The anterior tibialis muscle test evaluates the ________________ nerve.
Superficial Fibular
Deep Fibular
Tibial
Gluteal
The correct answer is: Deep Fibular
The anterior tibialis muscle test is specifically designed to evaluate the function of the deep fibular nerve. This nerve is responsible for innervating the anterior compartment of the leg, which includes the anterior tibialis muscle. The anterior tibialis plays a crucial role in dorsiflexion of the ankle, meaning it helps lift the foot upward. Testing this muscle can effectively assess the integrity and functionality of the deep fibular nerve. In contrast, the superficial fibular nerve primarily innervates the lateral compartment of the leg and is involved in eversion of the foot. The tibial nerve innervates the posterior compartment of the leg and is responsible for plantarflexion. The gluteal nerves are associated with the muscles of the hip, which is not relevant in the context of the anterior tibialis muscle. Thus, the correct choice is indeed the deep fibular nerve, as it directly correlates with the muscle's function being tested.
