Chapter 8: Joints Articular cartilage Articulating bone Fibrous membrane Periosteum Synovial (joint) cavity Synovial membrane Figure LG 8.1 Structure of a generalized synovial joint. Color as directed in Checkpoint A7. A7. On Figure LG 8.1, color the indicated structures. A8. Select the parts of a synovial joint (listed in the box) that fit the descriptions below. A. Articular cartilage FM. Fibrous membrane L. Ligaments SF. Synovial fluid SM. Synovial membrane a. Hyaline cartilage that covers ends of articulating bones but does not bind them together b. With the consistency of uncooked egg white or oil, it lubricates the joint and nourishes the avascular articular cartilage c. Connective tissue membrane that lines synovial cavity and secretes synovial fluid d. Parallel fibers in some fibrous capsules; bind bones together e. Together these form the articular capsule (two answers) f. Provides both flexibility and tensile strength g. Reduces friction at the joint h. Contains phagocytes that remove debris and microbes from joint i. Structures that are more flexible than usual in persons who are "double-jointed" (three answers) A9. Describe the role played by synovial fluid in each of the following scenarios: a. Tiffinee always warms up before she exercises b. Amalie drives her sister crazy by cracking her knuckles all evening.

Part II. Joint classification tree: Place each of the terms below in the appropriate box Synovial Multiaxial Gomphosis Syndesmosis Pivot Synchondrosis Cartilaginous Saddle Biaxial Uniaxial Plane/gliding Joints Fibrous All Suture Symphysis diarthrotic Strong Ball & socket Plane Hinge Condylar Uniaxial Biaxial Part III: Draw a synovial joint: Label each structure, indicate the type of tissue(s) it is composed of, and the primary function of the structure. Also indicate where the synovial fluid-filled joint space would be located. Be sure to include: Bones, fibrous capsule, articular cartilage, synovial membrane (synovium), ligaments, meniscus.
Watch this video (http://openstaxcollege.org 11 synjoints) to see an animation of synovial joints in action. Synovial joints are places where bones articulate with each other inside of a joint cavity. The different types of synovial joints are the ball-and-socket joint (shoulder joint), hinge joint (knee), pivot joint (atlantoaxial joint, between $\mathrm{C} 1$ and C2 vertebrae of the neck), condyloid joint (radiocarpal joint of the wrist), saddle joint (first carpometacarpal joint, between the trapezium carpal bone and the first metacarpal bone, at the base of the thumb), and plane joint (facet joints of vertebral column, between superior and inferior articular processes). Which type of synovial joint allows for the widest ranges of motion?
