Lower Limb
The lower limbs consist of the hip, butts, leg, thighs, calves, lower leg, knee, ankle, foot, heel, and toes.
Buttock
The butts are a mass of glutes or glute muscles covered by a thick layer of fat.

Lower Leg
The lower leg is located between the knee and ankle, involving bones such as the tibia and fibula. The muscle enclosing the back of the lower leg is called a calf.
Thigh
It is the area between the abdomen and the knee. The bone in the thigh is called Femur  and it is very thick and known as the longest bone in the body. The bone is in the structure of the ball and socket located below between the hip and the joint at the knee.
Knee
It is the lower joint connecting the femur bone and the tibia. The knee is made of two separate joints named femoral-patellar and femoral tibial joints. The femoral-patellar joint has a patella or kneecap and the groove of the kneecap on the front side of the femur helps in sliding whereas the femoral-tibial joint connects the femur, and thigh bone with the tibia and the main bone to the lower leg. The knee also consists of cartilage tissue that prevents the rubbing of bones on each other, hence called the Menisci.
Ankle
It is the joint that formed between the foot and the lower leg. The ankle is a hinge joint that links the distal end of the tibia and fibula in the lower leg with the proximal end of the talus bone in the foot.
The foot is made to bear the weight of the whole body. They do have five toes and the bottom of the foot is called the sole. The ball in the foot is a place where the toes are attached.
