Document Summary

Psoas major is longer and thicker, more medial: origin lumbar vertebrae, ventral rami nerve innervation insertion femur. Prime mover of thigh flexion, flexing trunk on the thigh, flexes the vertebral column laterally and very important for maintaining posture. Sartorius straplike superficial muscle, running obliquely from the thigh to the knee longest muscle in the body, crosses the hip and knee joints. Weak knee flexor, produces a cross legged position insertion medial tibia flexes, abducts and laterally rotates the thigh femoral nerve innervation. Adductors there are 3 types: magnus, longus and brevis. All three parts adduct, flex and medially rotate the thigh (ex. riding a horse, insertion is the femur walking), pulled groin. Adducts, flexes and medially rotates the thigh insertion lesser trochanter of the femur. Gracilis long and thin superficial muscle of the medial thigh. Origin is the inferior ramus and body of the pubis and ischial ramus.
