Each of these compartments has its own blood and nerve supply and contains a different group of muscles.
Cross section of femur. The central part of the bone is hollow and filled with marrow and the outer surface is covered by a layer of periosteum which is similar in structure to the perichondrium surrounding the cartilage. They insert together onto the lesser trochanter of the femur. The iliopsoas and pectineus muscles originate and attach in the.
The cortical bone equivalent area of the cross section of the region of interest femoral neck or shaft with all soft tissue voids trabecular and cellular spaces eliminated cm 2.

Proximally the head is well differentiated from the shaft and the greater trochanter by a marked constriction or neck. The periosteum or outside skin of the bone. A fractured femur should heal in about 10 weeks or so.
The psoas major is innervated by anterior rami of l1 3 while the iliacus is innervated by the femoral nerve. Many factors can affect the healing time including the health of the patient smokers and diabetics may heal more slowly and the type of femur fracture shaft fracture versus hip fracture versus fracture closer to the knee and the form of treatment may affect the healing time as well. The femur is the thigh bone the longest bone in the body.
In cross section the thigh is divided up into three separate fascial compartments divided by fascia each containing muscles. If we were to cut the femur bone in half we would see that it contains various layers. The hard compact bone.
It is much expanded at either extremity. Histology of the frog 131 by making a cross section of the femur. The femur is half as large again as the tibia.
