General Classification by Function (i.e. degree of movement permitted)
*Classification by joint structure is shown in parentheses.

1. SYNARTHROSIS: no movement allowed

a. Suture- (fibrous joint)

examples: sagittal suture, coronal suture, etc.

b. Synchondrosis- (cartilaginous joint)

examples: metaphysis of growing bone; 1st rib with the sternum

c. Gomphosis- (fibrous joint) example: teeth in sockets

2. AMPHIARTHROSIS: slight movement allowed at the joint

a. Symphysis- (cartilaginous joint) examples: between vertebral bodies (intervertebral disc); symphysis pubis; sacroiliac joint

b. Syndesmosis- (fibrous joint) example: between tibia and fibula; interosseous ligament between radius and ulna

3. DIARTHROSIS: all of the diarthroses are freely moveable synovial joints

a. Ball and Socket- examples: hip and shoulder joints

b. Ellipsoidal (Condyloid)- examples: joints between the 2nd-5th metacarpals and the 2nd-5th proximal phalanges; also, the joint between the distal end of the radius and ulna with the carpals

c. Gliding- examples: intercarpal and intertarsal joints; between the superior and inferior articular processes of the vertebrae; the articulations of the vertebrosternal ribs with the vertebrae and sternum; the acromioclavicular (A-C) joint

d. Hinge- examples: elbow and knee joints; interphalangeal joints

e. Pivot- examples: head of the radius in the radial notch of the ulna; atlas-axis joint

f. Saddle- example: only found between the trapezium and the 1st metacarpal of the hand
