Latin name

Musculus tibialis anterior

Group

Crural muscle – anterior compartment

Etymology

The English name for this muscle is the muscle before the shinbone. The word tibialis comes from the Latin word tibia meaning the “shinbone, or flute.” It was probably originally named for the shinbone and later took on the meaning of flute, because people made flutes from the tibiae of animal bones. The Latin term anterior is derived from the Latin ante meaning “before.”

Origin

Lateral condyle, proximal half of the shaft of the tibia, and the adjacent interosseous membrane.

Insertion

Medial and inferior surfaces of the medial cuneiform and the base of the first metatarsal bone.

Action

Dorsal flexion of the ankle joint (tibiotalar); inversion of the foot

Nerve supply

Deep peroneal nerve (L4 and L5)

Blood supply

The muscle belly receives branches from the anterior tibial artery and anterior tibial recurrent artery. From proximal to distal, the tendon receives branches from the anterior medial malleolar artery, dorsalis pedis artery, medial tarsal arteries, posterior tibial artery, and medial malleolar and calcaneal arteries.

Latin

Musculus tibialis anterior

French

Muscle tibial antérieur
