Document Summary
Bones: provide a frame (shape) to keep the body supported. Help to produce movement with the aid of the muscles. Bursa: it provides a cushion between bones and tendons and/or muscles around a joint (i. e, shoulder or patella). Cartilage: a layer of resilient layer in the synovial joints that covers the surface of opposing bones. Joints: is the place of union of two or more bones. Joints are functional units because they permit adls. Synovial joints: freely movable because they have bones that are separated from each other and enclosed in a joint cavity. The cavity is filled with a lubricant called synovial fluid, the principal role of synovial fluid is to reduce friction between the articular cartilage of synovial joints during movement. The movements possible with synovial joints are: abduction, adduction, extension, flexion, rotation. Muscles: skeletal muscles are attached to bone by a tendon. Tendon: is a tough band of fibrous connective tissue that usually connects muscle to bone.
