The video shows a close-up of a model of a human knee joint. The model is made of plastic and is colored to represent the different parts of the knee. The femur, tibia, and patella are clearly visible. The femur is the thigh bone, the tibia is the shin bone, and the patella is the kneecap. The model is shown from various angles to give a comprehensive view of the knee joint. The video also includes text overlays that label the different parts of the knee, such as the quadriceps tendon and patellar tendon. The video is likely used for educational purposes to teach anatomy and physiology.
