Femoralregion
The femoral region refers to the anatomical area of the thigh, specifically the part of the upper limb of a bipedal organism extending from the hip to the knee. It is primarily characterized by the presence of the femur, the longest and strongest bone in the human body. This region contains significant musculature, including the quadriceps femoris group on the anterior side, responsible for knee extension, and the hamstrings on the posterior side, which facilitate knee flexion and hip extension. The femoral triangle, a key anatomical landmark, is located in the superoanterior part of the femoral region. Its boundaries are formed by the inguinal ligament superiorly, the sartorius muscle laterally, and the adductor longus muscle medially. The floor of this triangle is composed of the iliopsoas and pectineus muscles. Within the femoral triangle, the femoral artery, femoral vein, and femoral nerve are found, making it a crucial area for vascular access and surgical procedures. The skin and subcutaneous tissue of the femoral region house superficial lymphatic vessels and veins, such as the great saphenous vein. The deeper tissues include the fascia lata, a strong investing fascia, and the intermuscular septa that divide the thigh into anterior, posterior, and medial compartments. These compartments contain distinct muscle groups with related functions and innervation. The femoral region plays a vital role in locomotion, weight-bearing, and maintaining posture.
