On the back side, you have quadratus lumborum. Then you have external oblique, internal oblique and transverse abdominis muscles. Then you have that six pack muscle, called as rectus abdominis, in the center of the abdomen.
The muscle that extends from the ribs to the pubis and compresses the abdomen is the Rectus Abdominis, commonly known as the "abs" or "six-pack" muscles. It helps in flexing the spine and stabilizing the core during movements.
The rectus abdominis: flexes the trunk, compresses the abdomen and stabilizes the pelvis External oblique:unilaterally: contra lateral rotation and ipsilateral( same side) side bending Bilaterally: flexes the trunk, compresses abdomen, and stabilizes the pelvis Internal oblique: unilaterally, ipsilateral side bending and rotation Bilaterally: flexes trunk, compresses abdomen, and stabilizes the pelvis The transverse abdominis: unilaterally rotates the trunk ipsi laterally Bilaterally: compresses the abdomen
The rectus abdominis muscle compresses the abdominal contents when contracted. It is a paired muscle that runs vertically along the anterior abdominal wall and is responsible for flexing the trunk and assisting in forced exhalation.
The diaphragm is the muscle separating the abdomen from the chest
Hot or warm compresses are useful for soothing muscle aches and treating abscesses.
the diaphragm is the muscle separating the chest and the abdomen

The muscle that compresses the urinary bladder during micturition is the detrusor muscle. This smooth muscle layer surrounds the bladder and contracts to expel urine from the bladder into the urethra. The contraction of the detrusor muscle is primarily controlled by the autonomic nervous system, specifically the parasympathetic division.
The muscle that separates the chest from the abdomen and forms the floor of the thorax is called the diaphragm.
If you opened the abdomen of a crayfish you would see the intestine , flexor muscle and extensor muscle
The rectus abdominis muscle is located in the abdominal region of the body, running vertically along the front of the abdomen. It is commonly referred to as the "six-pack" muscle and is important for core stability and trunk flexion.
