It can be classified in the medial compartment of thigh[1] (when the function is emphasized) or the anterior compartment of thigh (when the nerve is emphasized). The medial fascial compartment of thigh contains the hip adductors. The anterior fascial compartment of thigh contains the Knee Extensors and Hip Flexors. [2]

Action
It is one of the muscles primarily responsible for hip flexion. It also adducts and medially rotates the thigh.
Innervation
Innervation is by the femoral nerve (L2 and L3) and occasionally a branch of the obturator nerve. The femoral nerve, the largest branch of the Lumbar plexus, arises from the dorsal divisions of the second third and fourth Lumbar nerves. The obturator nerve arises from the ventral divisions of the second third and fourth Lumbar nerves; the branch from the third is the largest while that from the second is
Origin and insertion
It arises from the pectineal line of the pubis and to a slight extent from the surface of bone in front of it, between the iliopectineal eminence and tubercle of the pubis, and from the fascia covering the anterior surface of the muscle; the fibers pass downward, backward, and lateralward, to be inserted into a the pectineal line of the femur which leads from the lesser trochanter to the linea aspera. The pecten pubis or pectineal line of the pubis is a ridge on the superior ramus of the Pubic bone. For the bone in many mammals often called the penis bone see Baculum The android pubic bone is the Ventral and Anterior Medial to the Anterior inferior iliac spine is a broad shallow groove over which the Iliacus and Psoas major pass On the posterior surface of the Femur, the intermediate ridge or pectineal line is continued to the base of the Lesser trochanter and gives attachment to the The lesser trochanter (small trochanter of the Femur is a conical eminence which varies in size in different subjects It projects from the lower and back part of the base The linea aspera is a ridge of roughened surface on the posterior aspect of the Femur, to which are attached Muscles and intermuscular Septa.
