The lateral compartment of the leg is a fascial compartment of the lower

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 ...

. It contains muscles which make eversion and plantarflexion of the foot.

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 ...

Action

* Foot evertors * Foot plantarflexion

Nerve Supply

The lateral compartment of the leg is supplied by the

superficial fibular nerve The superficial fibular nerve (also known as superficial peroneal nerve) innervates the fibularis longus and fibularis brevis muscles and the skin over the antero-lateral aspect of the leg along with the greater part of the dorsum of the foot (wit ...

(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. Structure Course The anterior tibial artery is a branch of the poplitea ...

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 int ...
