Diarthrosis
Synovial Joint Structure |
|
Definition
1. Joint capsule
2. Articular cartilage at the end of each bone that acts as shock absorbers and reduce friction
3. Joint cavity (filled with synovial fluid)
-Provides lubrication (lubricin)
-Nourishment and waste removal of the chondrocytes
-Shock absorption
4. Synovial membrane
5. Sensory nerves and blood vessels |

Diarthrosis-
accessory structures
MENISCI |
|
Definition
| fibrocartilage pads that may subdivide the synovial cavity |
|
|
Term
Diarthrosis
accessory structures
FAT PADS |
|
Definition
| provide protection for the cartilage and fill spaces created when bones move and the joint cavity changes shape |
|

accessory structures
LIGAMENTS |
|
Definition
| support and strengthen the synovial joint |

TENDONS |
|
Definition
| not part of the articulation but runs through it and their presence often limits the motion of a joint |

Diarthrosis-

BURSAE |
|
Definition
| - fluid filled pockets in CT that occur where a tendon or ligament rub against another tissue; function is to reduce friction |
|
|
Term
|
Definition
-rotation
-Gliding (linear) motion - two surfaces slide past one another
-Angular motion - when the distal end moves and the
proximal end is stable
•Extension - increases the angle between articulating surfaces
•Abduction - movement away from the axis
•Adduction - movement toward the axis
•Flexion - anterior or posterior movement that decreases the angle between articulating surfaces

-Clavicles, carpals, tarsals, articular facets of the vertebrae |
|
|
Term
|
Definition
a.Permits angular movement in a single plane
b.Elbow and knee |

|
Term
|
Definition
-permit only rotation
-joint between axis and atlas |
|
|
Term
|
Definition
-Oval articular face fits into a depression allowing angular motion
in two planes
-Fingers and toes with metacarpals and metatarsals and carpals to radius and ulna |
|
|
Term
|
Definition
-Articular face resembles a saddle (concave on one axis and convex on the other)
