Joints Flashcards
Joint function
Motion
Weight
Stability
What joint type offers the most movement
Diartroses
Components that are always associated with synovial joints?
Synovial fluid Articular cartilage Joint capsule Synovial membrane Ligaments Blood vessels Sensory nerves
What structure associated with a synovial joint is filled with synovial fluid, absorb force, and protect periarticular connective tissue
Bursa
Function of peripheral labrum
Deepen concave jt and support attachments of jt capsule
Function of Intra-articular discs
Increase congruency and improve joint force dispersion
What is the difference in movement between an ellipsoid and condyloid joint?
In addition to the Flex/ext and abd/add of an ellipsoid joint, a condyloid joint can do axial rotation (IR/ER)
Types if periarticular connective tissue
Dense connective tissue
Articular cartilage
Fibrocartilage
Difference between irregular and regular connective tissue
Irregular- collagen is oriented irregularly (can resist force from multiple directions)
Regular- collagen arranged near-parallel (most effective when stretched parallel to fibers)
Where can dense connective tissue be found
Ligaments
Joint capsule
Tendon
Function of articular cartilage
Absorb force
Reduce jt friction
Dense connective tissue function
Resist tension
Fibrocartilage function
Support and mechanically stabilize jt
Dissipate force
Guide complex Arthrokinematics
Bone function
Rigid support to the body
Systems of levers for muscle
Wolff’s law
Bone is laid down in areas of high stress and absorbed in areas of low stress
