Articulation =
a joint

Arthrosis: An arthrosis is a joint
An articulation or joint or arthrosis is a point of contact between:
- neighbouring bones
- bone and cartilage
- bone and teeth

Fibrous Joints
- No … cavity
- Held together by a fibrous … tissue
- Permits little or no movement (synarthrosis/amphiarthrosis)
- Three types of fibrous joint:
- 1) Suture
- 2) Syndesmosis
- 3) Interosseous membrane
- No synovial cavity
- Held together by a fibrous connective tissue
- Permits little or no movement (synarthrosis/amphiarthrosis)
- Three types of fibrous joint:
- 1) Suture
- 2) Syndesmosis
- 3) Interosseous membrane

What movement do fibrous joints permit?
little or no movement - synarthrosis/amphiarthrosis
What are the three types of fibrous joints?
Suture, Syndesmosis, Interosseous membrane
Fibrous joints - Suture
- Unite … bones
- Thin layer of dense connective tissue
- Irregular
- Interlocking edges provide strength, permit no movement (Synarthrosis)
- Ossification of a suture forms a synostosis
- e.g left and right sides of frontal bones fuse - 6yrs of age
- Unite skull bones
- Thin layer of dense connective tissue
- Irregular
- Interlocking edges provide strength, permit no movement (Synarthrosis)
