Crus

Crus refers to the part of the lower limb in humans and other animals, also known as the leg. In human anatomy, the term "crus" is used to describe the portion of the body that includes the tibia and fibula, bones of the lower leg.

Anatomy

The crus is the part of the leg that lies between the knee joint and the ankle joint. It is composed of two bones: the tibia and the fibula. The tibia is the larger of the two bones and is located medially. The fibula, on the other hand, is the smaller bone and is located laterally.

Tibia

The tibia is the second largest bone in the human body and is responsible for bearing most of the body's weight. Its upper part forms the lower part of the knee joint, while its lower part forms the upper part of the ankle joint.

Fibula

The fibula is a long, thin bone that runs parallel to the tibia. It forms the outer part of the ankle joint and provides stability to the leg.

Clinical significance

Injuries to the crus, such as fractures, can be serious and may require medical intervention. Treatment options depend on the severity of the injury and can range from immobilization to surgery.
