Tibialis Anterior
0% read · 1 min left
The shin muscle that dorsiflexes the foot (lifts the top of the foot toward the shin) — the antagonist to the calf muscles.
Detail
The tibialis anterior lies along the front of the lower leg, lateral to the tibia (shin bone). Its primary action is dorsiflexion — drawing the top of the foot upward toward the anterior tibia — and it assists in inversion of the foot. It is the functional antagonist of the gastrocnemius and soleus, which produce plantar flexion.
The source names the tibialis anterior on the anterior muscle diagram and references it in the movement-terminology and range-of-motion material (dorsiflexion of the foot ≈ 10–15°).
Key facts
- Action: dorsiflexion of the foot; assists inversion.
- Antagonist to the calf muscles (gastrocnemius, soleus).
- Dorsiflexion ROM at the ankle: approximately 10–15°.
Connections
- dorsiflexion — the movement it produces.
- gastrocnemius, soleus — antagonists (plantar flexion).
- foot-ankle-rom — range-of-motion values for the ankle.
