Muscles Of The Abdominal Wall

The external oblique is a muscle that helps with rotating the trunk and flexing the spine. Rectus abdominis is the muscle responsible for forming the 'six-pack abs' and mainly helps with flexing the trunk. Pectoralis major is a large chest muscle, and deltoid is a shoulder muscle.

The External Oblique muscle is responsible for torso rotation and is located on the sides of the abdomen. Rectus Abdominis is responsible for flexing the torso, Deltoid is a shoulder muscle, and Gluteus Maximus is a buttock muscle.

The Internal Oblique is a muscle in the abdominal wall that lies underneath the External Oblique. It is responsible for rotating and bending the trunk.

The Transverse Abdominis is the deepest of the abdominal muscles and plays a key role in stabilizing the core.

The Rectus Abdominis is a paired muscle that runs vertically on each side of the anterior wall of the abdomen. It is commonly known as the 'six-pack' muscle due to its appearance in individuals with low body fat.

The transversus abdominis muscle is responsible for compressing the abdomen and aiding in flexion of the body at the lumbar region. The incorrect answers do not describe the specific function of this muscle.

The correct answer describes the actions performed by the muscle, which are compression of the abdomen and flexion of the body at the lumbar region. The incorrect answers provided refer to actions carried out by different muscles or joints, not by the muscle in question.

The rectus abdominis muscle primarily functions to compress the abdomen, which helps in various activities like breathing, coughing, and bowel movements.
