Verified step by step guidance

Understand the term 'dorsiflexion': Dorsiflexion refers to the movement that decreases the angle between the dorsum (top) of the foot and the leg, essentially pulling the toes upward toward the shin.

Identify the muscles responsible for dorsiflexion: The primary muscles involved in dorsiflexion are located in the anterior compartment of the leg, such as the tibialis anterior, extensor digitorum longus, and extensor hallucis longus.

Analyze the anatomical location of the anterior compartment of the leg: The anterior compartment is located at the front of the lower leg, between the tibia and fibula, and contains muscles that are responsible for dorsiflexion.

Evaluate the other options provided: The lateral compartment of the leg contains muscles responsible for eversion of the foot, the posterior compartment of the thigh contains muscles involved in knee flexion and hip extension, and the plantar surface of the foot contains muscles involved in toe flexion and arch support.

Conclude that the correct answer is the anterior compartment of the leg, as it houses the muscles responsible for dorsiflexion of the foot.
