Document Summary
Explain the major characteristics of a synovial joint. Articulations/ joints: place where 2 or more bones or cartilage make contact/connect. Joint classification: solid, fibrous, suture, syndesmosis, gomphosis, cartilaginous, sunchrondosis, symphysis, synovial, nonaxial (plane) no axis movement (glides, monoaxial (hinge, pivot, biaxial (condyloid, saddle, multiaxial (ball and socket) Syndesmosis: more movement due to space between bones held together by tissue i. e. interosseous membrane hold syndesmosis together. Gomphosis joint: between teeth and jaw peg and socket. Connected by cartilage rather than fibrous or no tissue. Can be connected by hyaline or fibril cartilage. Hyaline cartilage: allows bones to grow at epiphyseal growth plate and gone by adulthood. Symphysis joint is joined by fibrocartilaginous discs and in midline. All symphysis joints found in midline and all joints in midline are symphysis i. e. pubic symphysis joins the halves together found in midline. Separated by fluid-filled joint cavity synovial fluid. All are freely moveable vary in degree of mobility.
