Sartorius muscle Sartorius muscle The sartorius muscle () is the longest muscle in the human body. It is a long, thin, superficial muscle that runs down the length of the thigh in the anterior compartment. The sartorius muscle originates from the anterior superior iliac spine and part of the notch between the anterior superior iliac spine and anterior inferior iliac spine. It runs obliquely across the upper and anterior part of the thigh in an inferomedial direction. It passes behind the medial condyle of the femur to end in a tendon. This tendon curves anteriorly to join the tendons of the gracilis
Deep artery of the thigh Deep artery of the thigh The deep artery of the thigh, (profunda femoris artery or deep femoral artery) is a branch of the femoral artery that, as its name suggests, travels more deeply (posteriorly) than the rest of the femoral artery. The deep artery of the thigh branches off the femoral artery soon after its origin. It travels down the thigh closer to the femur than the femoral artery, running between the pectineus and the adductor longus, and running on the posterior side of adductor longus. The deep femoral artery does not leave the thigh. The deep artery of the
