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 cap ...

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

Muscles

The lateral compartment of the leg contains: * Fibularis longus * Fibularis brevis

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) is a mixed (motor and sensory) nerve that provides motor innervation to the fibularis longus and fibularis brevis muscles, and sensory innervation to skin over the antero- ...

(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 popliteal ...
