térdkalaps
The térdkalaps, also known as the kneecap or patella, is a small, triangular bone located at the front of the knee joint. It is a sesamoid bone, meaning it is embedded within a tendon, in this case, the quadriceps femoris tendon. Its primary function is to increase the leverage of the quadriceps muscle, thereby improving the efficiency of knee extension. The térdkalaps glides within a groove at the end of the femur called the trochlear groove. This smooth articulation allows for effortless movement of the leg during activities such as walking, running, and jumping. The posterior surface of the térdkalaps is covered in articular cartilage, which facilitates its smooth movement against the femur. The térdkalaps is crucial for the proper functioning of the knee and can be affected by various injuries and conditions, including dislocations, fractures, and patellofemoral pain syndrome. Maintaining the strength and flexibility of the surrounding muscles, particularly the quadriceps and hamstrings, is important for supporting and protecting the térdkalaps and the knee joint as a whole.
