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 fibularis longus arises from the head and upper two-thirds of the lateral, or outward, surface of the fibula, from the deep surface of the fascia, and from the connective tissue between it and the muscles on the front and back of the leg. It occasionally is also connected by a few fibers from the lateral condyle of the tibia.
The short head originates from the middle third of the linea aspera on the shaft of the femur and the lateral intermuscular septum of thigh, and acts on only one joint. These two heads unite to form the biceps which inserts on the head of the fibula. The biceps flexes the knee joint and rotates the flexed leg laterally—it is the only lateral ...
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". (It is cognate with mallet.)
In the leg, the syndesmosis between the tibia and fibula strongly unites the bones, allows for little movement, and firmly locks the talus bone in place between the tibia and fibula at the ankle joint. This provides strength and stability to the leg and ankle, which are important during weight bearing.
The bony architecture of the ankle consists of three bones: the tibia, the fibula, and the talus. The articular surface of the tibia may be referred to as the plafond (French for "ceiling"). [10] The medial malleolus is a bony process extending distally off the medial tibia. The distal-most aspect of the fibula is called the lateral malleolus ...
The tibia (/ ˈ t ɪ b i ə /; pl.: tibiae / ˈ t ɪ b i i / 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); it connects the knee with the ankle.
The term fibula eventually became the standard name for the bone, but many of the related arteries, muscles, and nerves are still called by the Greek derived name peroneal. The Terminologia Anatomica , the international standard for anatomical nomenclature, states that both fibula and perone derived names are acceptable, but lists the fibula ...
