First, let's restate what the question is asking in our own words and lay out the options clearly so we can compare them.
Question: All of the following muscles are innervated by the deep fibular (fibular) nerve EXCEPT which one?
Answer options:
- fibularis tertius m.
- tibialis anterior m.
- fibularis longus m.
- extensor digitorum longus m.
- extensor hallucis longus m.

Option 1: fibularis tertius m. — The deep fibular nerve provides motor innervation to muscles in the anterior compartment of the leg, and fibularis tertius is traditionally supplied by the deep fibular nerve. This makes it a functionally correct example of a muscle innervated by the deep fibular nerve.

Option 2: tibialis anterior m. — The tibialis anterior is a key anterior compartment muscle and is innervated by the deep fibular nerve. This aligns with the typical innervation pattern for dorsiflexion of the foot.

Option 3: fibularis longus m. — The fibularis (peroneus) longus is located in the lateral compartment and is innervated by the superficial fibular (peroneal) nerve rather than the deep fibular nerve. This is the distinct, non-deep-fibular innervation among the provided choices.

Option 4: extensor digitorum longus m. — The extensor digitorum longus lies in the anterior compartment and receives innervation from the deep fibular nerve. This fits with the standard deep fibular innervation pattern.

Option 5: extensor hallucis longus m. — The extensor hallucis longus is also in the anterior compartment and is innervated by the deep fibular nerve, consistent with other dorsiflexors and toe extensors of the anterior group.

Now, evaluating each option for which is NOT innervated by the deep fibular nerve:
- Options 1, 2, 4, and 5 are all innervated by the deep fibular nerve, matching the typical distribution to muscles in the anterior compartment and related extensors.
- Option 3, fibularis longus, is innervated by the superficial fibular nerve, not the deep fibular nerve, and thus stands out as not following the deep fibular innervation pattern.

In summary, the reasoning hinges on the anatomical nerve supply: the deep fibular nerve covers the anterior compartment muscles (tibialis anterior, extensor digitorum longus, extensor hallucis longus, and often fibularis tertius), while the superficial fibular nerve supplies the lateral compartment muscle fibularis longus. The only exception among the listed muscles is fibularis longus, which is innervated by the superficial fibular nerve, not the deep fibular nerve.
