The patella, also known as the kneecap, is a flat, 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 many tetrapods, such as mice, cats and birds, but not in
whales, or most reptiles.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 four years of
age.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 four years of age.The patella is a sesamoid
bone roughly triangular in shape, with the apex of the patella facing
downwards. The apex is the most inferior (lowest) part of the patella.
It is pointed in shape, and gives attachment to the patellar
ligament.The front and back surfaces are joined by a thin margin and
towards centre by a thicker margin. The tendon of the quadriceps
femoris muscle attaches to the base of the patella., with the vastus
intermedius muscle attaching to the base itself, and the vastus
lateralis and vastus medialis are attached to outer lateral and medial
borders of patella respectively. Patella Top Movies & Young Movies
