Articular Cartilage

Hyaline cartilage covers the opposing bone surfaces and the main function is to absorb compression.


Purse" are flattened fibrous sacs lined with synovial membrane and containing a thin film of synovial fluid, occuring where bones rub together.


The most abundant joint type in the body, opposing bones separated by fluid filled cavity. Classified as Diathrotic (Free movements)


Amphiarthrotic -Slightly movable articular surfaces seperated by thin layers of hyaline cartilage that is attached to a pad of fibrocartilage. vertebral joints


Synarthrotic(immovable) bones united by bands of hyaline cartilage. joint between epiphysis & diaphysis

Cartilaginous Joints

Articulating bones connected by hyaline cartilage or fibrocartilage.


Cone shaped process fastened in bony socket by peridontal ligament Synarthrotic (immovable)


Freely movable (synovial) joints.
hinge plane saddle ball & socket pivot condylar
elbow carpal trapezium hip vertebrae phalanx


Literally "seams," only occur between bones of the skull. Synarthrotic

Joints (articulations)

The sites where two or more bones meet.


Slightly movable joints


Are immovable joints

condylar (condor)
phalanx metacarpal

plane joint

hinge joint
humerus radius ulna

saddle joint
1st metacarpal trapezium

ball & socket joint
femur/ head of femur/ hip

pivot joint
Dens / transverse ligament / axis / atlas


This is a slightly movable (Ampiarthrotic) articulation where the contiguous bony surfaces are united by an interosseous ligament, as in the inferior tibiofibular articulation.

synovial (diarthrotic)

articulating ends of bones surrounded by a joint capsule
articular bone ends covered by hyaline cartilage and seperated by synovial fluid


Condylar joints do not rotate


joints between various bones of the wrist and ankle


Cylindrical surface articulates with ring of bone and ligament


articulating surfaces have "both" concave and convex regions / surface of one bone fits the complimentary surface of another in "two planes". trapezium

ball & socket

allows for movements in all planes includes rotation


a concave surface of one bone fits into the convex surface of another allows flexation and extension
