Which three muscles attach at the fibular head?

The three muscles that attach at the fibular head are indeed the biceps femoris, peroneus longus, and soleus.

The biceps femoris, which is one of the hamstring muscles, originates from the ischial tuberosity and the fibula and plays a critical role in knee flexion and hip extension. The fibular head serves as an important site for the attachment of this muscle, facilitating its function.

Peroneus longus (also known as fibularis longus) also attaches at the fibular head, helping in the eversion of the foot and stabilizing the ankle. This muscle travels down the lateral aspect of the leg, making its attachment at the fibular head essential for its mechanical advantage during movement.

Lastly, the soleus, a powerful muscle in the calf that contributes to plantarflexion of the ankle, has its origin near the fibular head. This position is important for producing force during walking and running.

Together, these attachments highlight the role of the fibular head in linking these muscles to support lower limb movement and stability. Other choices listed do not accurately include the correct combination of muscles associated with the fibular head.
