El músculo abductor del dedo gordo del pie es un músculo intrínseco del pie. Se encuentra dentro de la primera capa muscular plantar (la más superficial) del pie. Inserciones: se origina en el tubérculo medial del calcáneo, el retináculo flexor y la aponeurosis plantar. Se inserta en la base medial de la falange proximal del dedo gordo del pie. Acciones: abducción y flexión del dedo gordo del pie. Inervación: nervio plantar medial (rama del nervio tibial). Irrigación sanguínea: arteria plantar medial y arteria plantar metatarsiana.

Learn More Frequent questions What is the abductor hallucis muscle? The abductor hallucis muscle is an intrinsic muscle of the foot located in the superficial layer of the plantar muscles. It plays a crucial role in the abduction and flexion of the big toe. Where does the abductor hallucis muscle originate? The abductor hallucis muscle originates from the medial tubercle of the calcaneus, the flexor retinaculum, and the plantar aponeurosis. These attachments provide stability and support for its function. What is the primary function of the abductor hallucis muscle? The primary function of the abductor hallucis muscle is to abduct and flex the big toe. This action is essential for maintaining balance and proper foot mechanics during walking. Which nerve innervates the abductor hallucis muscle? The abductor hallucis muscle is innervated by the medial plantar nerve, which is a branch of the tibial nerve. This innervation is vital for the muscle's movement and coordination. What is the blood supply to the abductor hallucis muscle? The blood supply to the abductor hallucis muscle comes from the medial plantar artery and the plantar metatarsal artery. Adequate blood flow is important for muscle function and overall foot health.
