Q

Describe the differences between a synovial + a solid joint

A

In a synovial joint, the elements are separated by a cavity, whereas in solid joints there is no cavity, but the elements are held together by connective tissue (fibrocartilage)

Q

Describe the characteristics of a synovial joint

A
  1. The elements are separated by an articular disc
  2. Hyaline cartilage covers the articular surfaces
  3. They have a joint capsule
    with an inner synovial membrane (excretes synovial fluid) + an outer fibrous membrane
