El músculo flexor corto del dedo gordo es un músculo intrínseco del pie. Se localiza dentro de la tercera capa muscular plantar del pie y tiene dos cabezas de origen. Inserciones: Cabeza lateral: se origina en las superficies plantares del cuboides y los cuneiformes laterales. Cabeza medial: se origina en el tendón del tibial posterior. Las fibras convergen en un único vientre muscular, que se inserta en la base de la falange proximal del dedo gordo. Acciones: flexión del dedo gordo en la articulación metatarsofalángica. Inervación: nervio plantar medial. Irrigación sanguínea: arterias tibial posterior y peronea. By TeachMeSeries Ltd (2026) Fig. 4: la tercera capa de músculos plantares.

Learn More Frequent questions What is the function of the flexor hallucis brevis muscle? The flexor hallucis brevis muscle primarily facilitates the flexion of the big toe at the metatarsophalangeal joint. This action is crucial for activities such as walking and maintaining balance. Where does the flexor hallucis brevis muscle originate? This muscle has two heads of origin: the lateral head arises from the plantar surfaces of the cuboid and lateral cuneiform bones, while the medial head originates from the tendon of the posterior tibial muscle. What are the insertion points of the flexor hallucis brevis? The muscle inserts at the base of the proximal phalanx of the big toe, where it contributes to the flexion of the toe. Which nerve innervates the flexor hallucis brevis muscle? The flexor hallucis brevis is innervated by the medial plantar nerve, which is responsible for providing motor function to this muscle. What is the blood supply for the flexor hallucis brevis? The blood supply to the flexor hallucis brevis comes from the posterior tibial artery and the peroneal artery, ensuring adequate oxygenation and nutrients for its function. Valora este artículo
