The lateral compartment of the leg is a
fascial compartment
A fascial compartment is a section within the body that contains muscles and nerves and is surrounded by deep fascia. In the human body, the limbs can each be divided into two segments – the upper limb can be divided into the arm and the forea ...

leg
A leg is a weight-bearing and locomotive anatomical structure, usually having a columnar shape. During locomotion, legs function as "extensible struts". The combination of movements at all joints can be modeled as a single, linear element ca ...

Muscles
The lateral compartment of the leg contains:
*
Fibularis longus
In human anatomy, the fibularis longus (also known as peroneus longus) is a superficial muscle in the lateral compartment of the leg. It acts to tilt the sole of the foot away from the midline of the body ( eversion) and to extend the foot downwar ...

Fibularis brevis
In human anatomy, the fibularis brevis (or peroneus brevis) is a muscle that lies underneath the fibularis longus within the lateral compartment of the leg. It acts to tilt the sole of the foot away from the midline of the body (eversion) and to e ...

Nerve Supply
The lateral compartment of the leg is supplied by the
superficial fibular nerve (superficial peroneal nerve).
Blood Supply
Its proximal and distal arterial supply consists of perforating branches of the
anterior tibial artery
The anterior tibial artery is an artery of the leg. It carries blood to the anterior compartment of the leg and dorsal surface of the foot, from the popliteal artery.

and
fibular artery
In anatomy, the fibular artery, also known as the peroneal artery, supplies blood to the lateral compartment of the leg. It arises from the tibial-fibular trunk.
Structure
The fibular artery arises from the bifurcation of tibial-fibular trunk ...
