A joint that has little or no movement.
EX:sutures, teeth(gomphosis)
Synarthrotic Joint
A joint that has slight movement.
EX: distal Tibia-Fibula(syndesmosis), Pelvic Girdle
Amphiarthrotic Joint
A joint that has free movment. EX: ball & socket, hinge, gliding, saddle, pivot, and ellipsoid joints
Diarthrotic (Synovial) Joint
Movement: between clavicle and sternum
Gliding
Movement:away from the body's longitudinal axis
Abduction
Movement:toward body's longitudinal axis
Adduction
Movement:increase in angle between elements
Extension
Movement:decrease in angle between elements
Flexion
Movement:gross orbital movement of element
Circumduction
Movement:rolling movement along axis
Rotation
Movement:rotation of palm/sole to face anteriorly
Supination
Movement:rotation of palm/sole to face posteriorly
Pronation
Movement: "extension anteriorly (horizontal)
Protraction
Movement: "flexion" posteriorly (horizontal)
Retraction
A degenerative joint disease: weight bearing joints suffer cartilage erosion.
Osteoarthritis
A bacterial insult(synovitis): a degeneration of cartilage from typically monoarticular/ large joints. There is also injury an reduced immuno-competance.
Suppurative arthritis
A chronic inflammatory disease that results from a systemic erosion of synovium w/ vascularized mass. It is typicaly in the wrist and hands small bones.
Rheumatoid arthritis
A metabolic disorder(hyperurecemia): This is where body fluids are saturated with monosodium urate and crystals for in joints.
Gouty Arthritis
Fusion of adjacent bones due to friction/trauma.
Ankylosis
The largest muscle at joint movement.
Agonist
Muscle that reverses movement.
Antagonist
Muscle that adds to movement/stabilization of the joint.
