Three classes of joints based on structure
Fibrous - no joint cavity, held together w fibrous CT
Cartilaginous - no joint cavity, joint held together w cartilage
Synovial - has a joint cavity, bones held together by ligaments
Define articulation
A point of contact between bones, cartilage, and bone or teeths of bone
Synarthrosis
Immovable
Amphiarthrosis
Slightly moveable
Diarthrosis
Freely moveable
Slightly moveable joint
Amphiarthrotic
Sutures between skull bones are examples of
Synarthrotic
Freely moveable joint
Diarthrotic
Discs between vertebrae are examples of
Amphiarthrotic
Attachment of a tooth to its socket in the mandible or maxilla
Synarthrotic
Immovable joint
Synarthrotic
More mobile than a suture but less mobile than a joint like the elbow
Amphiarthrotic
The symphysis pubis is an example of
Amphiarthrotic
The distal end of the tibia/fibula is an example of
Amphiarthrotic
The epiphysial plate in a growing bone is an example of
Synarthrotic
Hyaline cartilage that covers ends of articulating bones
Articular cartilage
It lubricates the joints and nourishes the cartilage
Synovial fluid
Inner layer of the articular capsule that produces synovial fluid
Synovial membrane
Pad of cartilage to help stabilize the joint
Meniscus
Together these form the articular capsule
Fibrous capsule and synovial membrane
Fluid filled sac that cushions movements
Bursa
The joint allowing for the greatest degree of movement
Ball and socket
The surfaces of carpals or tarsals move across each other
Gliding
The joint at the wrist between the radius and carpals
Condyloid
