El músculo extensor largo del dedo gordo del pie es un músculo situado en el compartimento anterior de la pierna. Se encuentra situado en profundidad respecto del músculo tibial anterior y del músculo extensor largo de los dedos. Su tendón emerge de entre ambos músculos para insertarse en el dedo gordo del pie. Inserciones: se origina en la superficie medial de la diáfisis del peroné. El tendón cruza de manera anterior a la articulación del tobillo y se inserta en la base de la falange distal del dedo gordo del pie. Acción: extensión del dedo gordo del pie y dorsiflexión del pie. Inervación: nervio peroneo profundo Irrigación sanguínea: arteria tibial anterior. By TeachMeSeries Ltd (2026) Fig. 1: los músculos de la parte anterior de la pierna.

Learn More Frequent questions What is the function of the extensor hallucis longus muscle? The extensor hallucis longus muscle primarily functions to extend the big toe and facilitate dorsiflexion of the foot. This action is essential for activities such as walking and running. Where does the extensor hallucis longus muscle originate? This muscle originates from the medial surface of the fibula's diaphysis. Its strategic location allows it to effectively contribute to the movement of the big toe. How does the extensor hallucis longus muscle insert into the foot? The tendon of the extensor hallucis longus muscle crosses anteriorly over the ankle joint and inserts at the base of the distal phalanx of the big toe. This insertion point is crucial for its role in toe extension. What nerves innervate the extensor hallucis longus muscle? The extensor hallucis longus muscle is innervated by the deep peroneal nerve. This nerve supply is vital for the muscle's function and coordination during movement. What is the blood supply to the extensor hallucis longus muscle? The muscle receives its blood supply from the anterior tibial artery. This vascularisation is important for maintaining the muscle's health and functionality. Rate This Article
