Week 7 Lab: Joints Natasha Ngong Chamberlain University College of Nursing BIOS 251: Anatomy and Physiology Lab Professor Zille June 24, 2024 Week 7 Lab: Joints Analysis of Joints: Select the synovial joints and follow these steps to analyze all the structures listed below. Femur: It is the body's longest and strongest bone and is essential for standing, walking, and supporting muscles, tendons, ligaments, and the circulatory system. Tibial collateral ligament: This is a broad, strong band that primarily stabilizes the knee joint in the coronal plane on the medial side. Joint capsule: Its purpose is to support the joint, distribute the biomechanical load, and protect it by limiting its normal range of motion. Suprapatellar bursa: It allows unrestricted movement of the quadriceps tendon over the distal femur. Tibia: As the second-largest bone in the body, the tibia's primary role in the leg is to carry weight, bearing most of the load. Medial meniscus: The medial meniscus's primary function is to reduce the amount of stress on the knee joint. 202564-173425Suprapatellar bursa 5779135222852Femur Femur Joint capsules Tibial collateral ligament Medial meniscus Tibia Use the layer controls to remove/add layers ending on layer 10 and rotation controls to rotate the model to frame 9 for the following structures. Synovial fluid: It minimizes friction between the articular cartilages of synovial joints during movement. Patella: It protects the knee joint, lengthens the lever arm of the quadriceps femoris, and increases the area of contact between the patellar ligament and the femur. Patellar ligament: The patellar ligament interacts with the muscles in the front of your thigh to the knee's extensor mechanism. Articular hyaline cartilage: It provides a smooth, lubricated surface for low friction articulation and facilitates load transmission to the underlying subchondral bone. Fat pad: In the event of a direct strike to the front of the knee, it acts as a shock absorber, cushioning the patella and preventing it from hitting the femur (thigh bone). 107315431482500 Synovial fluid Articular hyaline cartilage Patella Patellar ligament Fat pad Part B: Read the case study. In your own words and in complete sentences answer the questions: John, a 75-year-old man, was diagnosed with osteoarthritis in his knee five years ago. Recently his condition worsened and so decided to see a doctor. John’s doctor ordered a radiograph imaging to visualize his knee joint. What is osteoarthritis? What symptoms will John experience? Osteoarthritis is a degenerative joint disease that causes cartilage breakdown, and the symptoms John will experience are joint pain, stiffness, tenderness, loss of flexibility, grating sensations, and swelling. What type of joint is the knee? The knee is a hinge-type synovial joint that primarily allows flexion and extens
