It is formed by the lower part of the femur, the tibial plateau and the knee cap. It enables hinge and rotating movements as the connection between the upper and lower leg. This means that we can not only bend the lower leg backward but also rotate the lower leg and foot towards the upper leg.

Age 4-7 Months. From 4-7 months of age, babies learn to coordinate their new perceptive abilities (including vision, touch, and hearing) and motor skills such as grasping, rolling over, sitting up, and may be even crawling. Babies now have more control over what they will or will not do, unlike earlier months in which they mainly reacted by reflex.
