1
Q
define articulations
A
location where bones come together
2
Q
define synarthroses
A
immobile (or almost) joints
3
Q
define amphiathroses
A
limited mobility
4
Q
define diarthroses
A
- freely mobile
- all synovial joints
5
Q
what are the sections of structural characteristics of joints?
A
- fibrous joints
- cartilaginous joints
- synovial joints
6
Q
Define Fibrous joints
A
- bones directly connected to each other by fibrous connective tissue
- no joint cavity
- gaps are narrow or wide
7
Q
Types of Fibrous joints
A
- sutures
- syndesmosis
- gomphosis
8
Q
Sutures
A
- narrow fibrous joint
- found btwn bones of skull
- synarthroses (immobile): except for in babies
9
Q
Syndesmosis
A
- widely separated fibrous joints
- held together by ligament or interosseous membrane
- amphiarthroses: limited movement to provide strength and stability
- ex. ankle
10
Q
Gomphosis
A
- synarthroses: immobile
- connects tooth to jaw
- numerous periodontal ligaments: anchors root of tooth into bony socket
11
Q
Define Cartilaginous joints
A
- bones joined by cartilage (hyaline or fibrocartilage)
- no joint cavity
12
Q
types of cartilaginous joints
A
- synchondrosis
- symphysis
13
Q
Synchondrosis
A
- cartilaginous joint joined by hyaline cartilage
- synarthroses: immobile
- can be temporary or permanent
14
Q
Symphysis
A
- cartilaginous joint joined by fibrocartilage
- amphiarthrosis: limited mobility
- gap separating bone is narrow or wide
15
Q
Define synovial joints
A
- most common joint
- has a joint cavity
- articulating surfaces not directly connected to con. tissue or cartilage
- diarthroses
- bones connected by ligaments
16
Q
Role of joint cavity
A
- fluid filled space
- site where articulating surfaces of bones contact each other
