Final answer:
During a retroperitoneal exam, muscles such as the psoas major, iliacus, and quadratus lumborum are identified, which contribute to stabilizing the body and supporting posture.
Step-by-step explanation:
The muscles identified during a retroperitoneal exam include the psoas major and iliacus muscles, as well as the quadratus lumborum muscle. These muscles help form the posterior abdominal wall and play a key role in stabilizing the body and maintaining posture.
The psoas major and iliacus are often referred to collectively as the iliopsoas, which is important for flexing the hip and stabilizing the lower back. The quadratus lumborum is involved in lateral flexion of the vertebral column and also aids in movements of the femur.
During a retroperitoneal exam, the muscles identified include the posterior abdominal muscles. These muscles form the posterior wall of the abdomen and are responsible for stabilizing the body and maintaining posture. They include the quadratus lumborum, psoas major and iliacus muscles, and parts of the ilia of the hip bones.
