 Given that the femoral triangle is a 3D space containing some important anatomical structures, think of it as a pyramid. The mnemonic sail helps us to remember the lateral, medial and superior borders, that's Sartorius, a Dr. Longus, and the Inguinal ligament, but there's also a floor and a roof to this 3D triangle. Let's get rid of this 2D image and bring in some 3D elements now. We've got the femur there, Sartorius, a Dr. Longus, the Inguinal ligament, and then down the back Pectoneus and Iliosaurus. The floor of the femoral triangle is made up by the body of a Dr. Longus, the body of Pectoneus, and a little bit of Iliosaurus as well. Then the floor of the femoral triangle is made up by a Dr. Longus, Pectoneus, and Iliosaurus. The roof is made up by the fascialata, which is the border of the main fascial compartment of the thigh. You'll know it from the tensor fascialata, a muscle which stretches it out on the lateral side. There's a little hole up here in the fascialata, which is called the saphenous opening. The greater saphenous vein pops through there. And of course the femoral triangle is open up the top to allow in its contents. We'll take out the Inguinal ligament and bring them in here. So lateral, we have the femoral nerve. Next we have a fascial compartment called the femoral sheath, which contains the femoral artery, femoral vein, and the femoral canal. The femoral sheath ends by blending in with the adventitia of these vessels, around four centimetres below the Inguinal ligament. The femoral canal ends earlier up here. It contains one single lymph node. After entering the femoral triangle, the femoral nerve divides into branches which supply the muscles nearby with innovation. That's the quads, sartorius, and pectoneus. It spits out anterior cutaneous branches to supply sensory innovation for the medial thigh and knee. And its saphenous branch supplies the medial lower leg. The femoral artery and vein slink down together along the bed of adducta longus and magnus. And once they're past the border of sartorius there, out of the femoral triangle and into the adducta canal. Effort lymphatic vessels coming out of the node in the Inguinal canal then make up the deep inguinal lymph nodes of the thigh. So that's it for the femoral triangle. Catch you next video for more info on the femoral canal. As always, thanks for watching and we'll see you next time.
