Latin muscle parts
Crural muscle – lateral compartment
The English name for this muscle is the long 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.Longus is the Latin term meaning “long.” This is being used as a comparative reference to a shorter muscle that does the same thing.
Lateral surface of the head and the proximal 2/3rds of the fibula.
Lateral side of the base of the first metatarsal bone, lateral side of the base of the medial cuneiform, and the inferior base of the second metatarsal bone
Plantar flexion of the ankle joint; eversion of the foot; helps maintain the longitudinal and transverse arches of the foot.
Superficial peroneal nerve (L5 and S1)
From proximal to distal, the belly of the muscle is supplied by the inferior lateral genicular artery, the anterior tibial artery, anterior tibial recurrent artery, posterior tibial recurrent artery, circumflex fibular artery, muscular branches from the fibular (peroneal) artery. The tendon is supplied by the anterior lateral malleolar artery, lateral calcaneal artery, lateral tarsal artery, lateral plantar artery, and the medial plantar artery.
