Artery Supplying the Tibia (A. Nutricia Tibiae, Bna, Jna)

The artery supplying the tibia is also called a. nutricia tibia, bna and jna (from the Latin “nutricia” - nutrition, and “tibia” - tibia). This is one of the branches of the external iliac artery (a. iliaca externa), which passes through the inguinal canal and further to the knee joint.

A. nutricia tibia is a branch of the external iliac artery. It supplies blood to the muscles, tendons and joints of the knee joint, and also provides nutrition to the tibia. A. nutricia tibia emerges from the external iliac artery at the level of the lower edge of the pubic bone and goes down to the medial surface of the knee joint.

The artery has three branches: lateral, medial and anterior. The lateral branch runs parallel to the lateral condyle of the tibia and supplies it and the muscles and tendons of the posterior thigh. The medial branch runs medial to the lateral and supplies the tendons of the anterior thigh and the medial condyle of the tibia. The anterior branch, the shortest, runs forward and upward to the front of the knee joint and supplies the anterior cruciate ligament.

In addition, a. nutricia tibia may have additional branches that provide nutrition to other structures of the knee joint. For example, it can give off a branch to the anterior cruciate ligament or to the capsule of the knee joint. These branches may be important for healing and recovery after knee injuries or other knee surgeries.

Thus, the artery supplying the tibia plays an important role in the blood supply to the knee joint and provides nutrition to its structures. Knowing the anatomy of this artery can help doctors and surgeons better understand and treat injuries and diseases of the knee joint.

It is palpated on the dorsum of the foot under the skin, superficial to its own artery. Branches: 1. the knee branch (ramus genu) is divided into anterior and posterior tarsal branches.
