What are three classifications of joints?
|
Fibrous (synarthrosis), cartilaginous, synovial(diathrosis)
|
|
|
What does being a synathroses joint mean? What are some examples?
|
Synathroses: Immovable. Two examples are sutural bones in the skull and the gomphosis which is the ligament that binds teeth into socket.
|
|
|
What does amphiarthoses mean and what is syndesmosis?
|
Amphiarthoses mean slightly movable. Syndesmosis is where bone connects through cartilage for example between tibia and fibula or radius and ulna.
|
|
|
What is symphysis?
|
Symphysis is the fibrocartilage that seperates bones. Ex.: pubic symphysis that holds together pelvic bones.
|
|
|
What is diathroses?
|
Freely movable. Possess cavity which is synovial cavity. Synovial joints allow a wide range of motion. For example at the end of long bones. Articulating surfaces are covered by hyaline cartilage.
|
|
|
What is a joint capsule?
|
A joint capsule surrounds synovial joints, lined by membrane which produces synovial fluid. Synovial fluid has three functions: lubrication, nourishes chondrocytes and is a shock absorber.
|
|
|
What are some accessory structures in the knee area?
|
Cartilage and fat pads. This includes menisci which are articular cartliages in the knee that are in the shape of a cresent. They absorb shock and pressre and stabilize knee joint. Tendons limit range of motion and provide support.
|
|
|
What are bursae?
|
Fluid-filled sacs between muscle or between muscle and bones that provides shock absorbers and reduces friction. Includes supra-patellar bursa, pre-patellar bursa and infra-patellar bursa. Bursitis is the inflammation of the bursae.
|
|
|
What are tendon sheaths?
|
Specialized bursae that wrap around tendons as they pass over bone. Tendonitis is inflammation of the tendon sheath.
|
|
|
Explain the three types of ligaments.
|
Accessory ligaments: Thickening of the joint capsule. Extracapsular: Outside of the joint capsule. Intracapsular: Inside the joint capsule.
|
|
|
What are the six classifications of synovial joints?
|
1.) Ball and socket joint(humeroscapular) 2.)Pivot Joint(radioulnar) 3.)Gliding Joint (Intercarpal) 4.)Condyloid joint(metacarpophalangeal) 5.)Saddle Joint (trapeziometacarpal) 6.)Hinge Joint (humeroulnar)
