The fibularis brevis is a muscle in the lateral compartment of the leg. It is located deep to the fibularis longus. Attachments: Originates from the inferolateral surface of the fibular shaft. The muscle belly forms a tendon, which descends with the fibularis longus into the foot. It travels posteriorly to the lateral malleolus, passing over the calcaneus and the cuboidal bones. The tendon then attaches to a tubercle on the 5th metatarsal. Actions: Eversion of the foot. Innervation: Superficial fibular (peroneal) nerve. Blood supply: Fibular artery.
