The lower limb is subdivided by the hip joint, knee joint, and ankle joint into the regions:buttock (gluteal), thigh, leg (crus), foot. The movements which occur at the hip joint are similar to those that take place at the shoulder joint except their range is more limited. Those at the knee joint occur mainly in one plane. When the knee is bent, it is said to be flexed; when it is straightened out it is extended. There is a small amount of rotation at the joint. The ankle joint is a simpler hinge type joint than the knee. When the foot is bent upwards, it is dorsiflexed or extended; when it is bent downwards, it is plantar flexed or flexed. Through the joints within the foot, the foot can be turned so that the sole of the foot is inwards, inversion or it can be turned so that the sole is turned outwards, eversion. The toes have limited movement when compared to the movements of the fingers, especially the thumb.
