20 Ιουλ 2023 · The fibularis longus muscle is innervated by the superficial fibular nerve (L5, S1). The main function of this muscle is to produce the plantarflexion and eversion of the foot on the ankle joint. In this article, we will discuss the anatomy and function of the muscle, as well as its clinical relevance.
The fibularis longus muscle is involved in multiple actions: - everts the foot at the subtalar and transverse tarsal joints; - assists in plantarflexion of the foot at the ankle joint;
16 Ιαν 2023 · The fibularis longus is a muscle in the lateral compartment of the leg.. It is the larger muscle in this compartment and is located superficial to the fibularis brevis. Attachments. The fibularis longus originates from the superior and lateral surface of the fibula and the lateral tibial condyle.
Anatomy & Physiology: Muscles—Fibularis (Peroneus) Longus . STRUCTURE. • Origin: fibular head and body; lateral condyle of tibia. • Insertion: metatarsal I and first cuneiform. FUNCTION. • Concentric action: plantar flexion; eversion. • Reverse mover action: evert talus at subtalar joint; plantar flexion.
3 Νοε 2023 · The fibularis longus muscle is innervated by the superficial fibular (peroneal) nerve (L5, S1), a branch of the common fibular nerve. The function of the fibularis longus muscle is to plantar flex and evert the foot. It also provides support to both the longitudinal and transverse arches of the foot.
The fibularis longus muscle plays several critical roles in the movement and stability of the foot and ankle. Here are its primary functions: Eversion of the Foot: The primary function of the fibularis longus is to evert the foot. Eversion is the movement of turning the sole of the foot outward.
In human anatomy, the fibularis longus (also known as peroneus longus) is a superficial muscle in the lateral compartment of the leg. It acts to tilt the sole of the foot away from the midline of the body (eversion) and to extend the foot downward away from the body (plantar flexion) at the ankle.
