Q

Fibrous joints

A

2 bones are united by fibrous CT
Exhibit very little to no movement at all

Three classifications:
Sutures
Syndesmoses
Gamphoses

1
Q

Classes of joints

A

Fibrous
Cartilaginous
Synovial

2
Q

Sutures

A

Seams between skull bones
Very stable
Opposing bones have interlocking processes

Ex: coronal suture between frontal and parietal bone

3
Q

Syndesmoses

A

Joins bones to a ligament
Flexible, so some movement can occur

Ex: tibiofibular joint

4
Q

Gamphoses

A

Specialized joints consisting of pegs and sockets
Held together by CT tissue called periodontal ligaments

Ex: between teeth and mandible and maxilla

5
Q

Cartilaginous joints

A

Two bones united together by hyaline cartilage or fibro cartilage

Two classifications:
synchondroses
Symphyses

6
Q

Synchondroses

A

2 bone suited by hyaline cartilage
Little to no movement

Ex: epiphyseal plate
Between the costal cartilage of the 1st rib and the manubrium

7
Q

Symphyses

A

2 bones joined by fibrocartilage
Flexible, some movement can occur

Ex: pubic symphyses
Intervertebral disc

8
Q

Synovial joints

A

Articulating bones that are separated by a fluid filled joint cavity

Fluid is called synovial fluid
Includes most joints of the body (ALL joints of articulating limbs)
Highly moveable
