Muscles of abdomen
Musculi abdominis
Definition
The muscles of abdomen are a set of muscular structures forming the abdominal wall, playing a crucial role in protecting internal organs and managing intra-abdominal pressure. They also enable movements such as trunk flexion and rotation, while being involved in physiological functions like respiration, defecation, and urination.
They mainly consist of four groups: the rectus abdominal muscle, the external and internal abdominal oblique muscles, and the transversus abdominis muscle. The quadratus lumborum muscle is also found in this region.
