What is the anatomic name for the bone commonly known as the kneecap?

The anatomic name for the kneecap is the patella. This bone is a small, flat, triangular bone that is situated at the front of the knee joint. The patella serves several important functions, including protecting the knee joint, acting as a fulcrum for the quadriceps muscles, and enhancing the leverage of the muscle forces exerted on the lower leg. Its location and structure make it crucial for proper knee movement and stability during activities such as walking, running, and jumping.

In comparison, the tibia and fibula are long bones located in the lower leg and are responsible for bearing weight and providing structural support to the leg. The femur is the thigh bone, which is the longest bone in the body and connects the hip to the knee. Each of these bones plays a vital role in the overall function of the leg, but only the patella is specifically referred to as the kneecap.
