Latin muscle parts
Crural muscle – anterior compartment
The English name for this muscle is the third muscle of the pointed bone. The word peroneus is from the Greek perone meaning “anything sharp or pointed.” This was an alternate term for the fibula, which is a Latin word designating a “buckle or brooch.” It arises from the Latin word figo meaning “to fasten.” In some animals the bone is short and pointed at its distal end where it abuts the tibia. This appearance resembled a needle to its brooch.Tertius is the Latin term meaning “third.”
Medial surface of the distal third of the fibula and the adjacent interosseous membrane (fibers blend with the extensor digitorum longus).
Medial side of the dorsal surface of the base of 5th metatarsal and down onto the shaft of this bone.
Dorsal flexion of the ankle joint; eversion of the foot
Deep peroneal nerve (L5 and S1)
The muscle receives branches from the anterior tibial artery, anterior lateral malleolar artery, perforating branch of the peroneal artery, a branch from the arcuate artery, and the fourth dorsal metacarpal artery.
