Joints

Components of a joint • Bones • Muscles • Connective tissues • Ligaments • Tendons • Cartilage • Other?

Connective Tissues in Joints • Ligament = fibrous connective tissue that connects a bone to a bone • Holds structures together • Keeps structures stable • Tendon = fibrous connective tissue that connects a muscle to a bone (or a muscle to a structure – ex. Eyeball) • Moves the bone or structure • Cartilage = resilient, smooth, elastic tissue that cushions space between bones in joints

Bones of the Knee Joint • • Femur Patella Tibia Fibula

• Vastus lateralis • Quadriceps tendon • Iliotibial band • Lateral Retinaculum • Vastus medialis obliquus • Medial retinaculum • Articular capsule • Patellar ligament

Ligaments of the Knee • Anterior cruciate ligament (ACL) • Posterior cruciate ligament (PCL) • Lateral collateral ligament (LCL) • Medial collateral ligament (MCL) • Lateral meniscus • Medial meniscus

• Quadriceps connects to the patella • Hamstring connects to the tibia • Calf connects to the femur

Research a synovial joint • Gliding • Hinge • Pivot • Condyloid • Saddle • Ball and socket 1. Find two partners 2. Choose a type of joint (out of a hat) 3. Quick research 1. Find several examples of the type of joint in the human body 2. Find all the parts of the joint (bones, tendons, ligaments, muscles, cartilage) 3. Discover how those parts work together 4. Quick presentation prep 1. Prepare a few slides to show to the class 2. Use lots of images 5. Explain how the joint works to the class
