El músculo flexor corto de los dedos es un músculo intrínseco del pie. Se encuentra dentro de la primera capa muscular plantar (la más superficial) del pie, entre la fascia plantar y los tendones del músculo flexor largo de los dedos. Inserciones: se origina en el tubérculo medial del calcáneo y en la aponeurosis plantar. Se inserta en las falanges medias de los cuatro dedos laterales. Acciones: flexión de los cuatro dedos laterales en las articulaciones interfalángicas proximales. Inervación: nervio plantar medial (rama del nervio tibial). Irrigación sanguínea: ramas de las arterias tibiales anterior y posterior. By TeachMeSeries Ltd (2026) Fig. 1: la primera capa de músculos plantares. Se ha seccionado la aponeurosis plantar para dejar al descubierto el músculo flexor de los dedos subyacente.

Learn More Frequent questions What is the flexor digitorum brevis muscle? The flexor digitorum brevis is an intrinsic muscle of the foot located in the superficial layer of the plantar muscles. It plays a crucial role in flexing the lateral four toes at the proximal interphalangeal joints. Where does the flexor digitorum brevis muscle originate? This muscle originates from the medial tubercle of the calcaneus and the plantar aponeurosis. Its positioning allows it to effectively engage with the tendons of the long flexor muscle. What are the attachments of the flexor digitorum brevis muscle? The flexor digitorum brevis inserts into the middle phalanges of the lateral four toes. This specific attachment facilitates its function in toe flexion. How is the flexor digitorum brevis muscle innervated? The muscle is innervated by the medial plantar nerve, a branch of the tibial nerve. This innervation is essential for its motor function in toe movement. What is the blood supply for the flexor digitorum brevis muscle? The blood supply to the flexor digitorum brevis comes from branches of the anterior and posterior tibial arteries. This vascularisation supports the muscle's metabolic needs during movement. Rate This Article
