Class of bone based on structure
Fibrous-NO joint cavity; held together by fibrous C.T.
Define the term articulation (joint)
A point of contact (a site/place) between bones, cartilage and bones, or teeth and bones
Class of bone based on structure
Cartilaginous- NO joint cavity; held together by cartilage
Class of joint based on structure
Synovial- had a joint cavity; bones held together by ligaments
What type of movement does synathrosis permit?
Immovable
What type of movement does amphiarthrosis permit?
Slightly movable
What type of movement does diarthrosis permit?
Freely movable
Slightly movable joint
Amphiarthrotic
Sutures between skull bones are examples
Synarthrotic
Freely movable joint
Diarthrotic
Discs between vertebrae are examples
Amphiarthrotic
Attachment of a tooth toots 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
Amphiarthrotic
The distal end of the tibia/fibula is an example
Amphiarthrotic
The epiphyseal plate in growing bone is an example
Synarthrotic
Hyaline cartilage that covers ends of articulating bones
Articular cartilage
It lubricates the joints and nourishes the cartilage
Synovial fluid
Pad of cartilage to help stabilize the joint
Meniscus
Together these form the articular capsule
Fibrous capsule, synovial membrane
Fluid-filled sac that cushions movements
Bursa
The joint allowing for the greatest degree of movement
Ball-and-socket
Flat surfaces of the carpals or tarsals move across each other
Gliding
The joint at the wrist between the radius and carpals
Condyloid
Moves in a single plane at the knew or elbow
Hinge
The joint between the carpals and the metacarpal of the thumb
Saddle
The rounded head of the radius moves within the radial notch of the ulna
Pivot
Movement of a bone around its own axis
Rotation
Movement away from the midline of the body
Abduction
Palm faces upward or forward
Supination
Downward movement of a body part
Depression
Movement toward the body midline
Adduction
Movement of the mandible or shoulder backward
Retraction
Turning the palm so it faces downward or backward
Pronation
Upward movement of a body part
Elevation
Movement of a distal end of a body part in a circle
Circumduction
Beyond the plane of extension
Hyperextension
Movement of the sole of the foot inward
Inversion
Movement of the foot so the toes point downward
Plantarflexion
How are arthrits and rheumatism related?
Arthritis is a form of rheumatism
“Wear & tear” arthritis causing deterioration of the articular cartilage is
Osteoarthritis
Displacement of a bone from its joint is a
Dislocation
Overstreching a muscle is
Strain
