Which muscle bounds the femoral region laterally?

The sartorius muscle is the muscle that bounds the femoral region laterally. It runs diagonally across the thigh from the anterior superior iliac spine to the medial aspect of the tibia. This specific positioning allows the sartorius to play a significant role in the movement of the hip and knee by flexing the thigh and leg.

Because of its location, the sartorius creates a lateral border for the femoral triangle, which is clinically significant. This triangle contains important structures such as the femoral nerve, artery, and vein. Additionally, understanding the anatomy and boundaries of the femoral region is crucial for surgical procedures, nerve blocks, and the assessment of traumatic injuries.

While other muscles listed also have significant roles in the anatomy of the thigh, their positions do not define the lateral boundary of the femoral region.
