Document Summary
It becomes tendinous above the knee and crosses the joint. It develops a fusiform shaped belly at its middle. Its actions are mainly flexion of knee, but also adduction of hip and medial rotation of thigh (with knee semi flexed: pectineus, this is a quadrilateral muscle situated at the upper and medial part of the thigh. Its fibres pass downward and laterally between the psoas major and adductor. Its upper attachment is the superior ramus of the pubis. It appears to consist of two layers, superficial and deep, supplied by different nerves longus. It lies anterior to semimembranosus and semitendinosus (is very deep) Its upper attachment is the ischiopubic ramus, running down toward the ischial tuberosity. The ischiopubic fibres fan out forming a large triangular muscular sheet. These fibres pass laterally and slightly backward toward the linea aspera, and may be fused with the quadratus femoris. The fibres from the ischiopubic ramus run the length of the linea aspera.
