El músculo extensor largo de los dedos es un músculo situado en el compartimento anterior de la pierna. Se encuentra situado lateralmente al músculo tibial anterior, y sus cuatro tendones se pueden palpar en la superficie dorsal del pie. Inserciones: se origina en el cóndilo lateral de la tibia y en la superficie medial del peroné. Las fibras convergen en un tendón, que discurre por la superficie dorsal del pie. El tendón se divide en cuatro y cada uno de ellos se inserta en un dedo del pie, tal y como se muestra en la imagen siguiente. Acciones: extensión de los cuatro dedos laterales y dorsiflexión del pie. Inervación: nervio peroneo profundo Irrigación sanguínea: arteria tibial anterior.

Learn More Frequent questions What is the location of the extensor digitorum longus muscle? The extensor digitorum longus muscle is located in the anterior compartment of the leg, positioned laterally to the tibialis anterior muscle. Its tendons can be felt on the dorsal surface of the foot. What are the attachments of the extensor digitorum longus muscle? This muscle originates from the lateral condyle of the tibia and the medial surface of the fibula. Its fibres converge into a single tendon that splits into four tendons, each attaching to a toe. What actions does the extensor digitorum longus muscle perform? The primary actions of the extensor digitorum longus muscle include the extension of the four lateral toes and dorsiflexion of the foot. These movements are crucial for activities such as walking and running. Which nerve innervates the extensor digitorum longus muscle? The extensor digitorum longus muscle is innervated by the deep fibular nerve. This nerve supplies the muscle to facilitate its function in toe extension and foot dorsiflexion. What is the blood supply to the extensor digitorum longus muscle? The blood supply to the extensor digitorum longus muscle comes from the anterior tibial artery. This artery ensures that the muscle receives adequate oxygen and nutrients for its activities. Rate This Article
