The femoral nerve is the major nerve supplying the anterior compartment of the thigh. It is the largest branch of the lumbar plexus, and arises from the dorsal divisions of the ventral rami of the second, third, and fourth lumbar nerves (L2, L3, and L4).
Trochanteric fossa: Posterior branch of obturator nerve (L5-S2) Nerve supply. The pectineus is the only adductor muscle that is innervated by the femoral nerve.
It is bounded medially by the internal/lesser trochanter and anterior branch of the ventral femoral ridge, and often less distinctly bounded laterally as the greater trochanter and posterior branch of the ventral ridge are highly reduced or absent. [3]
A trochanter is a tubercle of the femur near its joint with the hip bone. In humans and most mammals , the trochanters serve as important muscle attachment sites. Humans have two, sometimes three , trochanters.
The highest point of the greater trochanter is located higher than the collum and reaches the midpoint of the hip joint. The greater trochanter can easily be felt. The trochanteric fossa is a deep depression bounded posteriorly by the intertrochanteric crest on medial surface of the greater trochanter. Anterior and superior to the trochanteric ...
The iliopsoas gets innervation from the L2-4 nerve roots of the lumbar plexus which also send branches to the superficial lumbar muscles. The femoral nerve passes through the muscle and innervates the quadriceps, pectineus, and sartorius muscles. It also comprises the intermediate femoral cutaneous and medial femoral cutaneous nerves which are ...
The trochanteric anastomosis is an anatomical structure [1] that provides circulation around the head of the femur. It includes the superior gluteal artery and the medial and lateral circumflex femoral arteries (the former of which provides the main supply to the femur ).
Greater trochanter is labeled at right. The greater trochanter of the femur is a large, irregular, quadrilateral eminence and a part of the skeletal system. It is directed lateral and medially and slightly posterior. In the adult it is about 2–4 cm lower than the femoral head. [1]
