ILIACUS[edit | edit source]
The iliacus muscle is shaped like a triangle, flat and an exact fit of the iliac fossa — the curved surface of the largest pelvic bone. Together with the psoas major muscle, it is also called the iliopsoas muscle.
ANATOMY[edit | edit source]
Origin[edit | edit source]
Upper 2/3 of iliac fossa of ilium, internal lip of iliac crest, lateral aspect of sacrum, ventral sacroiliac ligament, and lower portion of iliolumbar ligament
Insertion[edit | edit source]
Lesser trochanter of femur. Its fibers are often inserted in front of those of the psoas major and extend distally over the lesser trochanter.
Nerve supply[edit | edit source]
The iliacus muscle is supplied with nerves by the branches of the second and third nerves of the lumbar area through the femoral nerve.(L2,L3)
Artery[edit | edit source]
