The sartorius muscle is considered the longest muscle in the human body. It runs from the hip to the inner side of the knee. The gracilis muscle, located in the inner thigh, is one of the most slender muscles in the body.
Your thigh muscle is called your Quadricep.
butt or thigh
Your thigh is attached to lower side of trunk on one hand and to leg on other. It has strong anterior, posterior and medial muscle compartments. It can have all sort of movement with trunk on one hand and flex-ion and extension with leg on other hand. So it helps very effectively in locomotion of the human being, which does not use the forelimbs for locomotion.
Both supply to the scrotum in males, but the genitofemoral supplies to the anterior surface of the thigh while the illoinguinal nerve supplies the superior medial aspect of thigh.
