Gout is a form of arthritis that results from the deposition of uric acid crystals within a body joint. Because of the disconnected nature of synovial joints, the bones do not actually touch. The most commonly involved joints are the hands, feet, and cervical spine, with corresponding joints on both sides of the body usually affected, though not always to the same extent.

Synovial fluid is a vicious material that is derived by filtration from blood True True/False The articular surfaces of synovial joints play a minimal role in joint stability True True/False The major role of ligaments at synovial joints in to unite bones and prevent undesirable movement. Risk factors that may lead to osteoarthritis later in life include injury to a joint; jobs that involve physical labor; sports with running, twisting, or throwing actions; and being overweight. The compression ratio of an Otto cycle is VA/VB=8.00V_{A} / V_{B}=8.00VA/VB=8.00.

B increasing protein synthesis The membrane surrounding each muscle fiber b. articular (joint) capsule Chronic bursitis may require that fluid be drained, but additional surgery is usually not required. In which type of joint are two bones joined by cartilage? Muscles and their tendons acting across a joint can also increase their contractile strength when needed, thus providing indirect support for the joint. At a pivot joint, a rounded portion of a bone is enclosed within a ring formed partially by the articulation with another bone and partially by a ligament (see Figure 9.4.3a). d. the hip joint, The cruciate ligaments of the knee ________.
