17. Related Joint Structures • Ligaments • Fibrocartilage • Occupies the space between ________________ ______________and can take on many sizes and shapes • Is __________ and are know as disks (e.g. those between the vertebrae of the spine), while others are flat or circular in shape (e.g. knee) • Is resilient and functions as the shock absorber • Not blood supply of its own and relies on synovial fluid for nourishment

18. Synovial Membrane • A thin tissue that surrounds most freely moving joints • Membrane secretes synovial fluid which provides nourishment for cartilaginous disks, lubrication, and hydrostatic cushioning • Joint Capsule • Bursae • Others (found in some joints): articular discs, fibrocartilaginous labra, meniscus and intracapsular tendons
