Title: Tibia
Content:  The tibia (plural tibiae  or tibias), also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two bones in the leg below the knee in vertebrates (the other being the fibula, behind and to the outside of the tibia), and it connects the knee with the ankle bones. The tibia is found on the medial side of the leg next to the fibula and closer to the median plane or centre-line. The tibia is connected to the fibula by the interosseous membrane of leg, forming a type of fibrous joint called a syndesmosis with very little movement. The tibia is named for the flute tibia. It is the second largest bone in the human body next to the femur. The leg bones are the strongest long bones as they support the rest of the body.
Title: Fibula
Content:  The fibula or calf bone is a leg bone on the lateral side of the tibia, to which it is connected above and below. It is the smaller of the two bones and, in proportion to its length, the most slender of all the long bones. Its upper extremity is small, placed toward the back of the head of the tibia, below the knee joint and excluded from the formation of this joint. Its lower extremity inclines a little forward, so as to be on a plane anterior to that of the upper end; it projects below the tibia and forms the lateral part of the ankle joint.
Title: Tibia
Content:  In human anatomy, the tibia is the second largest bone next to the femur. As in other vertebrates the tibia is one of two bones in the lower leg, the other being the fibula, and is a component of the knee and ankle joints. The ossification or formation of the bone starts from three centers; one in the shaft and one in each extremity. The tibia is categorized as a long bone and is as such composed of a diaphysis and two epiphyses. The diaphysis is the midsection of the tibia, also known as the shaft or body. While the epiphyses are the two rounded extremities of the bone; an upper (also known as superior or proximal) closest to the thigh and a lower (also known as inferior or distal) closest to the foot. The tibia is most contracted in the lower third and the distal extremity is smaller than the proximal.
Title: Tubercle (bone)
Content:  ligament of the tubercle. The tubercle is much more prominent in the upper ribs than in the lower ribs. The most prominent tubercle of the tibia, a leg bone which is more commonly known as the shinbone or shankbone, is the tibial tuberosity. The tibial tuberosity is located on the tibia's anterior surface, distal to the medial condyle. It creates a bony prominence just below the patella, and can be easily located with the fingers. It creates an attachment point for the ligamentum patellae, or patellar ligament. Other tubercles of the tibia include the medial intercondylar tubercle, the lateral intercondylar tubercle, and Gerdy's tubercle. A trochanter is one of up to three tubercles of the femur:  In the fifth metatarsal bone, the most proximal part of the bone is termed the "tuberosity", and the secondary ossification center that is normally present thereon in children is termed the "apophysis".
Title: Fibular notch
Content:  The fibular notch of the tibia is an indentation at the inferior portion of the tibia where it articulates with the fibula to form the inferior tibiofibular articulation.
Title: Fibula
Content: Lateral malleolus ; Interosseous membrane connecting the fibula to the tibia, forming a syndesmosis joint ; The superior tibiofibular articulation is an arthrodial joint between the lateral condyle of the tibia and the head of the fibula. ; The inferior tibiofibular articulation (tibiofibular syndesmosis) is formed by the rough, convex surface of the medial side of the lower end of the fibula, and a rough concave surface on the lateral side of the tibia. The bone has the following components:
Title: Leg bone
Content: Femur – The bone in the thigh. ; Patella – The knee cap ; Tibia – The shin bone, the larger of the two leg bones located below the knee cap ; Fibula – The smaller of the two leg bones located below the knee cap  Leg bones are the bones found in the leg. These can include the following:
Title: Glyphoderma
Content:  The femur is expanded at both ends, but has a short shaft (only 59 mm). The space between the tibia and fibula is very large as the tibia has a straight medial edge and a concave lateral one. They are roughly the same length (47.5 mm fibula, 49.4 mm tibia). The calcaneum and astragalus form a depression for the distal end of the tibia to fit into. There are four other tarsals and four metatarsals, but it is very difficult to determine the phalangeal formula due to the poor preservation of the foot.
Title: Tibia
Content:  ligament of the head of the fibula. The distal tibiofibular joint (tibiofibular syndesmosis) is formed by the rough, convex surface of the medial side of the distal end of the fibula, and a rough concave surface on the lateral side of the tibia. The part of the ankle joint known as the talocrural joint, is a synovial hinge joint that connects the distal ends of the tibia and fibula in the lower limb with the proximal end of the talus. The articulation between the tibia and the talus bears more weight than between the smaller fibula and the talus.
Title: Tibia
Content:  on the posterior surface of the talus and serving for the passage of the tendon of the Flexor hallucis longus. The lateral surface presents a triangular rough depression for the attachment of the inferior interosseous ligament connecting it with the fibula; the lower part of this depression is smooth, covered with cartilage in the fresh state, and articulates with the fibula. The surface is bounded by two prominent borders (the anterior and posterior colliculi), continuous above with the interosseous crest; they afford attachment to the anterior and posterior ligaments of the lateral malleolus. The medial surface -- see medial malleolus for details.

Question: where is the tibia and fibula bone located?
Answer: leg.
