Classification of Joints

Definition
Based on the mobility of the joint
Term

Structural

 

Classification of Joints

Definition

Based on types of tissues that unite or bind the articulating bones

 

3 Distinct Groups:

 

Fibrous

Cartilaginous

Synovial

Term

Syndesmosis


(Structural)

Definition

Immovable joint or very slightly moveable joint joined by fibrous tissue

 

Example: Tibiofibular Joint

 

(Fibrous)

Term

Suture

 

(Structural)

Definition

Immovable joint only found in the skull, bound tightly by connective tissue

 

(Fibrous)

Term

Gomphosis

 

(Structural)

Definition

Immovable joint found only in the roots of the teeth

 

(Fibrous)

Term

Symphysis

 

(Structural)

Definition

Slightly moveable, bones are separated by a pad of fibrocartilage.  These joints are designed for strength and as shock absorbers

 

Example: Pubic symphysis and between each vertebral body

 

(Cartilaginous)

Term

Synchondrosis

 

(Structural)

Definition

Immovable joint. Contains a rigid cartilage that unites two bones.

 

Example: Epiphyseal Plate (temporary joint)

 

(Cartilaginous)

Term

Gliding

 

(Structural)

Definition

Freely moveable.  Permits only uni-directional movement.

 

Example: Intercarpal and intertarsal bones of the wrist and foot

 

(Synovial)

Term

Hinge

 

(Structural)

Definition

Freely moveable.  Permits flexion and extension.

 

Permits only uni-directional movement

 

Example: Elbow, Knee, Ankle

 

(Synovial)

Term

Pivot

 

(Structural)

Definition

Freely Moveable.  Rotation on a single axis

 

Permits only uni-directional movement

 

Example: C1-C2

 

(Synovial)

Term

Ellipsoid

 

(Structural)

Definition

Freely Moveable.  Permits flexion & extension, abduction & adduction.

 

Provides movement in two directions.

 

Example: Radiocarpal joint of the wrist

 

(Synovial)

Term

Saddle

 

(Structural)

Definition

Freely Moveable. Permits side to side, up & down.

 

Provides movement in 2 directions

 

Carpometacarpal joint between the trapezium and first metacarpal is the only saddle joint in the body

 

(Synovial)

Term

Ball and Socket

 

(Structural)

Definition

Freely Moveable.  Permits flexion & extension, abduction and adduction, circumduction and rotation

 

Where a round head of a bone sits in a cup shape portion of another bone

 

Example: Hip

 

(Synovial)

Term
Arthrology
Definition
the study of joints, or articulations between the bones
Term

Joints aid bones in the support of the body by

 

Definition

--Supporting the body

 

--Protecting the internal organs

 

--Creating movement
