The abductor hallucis muscle does which action?

Explanation:
The abductor hallucis is a muscle on the medial side of the sole that pulls the big toe away from the rest of the toes. Its tendon inserts on the proximal phalanx of the big toe, so when it contracts, the big toe moves laterally at the first metatarsophalangeal joint. This is its defining action: abducting the big toe. It does not adduct the big toe (that’s the role of adductor hallucis), nor does it primarily flex or extend the toe (those actions come from other muscles).
