Neurovascular bundle of anterior compartment of leg passes between the tendons of
**Core Concept**
The neurovascular bundle of the anterior compartment of the leg consists of the deep peroneal nerve and the anterior tibial vessels. This bundle is responsible for supplying the muscles of the anterior compartment, which are primarily responsible for dorsiflexion and toe extension. The precise location of the neurovascular bundle is critical for surgeons and clinicians to avoid injury during procedures in the leg.
**Why the Correct Answer is Right**
The neurovascular bundle passes between the tendons of the extensor hallucis longus and the extensor digitorum longus muscles in the anterior compartment of the leg. This is a result of the anatomical arrangement of these muscles and their tendons, which provides a safe passage for the neurovascular bundle. The deep peroneal nerve and the anterior tibial vessels are closely associated with these muscles and their tendons, and they run between them to supply the muscles of the anterior compartment.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the neurovascular bundle does not pass between the tendons of the tibialis anterior and the peroneus tertius muscles. While these muscles are also present in the anterior compartment, the neurovascular bundle is specifically associated with the extensor hallucis longus and extensor digitorum longus muscles.
**Option B:** This option is incorrect because the neurovascular bundle does not pass between the tendons of the peroneus longus and the peroneus brevis muscles. These muscles are present in the lateral compartment of the leg, which is a different compartment from the anterior compartment.
**Clinical Pearl / High-Yield Fact**
The neurovascular bundle of the anterior compartment of the leg is at risk during procedures such as ankle arthroscopy or when performing a peroneal nerve block. Surgeons and clinicians must be aware of the precise location of this bundle to avoid injury and ensure successful outcomes.
**Correct Answer:** C. The neurovascular bundle of the anterior compartment of the leg passes between the tendons of the extensor hallucis longus and the extensor digitorum longus muscles.
