Where in your body is your patella

Answer
Kneecap

The patella (/pəˈtɛlə/), also known as the kneecap or kneepan, is a thick, circular-triangular bone which articulates with the femur (thigh bone) and covers and protects the anterior articular surface of the knee joint.

The patella is found in most vertebrates such as mice, cats, and birds, but not in whales or most reptiles and amphibians such as snakes or frogs.

In humans, the patella is the largest sesamoid bone in the body. Babies are born with a patella of soft cartilage which begins to ossify into bone at about three years of age.
