What are the two ways joints are classified? |
Structurally Functionally |
|
|
What are the two criteria in which joints are structurally classified? |
1. Presence or absence of a space between articulating bones (synovial cavity) 2. Type of connective tissue binding bones together |
|
|
Name the 3 categories of how we classify joints structurally? |
1. Fibrous joints 2. Cartilaginous joints 3. Synovial joints |
|
|
Define what a fibrous joint is... |
No synovial cavity Bones are held together by dense irregular connective tissue (rich on collagen fibers) |
|
|
Define what comprises cartilaginous joints... |
No synovial cavity Bones are held together by cartilage |
|
|
Define a synovial joint? |
Synovial cavity present Bones united by dense irregular connective tissue of an articular capsule, Bones also often united by accessory ligaments |
|
|
Functional classification relates to what key element? |
Degree of movement joint permits |
|
|
What are the 3 functional classifications of joints? |
1. Synarthrosis 2. Amphiarthrosis 3. Diarthrosis |
|
|
Define synarthrosis joint... |
Immovable joint |
|
|
Define Amphiarthrosis joint... |
Slightly moveable joint |
|
|
Define diarthrosis joint... |
Freely moveable joint which contain a synovial cavity and permit several different types of movement |
|
|
Name the 3 types of fibrous joints... |
1. Suture 2. Syndesmoses 3. Interosseous membrane |
|
|
What is the interosseous membrane comprised of? |
Substantial sheet of dense irregular connective tissue |
|
|
How much movement is permitted in a joint with an interosseous membrane? |
Slight |
|
|
Functionally what type of joint are interosseous membranes classified into? |
Amphiarthrosis |
|
|
Orthoepdically, what is the most important cartilaginous joint? |
Symphyses |
|
|
Describe a cartilaginous structured joint... |
End of articulating bones have hyaline cartilage, and moreover, there is an ARTICULAR DISK made of fibrocartilage that connects the bones |
|
|
How is a symphyses functionally classified? |
Amphiarthrosis |
|
|
Symphyses joints are usually found where in the body? |
Midline |
