important connective tissues that work with bones to provide the support framework of the skeleton. Cartilage, Tendons, and Ligaments
Plates of shiny connective tissue that are surrounded by the perichondrium and lubricated by synovial fluid to provide a slippery surface over which bones may move freely. Cartilage
Transparent viscous joint fluid that is secreted by the synovial membrane. Synovial fluid
A double-layered connective tissue membrane that surrounds the cartilage. Perichondrium.
Specialized tough cords or bands of dense white connective tissue that Connects muscles to bones.Continuous with the periosteum of the bone. Tendons.
Double-layer membrane that covers all bones except the articular surfaces. Periosteum.
Composed of densely packed fibers of collagen. Tendons.
A twisted, rope-like protein. Collagen
