Which muscle extends the joints of the toes 2-5?

Explanation:
Extending the joints of the toes 2–5 is carried out by the extensor digitorum longus. This muscle runs along the front of the leg and sends tendons to toes 2–5, pulling the toe joints (metatarsophalangeal and interphalangeal joints) upward to straighten the toes. It also helps with dorsiflexion of the foot at the ankle. The other muscles listed don’t extend the toes: gastrocnemius and soleus primarily plantarflex the ankle, and vastus lateralis extends the knee.
