El músculo aductor del dedo gordo es un músculo intrínseco del pie. Se encuentra en la tercera capa muscular plantar del pie y tiene dos cabezas: la oblicua y la transversal. Inserciones: Cabeza oblicua: se origina en la base de los metatarsianos segundo, tercero y cuarto. Cabeza transversal: se origina en los ligamentos plantares de las articulaciones metatarsofalángicas. Ambas cabezas se insertan en la cara externa de la base de la falange proximal del dedo gordo del pie. Acciones: aducción del dedo gordo del pie. Sujeta el arco transversal del pie. Inervación: rama profunda del nervio plantar lateral. Irrigación sanguínea: arteria plantar medial. By TeachMeSeries Ltd (2026) Fig. 4: la tercera capa de músculos plantares.

Learn More Frequent questions What is the role of the adductor hallucis muscle in the foot? The adductor hallucis muscle is responsible for the adduction of the big toe and helps support the transverse arch of the foot. It consists of two heads, the oblique and the transverse, which work together to perform these functions. Where does the adductor hallucis muscle originate? The adductor hallucis muscle has two heads: the oblique head originates from the bases of the second, third, and fourth metatarsals, while the transverse head arises from the plantar ligaments of the metatarsophalangeal joints. Both heads converge to insert on the proximal phalanx of the big toe. What is the innervation of the adductor hallucis muscle? The adductor hallucis muscle is innervated by the deep branch of the lateral plantar nerve. This nerve supplies the muscle with the necessary signals for movement and function. How does the adductor hallucis contribute to foot stability? The adductor hallucis aids in stabilising the foot by supporting the transverse arch during weight-bearing activities. Its action of adducting the big toe also enhances balance and stability when standing or walking. What is the blood supply to the adductor hallucis muscle? The adductor hallucis muscle receives its blood supply primarily from the medial plantar artery. This vascularisation is crucial for maintaining the muscle's function and health. Rate This Article
