El músculo aductor largo es un músculo del compartimento medial del muslo. Es un músculo grande y plano que cubre parcialmente el músculo aductor corto y el aductor mayor. Inserciones: se origina en el hueso púbico de la pelvis y se extiende en forma de abanico. Presenta una amplia inserción distal a lo largo de la línea áspera del fémur. Acciones: aducción del muslo. Inervación: nervio obturador (L2-L4). Irrigación sanguínea: arteria obturadora. By TeachMeSeries Ltd (2026) Fig. 1: músculos de la cara medial del muslo. Se han eliminado los músculos superpuestos del compartimento anterior. By TeachMeSeries Ltd (2026) Fig. 2: corte transversal de la parte inferior del muslo, en el que se observan algunos de los músculos mediales del muslo. El músculo aductor corto y el obturador externo se insertan en la parte superior del muslo, por lo que no están visibles en este corte transversal.

Learn More Frequent questions What is the adductor longus muscle? The adductor longus muscle is a large, flat muscle located in the medial compartment of the thigh. It primarily facilitates the adduction of the thigh. Where does the adductor longus muscle originate and insert? This muscle originates from the pubic bone of the pelvis and has a broad distal insertion along the linea aspera of the femur. Its fan-like shape allows it to cover parts of the adductor brevis and adductor magnus muscles. What is the primary function of the adductor longus muscle? The main function of the adductor longus muscle is to adduct the thigh. This action is crucial for stabilising the pelvis during activities such as walking and running. Which nerve innervates the adductor longus muscle? The adductor longus muscle is innervated by the obturator nerve, specifically the fibres from the L2 to L4 spinal segments. This innervation is essential for its motor function. What is the blood supply to the adductor longus muscle? The adductor longus muscle receives its blood supply from the obturator artery. This vascularisation is important for maintaining its function and health. Rate This Article
