====== FEMORAL ARTERY ======


    * Origin
      * It is the continuation of external iliac artery. It begins behind the inguinal ligament at the midinguinal point
    * extent and course
       * passes downwards and medially
         * first in femoral canal
         * then in adductor canal
           * at the lower end
             * passes through an opening in adductor magnus
                * to become continuous with popliteal arteery
    * in the femoral triangle
      * relations
        * anteriorly
           * Skin, superficial fascia, deep fascia and the anterior wall of the femoral sheath.
        * posteriorly
           * Psoas major, the pectineus, and the adductor longus. The posterior w all of the femoral sheath intervenes between these structures and the artery
        * medially
           * Just below the inguinal ligament the femoral vein is medial to the artery.
           * However, the vein gradually crosses to the lateral side to lie posterior to the artery
           * it is directly behind the artery at the apex of the femoral triangle, arid lateral to the lower end of the artery
        * laterally
           * The femoral nerve is lateral to the upper part of the artery. Lower down the artery is related to the branches of the nerve.
  * branches
    * The femoral artery traverses the triangle from its base at the midinguinal point to the apex. In the triangle, it gives off six branches, three superficial and three deep branches
    * profunda femoris artery
    * deep external pudendal artery
    * muscular branches
