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.

Acknowledge Frequent questions What is the fibularis brevis muscle? The fibularis brevis is a muscle located in the lateral compartment of the leg, situated beneath the fibularis longus. It plays a crucial role in foot eversion. Where does the fibularis brevis originate? The muscle originates from the inferolateral surface of the fibular shaft. This position allows it to effectively contribute to foot movement. How does the fibularis brevis attach in the foot? The tendon of the fibularis brevis descends with the fibularis longus, travels posteriorly to the lateral malleolus, and attaches to a tubercle on the 5th metatarsal. This attachment is vital for its function in eversion. What is the primary action of the fibularis brevis? The primary action of the fibularis brevis is the eversion of the foot. This movement is essential for maintaining balance and stability during activities like walking. Which nerve innervates the fibularis brevis muscle? The fibularis brevis is innervated by the superficial fibular (peroneal) nerve. This innervation is important for the muscle's function in foot movement. Rate This Article
