How does muscle attach to muscle? Bones are connected exclusively by ligaments. Friction between the bones is reduced by a thin layer of articular cartilage covering the surfaces of the bones, and by a lubricating synovial fluid, which is secreted by the synovial membrane. Watch this animation to observe hip replacement surgery (total hip arthroplasty), which can be used to alleviate the pain and loss of joint mobility associated with osteoarthritis of the hip joint. Joint movement then results in pain and inflammation. Some synovial joints also have a fat pad, which can serve as a cushion between the bones.

Rheumatoid arthritis (RA) is an inflammatory disorder that primarily affects the synovial joints of the hands, feet, and cervical spine. This causes inflammation and pain in the joints and surrounding tissues. What is aponeurosis? c. the sarcoplasmic reticulum However, ball-and-socket joints allow for large movements, while the motions between bones at a plane joint are small. In a hinge joint, the convex end of one bone articulates with the concave end of the adjoining bone (see Figure 9.4.3b). At a condyloid joint (ellipsoid joint), the shallow depression at the end of one bone articulates with a rounded structure from an adjacent bone or bones (see Figure 9.4.3e).

Tubules that allow electrical impluses to travel into the muscle cell Here, the head of the radius is largely encircled by a ligament that holds it in place as it articulates with the radial notch of the ulna. The second movement is a side-to-side movement, which allows you to spread your fingers apart and bring them together, or to move your hand in a medial or lateral direction. Gleno-humeral joint is a ball and socket joint. All synovial joints have a joint cavity filled with synovial fluid that is the site at which the bones of the joint articulate with each other. As forces acting on a joint increase, the body will automatically increase the overall strength of contraction of the muscles crossing that joint, thus allowing the muscle and its tendon to serve as a "dynamic ligament" to resist forces and support the joint. This patient also had crystals that accumulated in the space next to his spinal cord, thus compressing the spinal cord and causing muscle weakness. B 7, 5, 3 B growth hormone increases mitosis The epimysium extends past the muscle and merges with the epimysium of the other muscle.
