surface of one bone fits into shallow concave articular surface of second bone
- Biaxial joint
14
Q
Saddle
A
- Each bone’s articulating surface has both concave and convex region
- Biaxial
15
Q
Ball-and-socket
A
- Articulating surface of one bone is spherical
- Fits into cup-shaped depression in second bone
- Multiaxial articulation
