What is true about adductors of thigh?
High-Yield Explanation
The adductor muscles are disposed in 3 layers. the anterior layer consists of pectineus and adductor longue.Middle layer is adductor brevis. Posterior layer is adductor Magnus.Adductor Magnus is a fan-shaped muscle. The anterior fibres are horizontal, middle fibres are oblique and the posterior fibres are nearly veical. It arises from ischiopubic ramus and the lower pa of ischial tuberosity. It has a long inseion, posterior to the other adductor muscles, to the back of the femur from medial side of gluteal tuberosity to the adductor tubercle.The ischial pa of adductor Magnus acts with hamstring muscles to extend the hip joint.The main aeries and on the adductor compament of the thigh are obturator aery and medial circumflex femoral aery. The profunda aery descends posterior to adductor longus,close to the femur. Medial circumflex aery passes backwards between pectineus and adductor muscles inferiorly, and the psoas, obturator externus and quadratus femoris muscles superiorly. Obturator aery accompanies obturator nerve through obturator canal and divides into anterior and posterior branches which form aerial circle on obturator membrane deep to obturator externus.Ref: Cunningham&;s manual of practical anatomy (14th edition) pg:115-119.
