The fibularis brevis muscle (or peroneus brevis in British English) lies under cover of the fibularis longus, and is a shorter and smaller muscle.

Structure

It arises from the lower two-thirds of the lateral surface of the body of the fibula; medial to the fibularis longus; and from the intermuscular septa separating it from the adjacent muscles on the front and back of the leg.

The fibers pass vertically downward, and end in a tendon which runs behind the lateral malleolus along with but in front of that of the preceding muscle, the two tendons being enclosed in the same compartment, and lubricated by a common mucous sheath.

It then runs forward on the lateral side of the calcaneus, above the trochlear process and the tendon of the Peronæus longus, and is inserted into the tuberosity at the base of the fifth metatarsal bone, on its lateral side.

Innervation

It is also innervated by the superficial fibular (peroneal) nerve.

Function

The muscle assists in weak plantarflexion and eversion of the foot.

History

Etymology

The terms "Peroneal" (i.e., Artery, Retinaculum) and "Peroneus" (i.e., Longus and Brevis) are derived from the Greek word Perone (pronounced Pair-uh-knee) meaning pin of a brooch or a buckle. In medical terminology, both terms refer to being of or relating to the fibula or to the outer portion of the leg.

INTRODUCTION: Physical and rehabilitation medicine physicians commonly see patients with chronic functional ankle instability. The main anatomical structures involved in ankle stability are the peroneus (fibularis) brevis and peroneus longus muscles. Several anatomical muscle-tendon variations have

BACKGROUND: Myostatin (GDF-8) is known as a potent inhibitor of muscle growth and development, and myostatin is also expressed early in the fracture healing process. The purpose of this study was to test the hypothesis that a new myostatin inhibitor, a recombinant myostatin propeptide, can enhance t
