MeSH	Tibia

The tibia, shinbone, or shankbone is the larger and stronger of the two bones in the leg below the knee in vertebrates and connects the knee with the ankle bones. Introduction ( classes Long bones body or Diaphysis Medullary canal Medical Subject Headings ( MeSH) is a huge Controlled vocabulary (or metadata system for the purpose of indexing journal articles and books Bones are rigid organs that form part of the Endoskeleton of Vertebrates They function to move support and protect the various organs of the body produce A leg is a limb on an Animal 's Body that supports the rest of the animal above the ground between the Ankle and the Hip and is used for The knee is the lower extremity Joint connecting the Femur, Patella, and the Tibia.

In humans

The tibia is found medial and anterior to the fibula. For other uses see Fibula (disambiguation The fibula or calf bone is a Bone located on the lateral side of the Tibia It is the second-longest bone in the human body, the largest being the femur. The femur is the thigh bone In Humans, it is the longest, most voluminous and strongest Bone. The tibia articulates with the femur and patella superiorly, the fibula laterally and with the talus inferiorly. The femur is the thigh bone In Humans, it is the longest, most voluminous and strongest Bone. The patella or kneecap is a thick triangular Bone which articulates with the Femur and covers and protects the knee joint For other uses see Fibula (disambiguation The fibula or calf bone is a Bone located on the lateral side of the Tibia See Talus for other meanings of the word The talus bone or astragalus of the Ankle joint connects the leg to the foot

Gender differences

In the male, its direction is vertical, and parallel with the bone of the opposite side. In the female, it has a slightly oblique direction downward and lateralward, to compensate for the greater obliquity of the femur.

Structure

It is prismoid in form, expanded above, where it enters into the knee-joint, contracted in the lower third, and again enlarged but to a lesser extent below.

The superior tibiofibular articulation is an arthrodial joint between the lateral condyle of the tibia and the head of the fibula. The superior tibiofibular articulation is an Arthrodial Joint between the Lateral condyle of the Tibia and the head of the Fibula A gliding joint ( arthrodial joint, plane articulation) is a Synovial joint which admits of only Gliding movement A joint is the location at which two or more Bones make contact For other uses see Fibula (disambiguation The fibula or calf bone is a Bone located on the lateral side of the Tibia The inferior tibiofibular articulation (tibiofibular syndesmosis) is formed by the rough, convex surface of the medial side of the lower end of the fibula, and a rough concave surface on the later side of the tibia. The inferior tibiofibular articulation ( tibiofibular syndesmosis) is formed by the rough convex surface of the medial side of the lower end of the Fibula, and a For other uses see Fibula (disambiguation The fibula or calf bone is a Bone located on the lateral side of the Tibia The tibia is connected to the fibula by an interosseous membrane, forming a type of joint called a syndesmoses. An interosseous membrane is a broad and thin plane of fibrous tissue that separates many of the Bones of the body Syndesmoses are Joints at which two bones are bound together by a Ligament only

Blood supply

The tibia derives its arterial blood supply from two sources:^[1]

1. the nutrient artery (main source)
2. periosteal vessels derived from the anterior tibial artery
