38
Q

What are the components of a synovial joint?

A
  1. Gap between at least 2 bones
  2. Joint capsule
  3. Synovial fluid
  4. Hyaline cartilage on opposing surfaces
39
Q

What are the layers of a synovial joint?

A
  1. Stratum fibrosum
  2. Stratum synoviale
40
Q

Stratum fibrosum

A
  • Fibrous avascular tissue layer
  • Transverse fibres, sometimes thickening into ligaments
  • Ligaments: Capsular, intracapsular or extracapsular
  • Collateral ligaments - Outside joints (Support)
41
Q

Stratum synoviale

A
  • Capillary supply
  • Internal wall of capsula articularis
  • Internal wall covered by villi synoviales (Produce synovium)
  • Synovium fills the cavitas articularis
42
