Fibula. 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. Its upper extremity is small, placed toward the back of the head of the tibia, below the ...
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, after the femur. The leg bones are the strongest long bones as they support the rest of the body.
Articular surfaces of femur Articular surfaces of tibia. The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations linking the femur, or ...
In human anatomy, the lower leg is the part of the lower limb that lies between the knee and the ankle. [5] Anatomists restrict the term leg to this use, rather than to the entire lower limb. [6] The thigh is between the hip and knee and makes up the rest of the lower limb. [5] The term lower limb or lower extremity is commonly used to describe ...
Tibialis posterior muscle. The mucous sheaths of the tendons around the ankle. Medial aspect. (Tibialis posterior labeled at top center.) The tibialis posterior muscle is the most central of all the leg muscles, and is located in the deep posterior compartment of the leg. It is the key stabilizing muscle of the lower leg.
A malleolus is the bony prominence on each side of the human ankle. Each leg is supported by two bones, the tibia on the inner side (medial) of the leg and the fibula on the outer side (lateral) of the leg. The medial malleolus is the prominence on the inner side of the ankle, formed by the lower end of the tibia.
The soleus is located in the superficial posterior compartment of the leg. The soleus exhibits significant morphological differences across species. It is unipennate in many species. In some animals, such as the rabbit, it is fused for much of its length with the gastrocnemius muscle. The soleus is a complex, multi-pennate muscle in humans ...
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 ...
