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

Origin and insertion

It arises from the lower two-thirds of the lateral surface of the body of the fibula; medial to the Peronæus 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.

Terminology

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.

ankle joint is formed where the foot and the leg meet. The ankle, or talocrural joint, is a synovial hinge joint that connects the distal ends of the tibia and fibula in the lower limb with the proximal end of the talus bone in the foot.

subtalar joint, also known as the talocalcaneal joint, is a joint of the foot. It occurs at the meeting point of the talus and the calcaneus. The joint allows inversion and eversion of the foot, but plays no role in dorsiflexion or plantarflexion of the foot.

Plantarflexion is the movement which increases the angle between the foot and the leg, as when depressing an automobile pedal. The word "Plantar" translates as "toward the sole" ("Planta").
