El músculo aductor mayor es un músculo del compartimento medial del muslo . Es el músculo más grande dentro de este compartimento y está compuesto por dos partes: un componente aductor y un componente isquiotibial. Inserciones Aductor: se origina en las ramas inferiores del pubis y las ramas del isquion, y se inserta en la línea áspera del fémur. Parte isquiotibial: se origina en la tuberosidad isquiática y se inserta en el tubérculo aductor y la línea supracondílea medial del fémur. Acciones: Aductor: aducción y flexión del muslo. Isquiotibiales: aducción y extensión del muslo. Inervación: Aductor: nervio obturador (L2-L4). Parte isquiotibial: componente tibial del nervio ciático (L4-S3). Irrigación sanguínea: arteria obturadora, arteria femoral profunda y arteria femoral circunfleja medial. 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 primary function of the adductor magnus muscle? The adductor magnus muscle primarily facilitates the adduction and flexion of the thigh. Its ischiotibial component also aids in thigh extension. Where does the adductor magnus muscle originate and insert? The adductor magnus originates from the inferior pubic ramus and ischial ramus, inserting along the linea aspera of the femur. Its ischiotibial part originates from the ischial tuberosity, inserting at the adductor tubercle and medial supracondylar line of the femur. What nerves innervate the adductor magnus muscle? The adductor magnus is innervated by the obturator nerve for its adductor portion and the tibial component of the sciatic nerve for its ischiotibial part. This dual innervation reflects its distinct functional roles. Which arteries supply blood to the adductor magnus muscle? The adductor magnus receives blood supply from the obturator artery, deep femoral artery, and medial femoral circumflex artery. This vascularisation is crucial for its metabolic needs during movement. What clinical significance does the adductor magnus muscle hold? The adductor magnus is important for stabilising the hip and facilitating movements such as walking and running. Its injury can lead to difficulties in thigh movement and hip stability.
