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
Medial compartment of thigh different innervation – namely, the femoral nerve.) Medial compartment of thigh The medial compartment of thigh is one of the fascial compartments of the thigh and contains the hip adductor muscles and the gracilis muscle. The obturator nerve is the primary nerve supplying this compartment. The muscles in the compartment are: The obturator externus muscle is sometimes considered part of this group, and sometimes excluded. (Spatially, it is in this location, but functionally, it is more similar to the other lateral rotator group muscles). The pectineus is sometimes included in this group, and sometimes excluded. (It has the same function
