Verified step by step guidance

Step 1: Understand the action of eversion. Eversion is the movement of the sole of the foot outward, away from the midline of the body. Muscles responsible for eversion are located on the lateral side of the leg.

Step 2: Review the function of each muscle listed. The Fibularis tertius, Fibularis brevis, and Fibularis longus are part of the lateral compartment of the leg and are known to contribute to eversion of the foot.

Step 3: Examine the Tibialis anterior. This muscle is located in the anterior compartment of the leg and primarily functions in dorsiflexion (lifting the foot upward) and inversion (turning the sole of the foot inward). It does not contribute to eversion.

Step 4: Compare the actions of the muscles. Since the Tibialis anterior is involved in inversion rather than eversion, it is the muscle that does NOT evert the foot.

Step 5: Conclude that the Tibialis anterior is the correct answer based on its anatomical location and primary function.
