Synchrondoses = synarthrotic, cartilagenous joints

Syndesmoses = synarthrotic, fibrouss joints

Symphyses = ampiarthrotic, cartilangenous joints

Front 19

Describe the structure of a synovial joint

Back 19

the bones are covered in peritosteum CT except for the eiphysis which have articular (hyaline) cartilage

the articular cartilage is bordered by the synovial membrane to form the synovial cavity.

outside of the synovial membrane is the fibrous capsule.

outside the fibrous capsule are ligaments
