What are the four boundaries of the femoral canal?

The correct answer accurately identifies the four boundaries of the femoral canal. The femoral canal is an anatomical space located within the femoral sheath in the groin region. It is crucial, especially in surgical contexts and for understanding potential hernias, as it is the site where femoral hernias can occur.

The boundaries of the femoral canal are defined as follows:

1. The inguinal ligament forms the superior boundary, providing a key landmark in the groin.

2. The lacunar ligament, which is an extension of the inguinal ligament, serves as the medial boundary, helping to stabilize the relationship between the femoral canal and surrounding structures.

3. The femoral vein constitutes the lateral boundary, forming the lateral aspect of the canal and allowing for venous return from the lower limb.

4. The iliacus and psoas tendons, which lie posteriorly to the femoral canal, contribute to its anatomical boundaries by anchoring the structures of the pelvis.

Understanding these boundaries is essential for surgical anatomy, particularly in procedures such as hernia repairs, where knowledge of the femoral canal can guide effective and safe intervention.
