INTRO TO ARTHOLOGY Flashcards
One axis of joint movement
Uniaxial
Two axes of joint movement
Biaxial
Multiple axes of joint movement
Multiaxial
Joint connected by fibrous tissue. Movement depends on amount of fibrous tissue between the articulation surfaces
Fibrous joint
Fibrous joint that has limited movement occurring only in skull
Sutures Joint
Sheet of fibrous tissue connecting bones providing movements
Syndesmosis Joint
Joint connected by cartilage or a combo of cartilage and fibrous tissue
Cartilaginous Joint
A combination of cartilage and fibrous tissue
Fibrocartilagenous
Cartilaginous joint connecting the vertebrae
Fibrocartilagenous intervertebral discs
Space between the 2 joint surfaces
Joint Cavity
A whitish connective tissue that covers the ends of bones
Articular Cartilage
Surrounds/lines joints. Prouces synovial fluid within joint
Joint Capsule
A biaxial joint type performing flexion/extension and abduction/adduction (and circumduction)
Condyloid Joint (Ellipsoid joint)
A biaxial joint with opposing surfaces are shaped like saddles (concave and convex articulation)
Saddle joint
A multiaxial joint with a ball-shaped surface articulating with a socket of other surface
Ball and Socket joint
A uniaxial joint with a flat joint surface providing gliding/sliding movements
Plane joint
A uniaxial joint with a rounded process rotating within a ring
Pivot joint
A uniaxial joint performing flexion and extension movements only
Hinge joint (Ginglymics joint)
Synovial fluid sacs that decrease friction generated by motion
Bursa
Joint position that is increased stability and decreased mobility. Ligaments and joint capsule are tight.
Closed-packed position
Joint position that is increased in mobility and decreased stability. Ligaments and joint capsule are loose
Loose-packed position
