Joints II- Joint classifications Flashcards
Name the movements and axial amount of the plane joint
- multiaxial
- sliding + gliding
What is the joint capsule?
Sheet of dense fibrous connective tissue that is continuous with periosteum and holds bones together.
Properties of Synovial Joints:
- free- moving
- mostly limb joints
- amount and direction of movement is. determined by joint structure (bone. ends)
What is an example of a hinge joint?
- ankle
- elbow
Name the movements and axial number of a pivot joint:
- uniaxial
- rotation
What is an example of a plane joint?
- inter-carpal
- inter-tarsal
What is the name for the Sheet of dense fibrous connective tissue that is continuous with periosteum and holds bones together?
joint capsule
What is the name for the Membrane that lines the inner surface of the joint cavity and secretes synovial fluid?
Synovial membrane
What is an example of a ball and socket joint?
- hip
- shoulder
What is the synovial membrane?
Membrane that lines the inner surface of the joint cavity and secretes synovial fluid
Name the movements and the axial number of a Hinge joint:
- uniaxial
- flexion and extension
What joint classification is:
- biaxial
- movements are flexion and extension
- abduction and adduction
- circumduction
Ellipsoid
What joint classification is:
- biaxial
- movements are flexion + extension
- rotation (when flexed)
Condylar
What classification of joint is:
- multiaxial
- movements are sliding + gliding
Plane joint
What is a capsular ligament?
Thickened region of the joint capsule where more support is needed
Name the movements and axial number of the Ball and socket joint:
- Multiaxial
- flexion and extension
- abduction and adduction
- circumduction
- rotation
What are the (6) important parts of a synovial joint?
- bone ends
- articular cartilage
- joint capsule
- joint cavity
- synovial membrane
- ligaments
What is an example of a saddle joint?
carpometacarpal joint (Thumb)
What is the name for a Thickened region of the joint capsule where more support is needed
Capsular ligament
Name the movements and the axial number of the Ellipsoid Joint:
- biaxial
- flexion and extension
- abduction and adduction
- circumduction
What joint classification is:
- uniaxial
- movements are flexion and extension
Hinge
What joint classification is:
- Multiaxial
- movements are flexion and extension
- abduction and adduction
- circumduction
- rotation
Ball and socket
Name an example of a pivot joint:
- radioulnar joints
- C1-C2 vertebrae
Name the movements and axial number of a Condylar joint:
- biaxial
- flexion + extension
- rotation (when flexed)
What type of joint is:
- uniaxial
- movement is rotation
Pivot
Name the 7 classifications of synovial joints:
- plane
- hinge
- saddle
- ball and socket
- pivot
- condylar
- ellipsoid
What is an intracapsular ligament?
ligaments separate from but inside joint capsule
Name an example of a condylar joint:
Knee
What joint classification is:
- biaxial (+)
- movements are Flexion and extension
- adduction and abduction
- circumduction
- opposition
Saddle
Name the movements and the axial number of the Saddle joint:
- biaxial (+)
- Flexion and extension
- adduction and abduction
- circumduction
- opposition
What is the function of synovial fluid?
- lubrication of joint
- nutrients to articular cartilage via joint loading
