where is the iliopsoas muscle located in the body
Psoas major muscle The psoas major (/ˈsoʊ.əs/ or /ˈsoʊ.æs/) (from Greek: ψόας - psóās : 'of the loins', genitive singular form of ψόα - psóa 'the loins') is a long fusiform muscle located on the side of the lumbar region of the vertebral column and brim of the lesser pelvis. It joins the iliacus muscle to form the iliopsoas.
Lateral cutaneous nerve of thigh The lateral cutaneous nerve of the thigh is a nerve of the lumbar plexus. It arises from the dorsal divisions of the second and third lumbar nerves (L2-L3). 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 (ASIS). It then passes under the inguinal ligament, through the lacuna musculorum and then over the sartorius muscle into the thigh, where it divides into an anterior and a posterior branch.
