Bones of the Leg and Foot:
1. Femur or thigh bone. Femur is the longest bone in the human body. This bone has a round-shaped head like structure at its proximal. This head called femoral head mounts into a socket like depression in the hip bone called acetabulum. The acetabulum was termed for the reason that of its likeness to a rounded cup.
2. Kneecap or patella. This bone is a flat in size and small in structure. Patella is positioned in face of the articulation sandwiched between the femur or thigh bone and one of the lower leg bones called the tibia. Patella is enclosed or bounded by shielding tendons and seized in position by muscle attachments.
3. Tibia or shin bone. Tibia means a music instrument called flute, as this bone resembles that. Tibia are the largest bones in the legs. Each tibial bone is present under the skin. Tibial bones are in front of the leg. Each tibia joins with the femur bones in each leg at the patella distally with the ankle. A bony prominence called malleolus is formed by the joining of these bones at the ankle.
4. Fibula. These bones are smaller in structure and two in number. Fibular bone is hidden under the leg muscle. It joins at its proximal end with the tibia crossways and also joins at distal end with the tibia and ankle bones. These to form the bony prominence called lateral malleolus on the outside of the ankle.
5. Tarsal bones. These bones are seven in number. The bones are called ankle bones. These bones resemble the carpal bones of the wrist, but are larger. The calcaneus is the largest bone of these seven bones. Another name of these bones is heel bones.
6. Metatarsals. The bones are five in number. Each metatarsal bone leads to the phalanges of the toes.
7. Phalanges of the toes. These bones are five in number. The two phalanges in the big toe and three bones in the other four toes of the foot.
