Voorbeelden van iliacus

• The iliacus originates on the iliac fossa on the interior side of the pelvis.

• Of these, only iliacus is attached to the pelvis (the iliac fossa).

• It is joined by the iliacus, psoas major forms the iliopsoas which is surrounded by the iliac fascia.

• The iliacus originates on the iliac fossa to join psoas at the iliopubic eminence to form the iliopsoas which is inserted into the lesser trochanter.

• The psoas is the primary hip flexor, assisted by the iliacus.

• Pain on walking that confines the patient to bed indicates possible cancer adherence to or invasion of the iliacus muscle.

• The iliacus originates on the iliac fossa of the ilium.

• Though the iliopsoas is sometimes considered a member of the anterior compartment muscles, the iliacus and the psoas portions do not share the same innervation.

• It emerges from the lateral border of the psoas major just inferior to the iliohypogastric, and passes obliquely across the quadratus lumborum and iliacus.

• Here the tendon of the psoas major muscle passes over the medial chamber and the tendon of the iliacus muscle runs over the lateral chamber.

• It is slightly concave from side to side, convex from before backward, and gives attachment to a few of the fibers of the iliacus.

• Between the adductor magnus and the vastus medialis four muscles are inserted: the iliacus and pectineus above; the adductor brevis and adductor longus below.

• The hamstrings, adductor magnus and gluteus maximus work concentrically in the legs, while the psoas major, iliacus, and rectus femoris work eccentrically keeping the hip in neutral extension.

• The iliopsoas consists of psoas major (and occasionally psoas minor) and iliacus, muscles with separate origins but a common insertion on the lesser trochanter of the femur.

• It emerges from the lateral border of the psoas major at about its middle, and crosses the iliacus muscle obliquely, toward the anterior superior iliac spine.
