Fibularis brevis

Fibularis brevis is a muscle of the human body, specifically located in the lateral part of the leg. It is one of the muscles involved in the movement of the foot and ankle. The fibularis brevis muscle is innervated by the superficial fibular nerve and receives its blood supply from the fibular artery.

Anatomy

The fibularis brevis muscle originates from the lower two-thirds of the fibula, a bone located on the lateral side of the tibia. It runs down the leg and inserts into the base of the fifth metatarsal, one of the long bones in the foot. The muscle is located deep to the fibularis longus muscle and is covered by the fibularis longus tendon as it curves around the lateral malleolus.

Function

The primary function of the fibularis brevis muscle is to evert the foot, which means to turn the sole of the foot outward. It also assists in plantarflexion of the foot, or pointing the toes downward. This muscle plays a crucial role in walking, running, and jumping.

Clinical Significance

Injury to the fibularis brevis muscle can result in foot and ankle pain, as well as difficulty in performing movements that involve eversion and plantarflexion of the foot. Treatment typically involves rest, physical therapy, and in some cases, surgery.
