GROSS ANATOMY

Detailed explanation-1: -The average circumferences of the iliopsoas muscle–tendon complex were 68 mm, 58 mm, and 46 mm, respectively, whereas those measures for the tendinous portion were 27 mm, 31 mm, and 27 mm respectively.

Detailed explanation-2: -The iliopsoas is classified as an “anterior hip muscle” or “inner hip muscle". The psoas minor does contribute to the iliopsoas muscle. The inferior portion below the inguinal ligament forms part of the floor of the femoral triangle.

Detailed explanation-3: -The iliopsoas musculotendinous unit (IPMU) is the primary flexor of the thigh with the ability to add and extra-rotate the coxofemoral joint. If the latter is fixed, the contraction of the iliopsoas muscle flexes the trunk and inclines it from the contraction side.[1] The muscles can act separately.

Detailed explanation-4: -Some key iliopsoas facts The iliopsoas is the strongest hip flexor. It is the primary muscle responsible for an important movement: walking. It is intimately related to the convergence of tissues and structures often referred to as “the core”. It spans more joints in the body than any other muscle.
