Classification of articulations

Classification of Articulations
By Sadie Gordon & Bob

Classification of joints
Functionally
Fibrous
Dense Regular Connective Tissue
Cartilaginous
Cartilage
Synovial
Fluid Filled Joint Cavity
Structurally
Synarthrosis
Immobile
Amphiarthrosis
Slightly Movable Joint
Diarthrosis
Freely Mobile Joint

Functional Classification
Synarthrosis
An Immobile Joint
Amphiarthrosis
Slightly Mobile Joint
Diarthrosis
Freely Mobile Joint

Structural Classification
Fibrous
Dense irregular connective tissue that holds bone to bones
No joint cavity
Cartilaginous
Pad of cartilage wedged between bones
No Joint cavity
Synovial
Ends of bones are covered with cartilage
Joint capsule is lined with synovial fluid
All synovial joints are freely moveable (diarthrotic)

Fibrous Joints
Gomphosis
Suture
Syndesmosis

Gomphosis
Membranes that holds tooth in the Jaw
Example tooth in the Jaw
Functionally classified as Synarthrosis (immobile)

Suture
Dense regular connective tissue that connects skull bones
Example: Lambdoid Suture
Functionally Classified as Synarthrosis

Syndesmosis
Dense regular connective tissue fibers between bones
Examples: Syndesmosesare the articulations between the fibula and the fibula, and the radius and the ulna
Functionally classified
as Amphiarthroses(slightly moveable)

Types of Cartilaginous Joints
Synchondrosis
Symphysis

Synchondrosis
Hyaline cartilage plate between bones
Examples: Epiphyseal plates, and Costochondral joints
Functional Classified as Synarthrosis

Examples of Synchondrosis Joints

Symphysis
Fibrocartilage pad between bones
Examples: Pubic symphysis, and intervertebral disc
Functional classified
as Amphiarthrosis

Synovial
Uniaxial
Plane joint
Hinge Joint
Pivot joint
Biaxial
Condylar joint
Saddle joint
Multiaxial
Ball-and-socket joint

Uniaxial
Plane joint
Flattened or slightly curved faces slide across on another
Example: Intercarpal joints & Intertarsal joints
Functionally Classified as Diarthrosis
Hinge Joint
Permits angular movements in a single plane
Example: Elbow Joint
Pivot joint
Permits rotation only
Example: Atlantoaxial joint

Biaxial
Condylar joint
Oval articular surface on one bone closely interfaces with a depressed oval surface on another bone
Examples: MP joints
Saddle joint
Saddle-shaped articular surface on one bone closely interfaces with depressed surface on another bone
Example: Articulation between carpal and first metacarpal bone

Multiaxial
Ball-and-socket joint
Round head of one bone rests within cup-shaped depression in another bone
Example: Glenohumeral joint, and hip joint
