Ancient Roman wind instrument, similar to the Greek Aulos, consisting of two pipes, sometimes with bell extensions to increase the volume. It was used by the Etruscans and Romans in religious ceremonies and rituals, was prominent in Roman literature and played an important part in the theatre.



 

shin bone

The inner and larger bone in the lower leg extending from the ankle to the knee. It articulates with the talus below and the femur above. It is triangular in cross-section. The sharp anterior crest and medial surface of the tibia are unprotected by muscle and can be felt just underneath the skin.

The inner and larger bone of the hindlimb below the stifle; it articulates with the femur and head of the fibula above and with the talus below.

  • rotated t. — a disease of young turkeys characterized by rotation of the shaft of the tibiotarsus of one leg causing the metatarsus to point laterally and the bird to assume a spraddle leg posture. Up to 15% of a flock may be affected.
  • t. valga — a bowing of the leg in which the angulation is away from the midline of the body.

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.

Contents

In humans

The tibia is found medial and anterior to the fibula. It is the second largest bone in the human body, the largest being the femur. The tibia articulates with the femur and patella superiorly, the fibula laterally and with the talus inferiorly.

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 obliqueness 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 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 tibia is connected to the fibula by an interosseous membrane, forming a type of joint called a syndesmoses.

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
