The greater the range of motion at a joint....................

– immovable joint; extremely strong joints; ex. - sutures

slightly movable joints; not as strong as a synarthrosis and permits less movement than a diathrosis; ex. - between the tibia and fibula, between the left and right halves of the pelvis, between the vertebrae

freely movable joints; synovial joint; articular capsule of the joint is lined with synovial membrane which produces synovial fluid (lubricant). synovial; ex. – elbow, knee,

based on degree of movement permitted within the joint; functional categories are further subdivided on the basis of the anatomical structure of the joint or the range of motion permitted

based on anatomical organization of the joint: presence or absence of a joint cavity and the kind of supporting connective tissue surrounding the joint

Function of joints:

Factors that are responsible to limiting the range of motion, stabilizing the joint, and reducing the chance of injury
