What is the lateral boundary of Scarpa's femoral triangle?

The lateral boundary of Scarpa's femoral triangle is the sartorius muscle, commonly referred to as the tailor's muscle due to its historical association with the act of tailoring. This muscle runs obliquely across the thigh from the anterior superior iliac spine to the medial side of the knee, effectively forming a lateral border for the femoral triangle.

Scarpa’s triangle outlines an important anatomical space that contains the femoral nerve, artery, and vein, which are vital for the blood supply and innervation of the lower limb. The sartorius muscle not only serves as a physical boundary but also plays a role in movements of the hip and knee.

In contrast, Poupart's ligament (also known as the inguinal ligament) is regarded as the superior boundary of the triangle, while significance in surgical and clinical context helps differentiate structures in this region. The axillary artery is associated with the upper limb and does not have a role in defining the femoral triangle, while the common carotid artery is related to the neck and head, far removed from the boundaries of the femoral triangle. Understanding these anatomical relationships is crucial for both clinical practice and anatomical studies in mortuary science and the respective educational framework.
