Articular Cartilage
Hyaline cartilage covers the opposing bone surfaces and the main function is to absorb compression.
Bursae
Purse" are flattened fibrous sacs lined with synovial membrane and containing a thin film of synovial fluid, occuring where bones rub together.
Synovial
The most abundant joint type in the body, opposing bones separated by fluid filled cavity. Classified as Diathrotic (Free movements)
Symphysis
Amphiarthrotic -Slightly movable articular surfaces seperated by thin layers of hyaline cartilage that is attached to a pad of fibrocartilage. vertebral joints
Synchondrosis
Synarthrotic(immovable) bones united by bands of hyaline cartilage. joint between epiphysis & diaphysis
Cartilaginous Joints
Articulating bones connected by hyaline cartilage or fibrocartilage.
Gomphosis
Cone shaped process fastened in bony socket by peridontal ligament Synarthrotic (immovable)
Diarthroses
Freely movable (synovial) joints.
hinge plane saddle ball & socket pivot condylar
elbow carpal trapezium hip vertebrae phalanx
Sutures
Literally "seams," only occur between bones of the skull. Synarthrotic
Joints (articulations)
The sites where two or more bones meet.
Ampiarthroses
Slightly movable joints
Synarthroses
Are immovable joints
condylar (condor)
phalanx metacarpal
plane joint
carpals
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
Syndesmosis
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
Condylar joints do not rotate
plane
joints between various bones of the wrist and ankle
pivot
Cylindrical surface articulates with ring of bone and ligament
saddle
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
hinge
a concave surface of one bone fits into the convex surface of another allows flexation and extension
