[[File:3D Tour of the Femoral Triangle.ogv|left|thumb|Video of relevant anatomy]]
The femoral triangle is important as a number of vital structures pass through it, right under the skin. The following structures are contained within the femoral triangle (from [[anatomical terms of location|lateral]] to [[anatomical terms of location|medial]]):
* [[Lateral cutaneous nerve of thigh]] - It crosses the lateral angle of the triangle, runs on the lateral side of the thigh and ends by dividing into anterior and posterior branches. The anterior branch supplies the anterolateral aspect of the thigh while the lateral branch supplies the lateral aspect of the gluteal region.<ref name="BD Chaurasia"/>
* [[Femoral nerve]] and its terminal branches - The nerve enters the femoral triangle by passing beneath the inguinal ligament, just lateral to the femoral artery. In the thigh, the nerve lies in a groove between iliacus muscle and psoas major muscles, outside the femoral sheath, and lateral to the femoral artery. After a short course of about 4&nbsp;cm in the thigh, the nerve is divided into anterior and posterior divisions, separated by lateral femoral circumflex artery.<ref name="BD Chaurasia"/> 
* Nerve to pectineus - This nerve arises from the femoral nerve just above the inguinal ligament. It passes behind the femoral sheath to reach the anterior surface of the pectineus muscle.<ref name="BD Chaurasia"/>
[[Femoral sheath]] encloses the upper 4&nbsp;cm of the femoral vessels. Its contents are shown below (from lateral to medial):
* Femoral branch of the [[genitofemoral nerve]] - occupies the lateral compartment of the femoral sheath along with femoral artery. It supplies the skin over the femoral triangle.<ref name="BD Chaurasia"/>
* [[Femoral artery]] and its branches - It emerges from the base of the femoral triangle at the [[mid-inguinal point]] (midpoint between the [[anterior superior iliac spine]] and the [[pubic symphysis]] of the [[pelvic bone]]) and exits through the apex of the triangle into the adductor canal.<ref name="BD Chaurasia"/>
* [[Femoral vein]] and its tributaries - The vein lies medial to the femoral artery at the base of the triangle but as it approaches the apex of the triangle, it lies posteromedially to the femoral artery. It receives drainage from [[great saphenous vein]], circumflex veins, and veins corresponding to the branches of the femoral artery here.<ref name="BD Chaurasia"/>
* [[Deep inguinal lymph nodes]] - It lies deep to the deep fascia, medial to the upper part of the femoral vein, inside the [[femoral canal]] (medial compartment of the femoral sheath). Cloquet's node (also known as Rosenmuller's node) also lies in this canal. It receives lymphatic drainage from superficial inguinal lymph nodes, lymphatic drainage from the [[glans penis]] or [[clitoris]], and from the deep lymphatics of the lower limb.<ref name="BD Chaurasia"/>
