A lateral boundary of a femoral hernia also includes which of the following?

In the context of femoral hernias, the lateral boundary is composed of anatomical structures surrounding the femoral canal, which serves as the primary pathway for femoral hernias to occur. The femoral canal is located medial to the femoral vein and is bordered laterally by the femoral sheath containing vascular structures and the femoral nerve.

Understanding that femoral hernias develop through the femoral canal highlights the significance of this structure in hernia formation. The femoral canal itself is a potential space that can become a site for the herniation of abdominal contents, which is why identifying it as a boundary is critical in understanding the anatomy involved in this type of hernia.

Other anatomical structures mentioned, such as the inguinal canal and the vascular sheath, do not serve as lateral boundaries of a femoral hernia; thus, they are less relevant in this context. The inguinal canal is involved with inguinal hernias, while the vascular sheath contains vessels and is not classified as a direct boundary for a femoral hernia. The obturator canal is located more medially and does not directly relate to the femoral canal's lateral boundary.
