tibialis anterior

Etymology: L, tibia + anticus, in front

tibialis anterior

lower-leg anterior-compartment muscle
  • origin upper segment of lateral surface of tibia and local interosseous membrane

  • insertion medial side of medial cuneiform and adjacent plantar aspect of first metatarsal base (with insertion peroneus longus tendon)

  • nerve supply deep peroneal nerve

  • action ankle dorsiflexion and subtalar joint inversion (supination) in non-weight-bearing foot; aids balance of lower leg and talus on other tarsal bones (so that leg remains vertical even when walking on uneven ground) in weight-bearing foot
