This compartment consists of 2 muscles
Peroneus longus
Origin: head of fibula, upper half of fibula, lateral condyle of tibia and interosseous
Insertion: base of 1 metatarsal and medial cuneiforms
Action: plantar flexion and eversion of the foot
Innervation: superficial fibular (peroneus)nerve L4-S1
*this muscle originates lateral side and inserts into medial side
* When this muscle gets tight, it causes the flat feet and the less foot arch
Peroneus brevis
Origin: Lateral distal 2/3 of the fibula and intermuscular septum
Insertion: Fifth metatarsal
Action: Plantar flexion and eversion of the foot
Innervation: superficial fibular (peroneus)nerve L4-S1
Superficial fibular nerve
*Innervates the short head of the biceps femoris
*Due to the location, sensory is on the anterior and lateral skin
* If damaged or these two muscles compress this nerve, this nerve can cause some numbness in the lateral side of the lower leg
