Leg bones are the bones found in the leg. These can include the following: 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 patella
The major bones of the leg are the femur (thigh bone), tibia (shin bone), and adjacent fibula, and these are all long bones. The patella (kneecap) is the sesamoid bone in front of the knee. Most of the leg skeleton has bony prominences and margins that can be palpated and some serve as anatomical landmarks that define the extent of the leg.
There are a total of 8 bones in the legs and 52 in the feet. Femur (2) Patella or kneecap (2) Tibia (2) Fibula (2) Foot (52 bones in total, 26 per foot) Tarsus. Calcaneus or heel bone (2) Talus (2) Navicular bone (2) Medial cuneiform bone (2) Intermediate cuneiform bone (2) Lateral cuneiform bone (2) Cuboid bone (2) Metatarsals (10)
The fibula (pl.: fibulae or fibulas) 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.
The tuberosity of the tibia gives attachment to the patellar ligament, which attaches to the patella from where the suprapatellar ligament forms the distal tendon of the quadriceps femoris muscles. The quadriceps muscles consist of the rectus femoris , vastus lateralis , vastus medialis , and vastus intermedius .
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 lateral malleolus is the prominence on the outer side of the ankle, formed by the lower end of the fibula. The word malleolus ( / m ə ˈ l iː ə l ə s , m æ -/ [ 1 ] [ 2 ] ), plural malleoli ( / m ə ˈ l iː ə ˌ l aɪ , m æ -/ ), comes from Latin and means "small hammer ".
The patella is found in many tetrapods, such as mice, cats, birds and dogs, but not in whales, or most reptiles. In humans, the patella is the largest sesamoid bone (i.e., embedded within a tendon or a muscle) in the body. Babies are born with a patella of soft cartilage which begins to ossify into bone at about four years of age.
