Document Summary

Study of joint structure, function and dysfunction. Attached bone to bone: dense regular connective tissue. Tubes wrapped around tendons, especially hand and foot. Increases circulation > warms synovial fluid > increased absorption by cartilage. Cartilage swells > increases protection against compression (decreases wear and tear . Exercise improves nutrition, oxygenation, and waste removal of chondrocytes > healthier tissue. Builds bone and strengthens muscles which strengthens and stabilizes joints. Number of degrees through which one bone moves relative to another at that joint. Structure of the articular surfaces of the bone. Strength and tautness of ligaments and the joint capsules. Movement of synovial joints (need to know for test) Right of left rotation of appendicular skeleton. Lateral or medial rotation of appendicular skeleton. Abduction - movement away from the body. Adduction - movement towards the body (adding it to the body) Elevation - to raise (close the mouth) Depression - to unraise (open the mouth)
