What are the two key muscles that contribute to foot eversion?

1. Flexor Digitorum and Extensor Digitorum

2. Gastrocnemius and Soleus

3. Peroneus Longus and Peroneus Brevis

4. Anterior Tibialis and Posterior Tibialis

The correct answer is: Peroneus Longus and Peroneus Brevis

The two key muscles that contribute to foot eversion are the Peroneus Longus and Peroneus Brevis. These muscles are located on the lateral side of the lower leg and play a crucial role in the movement of the foot. Specifically, they help to tilt the foot away from the midline of the body, a movement known as eversion. The Peroneus Longus originates from the upper part of the fibula and extends down to the base of the first metatarsal and medial cuneiform bone, while the Peroneus Brevis also originates from the fibula but attaches to the base of the fifth metatarsal. Their coordinated action not only facilitates eversion but also provides stability to the foot and aids in various activities like walking, running, and changing directions. Other choices involve muscles that do not primarily function in eversion. For instance, the muscles listed in the other options play different roles such as flexion, extension, or inversion, which are not directly associated with the eversion of the foot. Understanding the specific functions of these muscles helps clarify their significance in movements and athletic performance.
