Tibia

The tibia, also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two bones in the leg below the knee in vertebrates, and it connects the knee with the ankle bones. The tibia is found on the medial side of the leg next to the fibula and closer to the median plane or centre-line. The tibia is connected to the fibula by the interosseous membrane of the leg, forming a type of fibrous joint called a syndesmosis with very little movement. The tibia is named for the flute tibia. It is the second largest bone in the human body next to the femur. The leg bones are the strongest long bones as they support the rest of the body.

Extensor hallucis longus muscle A thin muscle, situated between the tibialis anterior and the extensor digitorum longus

The extensor hallucis longus is a thin muscle, situated between the tibialis anterior and the extensor digitorum longus, that functions to extend the big toe and dorsiflects the foot, and assists with foot eversion and inversion.

Tibialis posterior muscle Muscle in the most central of all the leg muscles

The tibialis posterior is the most central of all the leg muscles, and is located in the deep posterior compartment of the leg.

Tibialis anterior muscle Muscle in humans that originates along the upper two-thirds of the lateral surface of the tibia

The tibialis anterior is a muscle in humans that originates along the upper two-thirds of the lateral (outside) surface of the tibia and inserts into the medial cuneiform and first metatarsal bones of the foot. It acts to dorsiflex and invert the foot. This muscle is mostly located near the shin.

The anterior tibial artery of the leg carries blood to the anterior compartment of the leg and dorsal surface of the foot, from the popliteal artery.

Tibial nerve

The tibial nerve is a branch of the sciatic nerve. The tibial nerve passes through the popliteal fossa to pass below the arch of soleus.

Flexor hallucis longus muscle One of the three deep muscles of the posterior compartment of the leg that attaches to the plantar surface of the distal phalanx of the great toe

The flexor hallucis longus muscle (FHL) is one of the three deep muscles of the posterior compartment of the leg that attaches to the plantar surface of the distal phalanx of the great toe. The other deep muscles are the flexor digitorum longus and tibialis posterior; the tibialis posterior is the most powerful of these deep muscles. All three muscles are innervated by the tibial nerve which comprises half of the sciatic nerve.

Flexor digitorum longus muscle Muscle located on the tibial side of the leg

The flexor digitorum longus is situated on the tibial side of the leg. At its origin it is thin and pointed, but it gradually increases in size as it descends. This muscle serves to curl the second, third, fourth, and fifth toes.

Extensor digitorum longus muscle A pennate muscle, situated at the lateral part of the front of the leg

The extensor digitorum longus is a pennate muscle, situated at the lateral part of the front of the leg.

Deep peroneal nerve

The deep peroneal nerve begins at the bifurcation of the common peroneal nerve between the fibula and upper part of the peroneus longus, passes infero-medially, deep to extensor digitorum longus, to the anterior surface of the interosseous membrane, and comes into relation with the anterior tibial artery above the middle of the leg; it then descends with the artery to the front of the ankle-joint, where it divides into a lateral and a medial terminal branch.

Anterior tibial may refer to:

Inferior extensor retinaculum of foot Y-shaped band placed in front of the ankle-joint

The inferior extensor retinaculum of the foot is a Y-shaped band placed in front of the ankle-joint, the stem of the Y being attached laterally to the upper surface of the calcaneus, in front of the depression for the interosseous talocalcaneal ligament; it is directed medialward as a double layer, one lamina passing in front of, and the other behind, the tendons of the peroneus tertius and extensor digitorum longus.

The anterior medial malleolar artery is an artery in the ankle. It arises about 5 cm. above the ankle-joint from the anterior tibial artery.

Anterior tibial recurrent artery

The anterior tibial recurrent artery is a small artery in the leg. It arises from the anterior tibial artery, as soon as that vessel has passed through the interosseous space. It ascends in the tibialis anterior muscle, ramifies on the front and sides of the knee-joint, and assists in the formation of the patellar plexus by anastomosing with the genicular branches of the popliteal, and with the highest genicular artery.

The flexor retinaculum of foot is a strong fibrous band, extending from the bony ankle prominence (malleolus) above, to the margin of the heelbone (calcaneus) below, converting a series of bony grooves in this situation into canals for the passage of the tendons of the flexor muscles and the posterior tibial vessels and tibial nerve into the sole of the foot.

Interosseous membrane of leg

The interosseous membrane of the leg extends between the interosseous crests of the tibia and fibula, helps stabilize the Tib-Fib relationship and separates the muscles on the front from those on the back of the leg.

Superior extensor retinaculum of foot Upper part of the extensor retinaculum of foot

The superior extensor retinaculum of the foot is the upper part of the extensor retinaculum of foot which extends from the ankle to the heelbone.

Tarsal tunnel Canal in the ankle area

The tarsal tunnel is found along the inner leg posterior to the medial malleolus.

Anterior compartment of leg Part of the Fascial compartments of leg

The anterior compartment of the leg is a fascial compartment of the lower limb. It contains muscles that produce dorsiflexion and participate in inversion and eversion of the foot, as well as vascular and nervous elements including the anterior tibial artery and veins, and the deep fibular nerve.

Fibular artery

In anatomy, the fibular artery, also known as the peroneal artery, supplies blood to the lateral compartment of the leg. It arises from the tibial-fibular trunk.
