Peroneus longus
Peroneus Longus
The Peroneus Longus (pronounced: peh-roh-nee-us lon-gus), also known as the Fibularis Longus, is a muscle in the lateral compartment of the leg.
Etymology
The term "Peroneus" is derived from the Greek word "Perone" meaning pin of a brooch or a buckle, in reference to the shape of the fibula. "Longus" is a Latin term meaning long, referring to the length of this muscle.
Anatomy
The Peroneus Longus originates from the head and upper part of the lateral surface of the fibula. It runs obliquely downwards and backwards, and inserts into the lateral side of the base of the first metatarsal and the medial cuneiform.
Function
The Peroneus Longus acts to evert and plantarflex the ankle joint. It also provides lateral stability to the ankle when the foot is on the ground.
