The term 'Like the Oblique Muscle' refers to the ABDOMINAL muscle, which is a nine-letter word. The ABDOMINAL muscle is a large, flat muscle located in the abdomen that helps with breathing, posture, and movement. It is composed of four parts: the external oblique, internal oblique, transverse abdominis, and rectus abdominis. The external oblique is the most superficial layer of the ABDOMINAL muscle and is responsible for side bending and rotation of the trunk. The internal oblique lies beneath the external oblique and is responsible for the same movements as the external oblique, but in the opposite direction. The transverse abdominis is the deepest layer of the ABDOMINAL muscle and is responsible for compressing the abdomen and stabilizing the spine. Lastly, the rectus abdominis is the most visible layer of the ABDOMINAL muscle and is responsible for flexing the spine.
