Articulations • Dictionary definition: a joint in the body; a point of contact between two or more bones • Examples: ankle, knee, hip, shoulder, elbow, carpal, vertebral
Synovial Joints(freely moveable joints like the knee) • 7 structures: 1. Joint Capsule: connective tissue connecting bones on the outside 2. Synovial Membrane: moist, slippery membrane lining the inner surface of the joint capsule (lubricates and nourishes surfaces) 3. Articular Cartilage: connective tissue covering joint surfaces of the bones
Synovial Joints Continued... 4. Joint Cavity: small space between bones allowing movement 5. Menisci: pads of cartilage located between the ends of bones which help prevent bones from grinding 6. Ligaments: strong cords of dense, white fibrous tissue connecting bones 7. Bursae: closed pillow-like structures filled with synovial fluid to cushion
