Synovial Joint Injuries
Miscellaneous
100
Thin membrane covering the joint that has high blood flow and nerve conduction
What is the synovial membrane
100
Joint type that provides motion in flexion and extension only
What is hinge
100
Signs and Symptoms associated with a grade I sprain
What is mild pain, minimal loss of function, no abnormal motion, mild point tenderness, limited decrease in stability
100
Signs and symptoms of a Grade III sprain
What is extreme pain, loss of function, severe instability and swelling, may also cause subluxation
100
An accumulation of swelling inside a joint that occurs after an injury inside the joint capsule, such as a ligament sprain
What is joint effusion
200
semi-firm connective tissue on the ends of our bones
What is Articular Cartilage
200
Joint that allows for motion in all planes
What is ball and socket
200
This is an acute injury causing a complete tear of ligaments or joint capsule structures
What is a Grade III sprain
200
Dislocations decrease this type of stability
What is structural and possibly functional
200
These joints are most likely to be sprained
What are fingers, knee and ankle
300
Sheets or bundles of collagen that connect bone to bone
What are Ligaments
300
This type of joint provides for motion in flexion, extension, abduction and adduction and is in the proximal joint in our fingers
What is ellipsoidal
300
This injury can be chronic or acute
What is bursitis
300
As per the reading we did, increasing muscle tone and therefore the functional stability, will decrease the chance of injury to the structural stability and overall decrease in chance of injury
THIS WILL BE ON THE QUIZ!!! The question will read: According to the reading we did in class, how does increasing muscle tone decrease the chance of structural injury?
300
If you increase the amount of bone-to-bone articulation, this does what to structural stability?
Increases structural stability
400
A fibrous cuff connecting bones across the joint that help to maintain relative joint position
What is the joint capsule
400
There is only one of these in our bodies (at our thumb) and has motion in 4 directions
What is Saddle
400
Signs and symptoms associated with dislocation
What is loss of limb function, gross deformity, and swelling/point tenderness
400
These should always be considered a fracture and referred to a physician
What is a dislocation
400
These joints have the most structural stability because of the high amount of bone-to-bone surface area touching (articulation)
What is gliding
500
Functions of synovial fluid
What are: lubrication, shock absorption and nutrition to the joint
500
The type of motion that pivot joints allow
What is rotation
500
Incomplete separation of two bones in a joint
What is a subluxation
500
Major cause of this injury is failure of muscle to control or limit deceleration in a joint, causing irritation or compression
What is bursitis
500
These joints require the most functional stabilization due to their minimal structural stabilization and bony articulation
What is ball & socket
