Hip flexor muscles

The video tutorial explains the iliopsoas muscle group, consisting of the iliacus and psoas major muscles. It covers their anatomical origins, insertions, and how they form the iliopsoas muscle. The tutorial details their function in hip flexion and their innervation, with the psoas major innervated by the L2 ventral ramis and the iliacus by the femoral nerve. The video concludes with a summary of the hip flexors' roles and connections.

Which two muscles make up the iliopsoas muscle group?

• Iliacus and psoas major
