Classification There are two major types of articulations or joint. ◼ Continuous joints ◼ Fibrous joints : bones are united by fibrous connective tissue ◼ Cartilaginous joints : bones are united by cartilage ◼ Synosteosis ◼ Discontinuous joints － synovial joints
S synovial joints Basic structures Articular surface: covered by y articular cartilage ■ Articular capsule Fibrous membrane Synovial membrane Articular cavity: containing a trace of synovial fluid; subatmospheric pressure in it
Synovial joints Basic structures ◼ Articular surface: covered by articular cartilage ◼ Articular capsule ◼ Fibrous membrane ◼ Synovial membrane ◼ Articular cavity: containing a trace of synovial fluid; subatmospheric pressure in it
Accessory structures Ligaments (lig. ):extra- and intracapsular ligaments Articular disc and articular labrum a Synovial fold and synovial bursa se es
Accessory structures ◼ Ligaments(lig.): extraand intracapsular ligaments ◼ Articular disc and articular labrum ◼ Synovial fold and synovial bursa
Movements of joints Translation Flexion and extension Adduction and abduction ■ Rotation Medial and lateral rotation ■ Pronation ans supination Inversion and eversion ■ Circumduction
