Muscle of the human body located in the lower limb
In human anatomy, the fibularis tertius (also known as the peroneus tertius ) is a muscle in the anterior compartment of the leg . It acts to tilt the sole of the foot away from the midline of the body (eversion ) and to pull the foot upward toward the body (dorsiflexion ).
Structure
[ edit ]
The fibularis tertius arises from the lower third of the front surface of the fibula , the lower part of the interosseous membrane , and septum , or connective tissue, between it and the fibularis brevis .[1]
The muscle passes downward and ends in a tendon that passes under the superior extensor retinaculum and the inferior extensor retinaculum of the foot in the same canal as the extensor digitorum longus muscle .[1] [1] metatarsal bone .[1]
The fibularis tertius is supplied by the deep fibular nerve .[2] [3] common fibular nerve .[2] fibularis muscles , which are located in the lateral compartment of the leg and are supplied by the superficial fibular nerve , since the fibularis tertius is found in the anterior compartment of the leg.
The fibularis tertius may be absent in humans .[1] [4] [4] [1] primates , which is one reason its function has been linked to efficient bipedalism .[4]
Function
[ edit ]
As a weak dorsiflexor of the ankle joint, the fibularis tertius assists in pulling the foot upward toward the body. It also assists in tilting the sole of the foot away from midline of the body at the ankle (eversion ). It is likely to be helpful though not essential in bipedal walking .[4]
Clinical significance
[ edit ]
The fibularis tertius may be involved in ankle injuries[1] [5] hyperextension .[6]
The fibularis tertius may be imaged using medical ultrasound .[6]
Nomenclature and etymology
[ edit ]
Terminologia Anatomica [7]
The word "peroneus" comes from the Greek word "perone," meaning pin of a brooch or a buckle. In medical terminology, the word refers to being of or relating to the fibula or to the outer portion of the leg.
Other animals
[ edit ]
The fibularis tertius muscle in horses originates from the near the lateral condyle of the femur , passes through the extensor sulcus on the head of the tibia , and inserts onto the third metatarsal bone , the third and fourth tarsal bones , and the calcaneus .[8] Achilles tendon to have a slight dip.[8]
