Skeletal System Gael Parra Period 5 - Coggle Diagram

- - - - Joint (synovial) cavity: small fluid-filled potential space that is unique to synovial joints
      - Articular (joint) capsules: Two layers thick and includes external and internal layers.
      - Articular Cartilage: consists of hyaline cartilage covering ends of bones
      - Synovial Fluid: Viscous slippery filtrate of plasma and hyaluronic acid
      - Reinforcing Ligaments: Capsular which are thickened parts of the fibrous layers. Extracapsular which is outside the capsule and intracapsular which are deep to the capsule.
      - Nerves and Blood Vessels: Nerves detect pain, monitor joint position and stretch. The capillary beds supply filtrate for synovial fluid.
    - - Synchondroses: When a bar or plate of hyaline cartilage unites the bone. Almost all of these cartilage are synarthrotic (immovable).
      - Symphysis: When fibrocartilage unites bone in the symphysis joint. Symphysis joints are strong amphiarthrotic joints which means they are slightly movable joints.
    - - Syndesmoses: Bones connected by ligaments, band of fibrous tissue. The length varies which means movement varies, shorter fibers offer less movement, while longer fibers offer more movement.
      - Sutures: Rigid interlocking joints of the skull. These fibrous joints allow from growth during youth and contain short connective tissue fibers that allow for expansion. The sutures ossify and fuse in the middle age and the joints become immovable and fully close.
      - Gomphases: These are peg-in-socket joints. The only examples of these are the teeth in the alveolar sockets and the fibrous connections are periodontal ligaments.
