They act together, helping in flexing the hip joint.
iliopsoas is important for standing, walking, and running.

Answer 2

The great flexor muscle of the hip joint, divisible into two parts, the iliac and great psoas, -- often regarded as distinct muscles.

The psoas major, psoas minor and the iliacus muscles combine to become the iliopsoas. Psoas minor is present in roughly 40% of the population. If present, psoas minor assists in the superior rotation of the pelvis--an action oppsite to psoas major. Psoas minor is a vanishing muscle, disappearing as we evolve from a semi-flexed to an up-right being'. Psoas major and minor both insert on the lesser trochanter of the femur. They are considered part of the posterior abdominal wall due to their position and their role in cushioning the abdominal viscera.

Answer 3

The term Iliopsoas refers to the combination of three muscles:
psoas major
psoas minor
iliacus
These muscles are distinct in the abdomen, but usually indistinguishable in the thigh. As such, they are usually given a common name and are referred to as the "dorsal hip muscles"[1] or "inner hip muscles".[2]

Answer 4

It is a muscle in your pelvis/thigh
