9/7/2023 0 Comments Functions of synovial fluidAt synovial joints, the articular surfaces of bones are covered with smooth articular cartilage. This fluid-filled space is the site at which the articulating surfaces of the bones contact each other. A key structural characteristic for a synovial joint that is not seen at fibrous or cartilaginous joints is the presence of a joint cavity. Synovial joints are the most common type of joint in the body ( Figure 9.4.1). Name an example of each of the six types of synovial joints and describe its functional properties.Compare the six types of synovial joints.Discuss the function of additional structures associated with synovial joints.Describe the structural features and functional properties of a synovial joint.Experimental intrinsic healing of flexor tendons based upon synovial fluid nutrition.By the end of this section, you will be able to:ĭescribe the characteristic features for synovial joints and give examples.Experimental studies on cellular mechanisms involved in healing of animal and human flexor tendon in synovial environment.Role of synovial fluid cells in the healing of flexor tendons.The synovial cavity as a "tissue culture in situ"-science or nonsense?.The healing of freeze-dried rabbit flexor tendon in a synovial fluid environment.Brucellar arthritis of the knee: a case report with delayed diagnosis.The value of synovial fluid assays in the diagnosis of joint disease: a literature survey.Synovial pH in rheumatoid knee-joints.The effect of local corticosteroid treatment.
