Q:

What is the function of the tibia?

A:

Quick Answer

Functions of the tibia, also called the shinbone, include connecting the knee to the ankle in the bodies of humans and other vertebrates. The tibia bone also functions to form part of the skeleton in the lower leg, where it supports movement of the leg, creates a point where muscles are inserted, stores minerals and produces blood cells in bone marrow. Vertebrate bodies contain one tibia bone in each leg.

Full Answer

The tibia bears the most weight of any bone in the body, although it is the smallest of the two bones in the lower leg. The bone bears a force up to 4.7 times body weight during walking. The larger fibula bone sits behind the tibia.

Medical conditions that can negatively impact the tibia include bone cancer, osteoporosis, dislocations, infections and fractures. Fractures include those that involve only the tibia and those that involve the tibia and the fibula. Fractures involving only the tibia are the Segond fracture, Gosselin fracture and Bumper fracture.

The tibia is classified as a long bone. It contains a diaphysis and two epiphyses. The diaphysis constitutes the middle of the tibia, while the epiphyses are rounded sections on the ends of the bone. Four joints include the tibia bone: the ankle, knee and interior and superior tibiofibular joints.

  • Q:

    How do the bones that comprise the knee joint fit together?

    A:

    The tibia, patella and femur are joined together at the knee to form a hinge joint, according to WebMD. The bones are held in place at the knee with an elaborate system of ligaments, and they are buffered from each other by thick pads of cartilage.

  • Q:

    Where is the shin located on the body?

    A:

    The human shinbone, also called the tibia, resides in the lower leg. Humans have two tibias as well as two fibulas, which are the second of two long bones that connect the knee to the ankle. The tibia is larger than the fibula and is found on the interior part of the lower leg, while the fibula is located on the outside.

  • Q:

    Is the knee proximal to the ankle?

    A:

    The knee is proximal to the ankle, and the ankle is distal to the knee. Proximal and distal are both anatomical words of location. Proximal means nearer to the point at which the structure originates or attaches, while distal means further from those points.

  • Q:

    What is the anatomy of the knee?

    A:

    The kneecap, also called the patella, is found in front of the knee joint, which is the junction between the femur, the upper leg bone, and the tibia, the lower leg bone. Flanking the kneecap are the medial epicondyle of the femur and the lateral epicondyle of the femur. Just beneath them are the lateral condyle and the medial condyle of the femur.
