The flat and triangular iliacus muscle, an exact fit of the iliac fossa is located in the lower portion of the trunk.
"The psoas muscles originate at the sides of the lower vertebrae (in your spine) and run down through the pelvis, where it joins the iliacus (another hip flexor) and attaches to the femur or thigh bone," explains Dana Aaron, an advanced clinician at the Weill Cornell-affiliated Hospital for Special Surgery's Sports and Performance Center.
The LFCN is a pure sensory nerve that originates from the L2 and L3 spinal nerve roots, travels downward lateral to the psoas muscle, and passes the iliacus muscle diagonally towards the anterior superior iliac spine (ASIS).
iliacus, and muscles of diaphragm] and their fascia are the members of this region.
Active isotonic and isometric strengthening exercises were prescribed to strengthen the frontal abdominal muscles (musculus obliquus externus abdominis, musculus obliquus internus abdominis, musculus rectus abdominis), deep abdominal muscles (musculus psoas major, musculus psoas minor, musculus iliacus, musculus quadratum lumbarum), and back muscles (musculi dorsi, musculus erector spinae, musculi transverso-spinales, musculi inter-spinales, musculi intertransversarii).

Twelve muscles (tibialis anterior, soleus, medial gastrocnemius, lateral gastrocnemius, rectus femoris, vastus lateralis, vastus medialis, semimembranosus, biceps femoris long head, adductor magnus, iliacus, and gluteus maximus) on the right leg of each subject were recorded, with symmetry being assumed for the other leg.
Thus, data obtained from the four pelvic markers, Left Anterior Superior Iliacus (LASI), Right Anterior Superior Iliacus (RASI), Left Posterior Superior Iliacus (LPSI), and Right Posterior Superior Iliacus (RPSI), were used to calculate vertical displacements of the pelvis during turning.
1: vastus medialis muscle; 2: rectus femoris muscle; 3: vastus lateralis muscle; 4: adductor longus muscle; 5: tibialis anterior muscle; 6: peroneus longus muscle; 7: patellar tendon; 8: pes anserinus bursae; 9: popliteous muscle; 10: iliacus muscle; 11: quadrates lumborum muscle; 12: supraspinous ligaments, area between L5-S1 and S1-S2; 13, 14: extensor digitorum brevis; 15: extensor hallucis longus; 16: flexor halluces longus; C: deltoids.
The interval between the hip abductors and abdominal musculature was identified and carried down to the iliac crest where the iliacus was released from the iliac bone.
The samples were collected from the following species of birds: Taiga Bean Goose (Anser fabalis johanseni), Siberian Thrush (Geokichla sibirica), Song Thrush (Turdus philomelos), Fieldfare (Turdus pilaris), Redwing (Turdus iliacus), Black-Throated Thrush (Turdus atrogularis), Common Tern (Sterna hirundo), Green Sandpiper (Tringa ochropus), Common Greenshank (Tringa nebularia), Red-Throated Flycatcher (Ficedula albicilla), Temminck's Stint (Calidris temminckii), and Dusky Warbler (Phylloscopus fuscatus).
