What muscle is responsible for dorsiflexion of the toes and metatarsophalangeal joints?

The muscle that is responsible for dorsiflexion of the toes and metatarsophalangeal joints is the Extensor Digitorum Longus. This muscle is primarily involved in extending the toes and plays a crucial role in lifting the toes upwards (dorsiflexion) during movement, particularly when the foot is in a position for taking steps or walking. It originates from the lateral condyle of the tibia and the anterior surface of the fibula, allowing it to extend to the four lesser toes effectively.

Understanding the function of the Extensor Digitorum Longus is essential since it plays a significant role in balance and gait. Proper dorsiflexion is crucial for the foot to clear the ground during walking and running, preventing dragging of the toes and helping maintain an effective and efficient walking pattern. The other muscles listed have different primary functions—Flexor Hallucis Longus and Flexor Digitorum Longus are primarily responsible for plantarflexion, or flexing the toes downward, rather than assisting with dorsiflexion. Additionally, Extensor Hallucis Longus mainly extends and dorsiflexes the big toe, but does not provide the same level of function for the lesser toes as Extensor Dig
