1 1. Make a drawing of a synovial joint and label at least 3 parts 2. Make a list of the six types of synovial joints and indicate the movements allowed by each type Six Types of Synovial Joints Movement Saddle Joints This joint is biaxial and has a concave surface in one direction and convex in another. It can move back and forth or side to side. Ball-and-Socket Joint The body’s only multiaxial joint allowing movement in all rotations and planes. The round head articulates with a cup-shape cavity. Condyloid (Ellipsoid) joint An oval convex surface on one bone articulates with a depressed elliptical cavity. The is a biaxial joint that allows for movement in the sagittal and frontal plane. But no rotation.

2 Plane (Gliding) joint Surfaces are flat and slightly concave and convex. This joint is allowing for biaxial movements such as a sliding or twisting motion. Hinge Joint Bone surface articulate with a concave surface. This joint is monaxial that causes flexion and extension. Pivot Joint Cylinder shaped bones articulates. This joint is monaxial as they rotate around a central axis. 3. Make a drawing of a long bone and label at least 3 different areas 4. Make a drawing of an osteon and label lacunae, osteocyte, and central canal.

7 The three types of cartilages are hyaline, elastic, and fibrous and all three of these cartilages are connective tissue. Hyaline cartilage has a clear glassy matrix due to the thinness of its collagen fibers and its usually covered by perichondrium. It can be found between the tips of ribs and the sternum as well as covering the surfaces of bone at synovial joints. It allows for stiff but flexible support in addition to easing the friction between bony surfaces. Elastic cartilage has the appearance of a web-like mesh always surrounded by perichondrium like hyaline. It can be found in the auricle of the external ear or the epiglottis. Like hyaline, Elastic cartilage is flexible but it can be distorted and still return to its original shape without damage. Finally,

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
