Joint Structure and Movements19Laboratory ExercisePurpose of the ExerciseTo examine examples of the three types of structural andfunctional joints, to identify the major features of thesejoints, and to review the types of movements produced atsynovial joints.Materials NeededHuman skullHuman skeleton, articulatedModels of synovial joints (shoulder, elbow, hip,and knee)For Demonstration Activities:Fresh animal joint (knee joint preferred)Radiographs of major jointsSafetyPre-LabCarefully read the introductory material and examinethe entire lab. Be familiar with joint structures andmovements from lecture or the textbook.Visit for LabCamvideos. Answer the pre-lab questions.Pre-Lab Questions:Select the correct answer foreach of the following questions:1.Fibrous joints are structural types containinga.cartilage.b.dense fibrous connective tissue.c.synovial membranes.d.synovial fluid.2.Which synovial joint allows movements in allplanes?
