The erector spinae
The coccygeus muscle extends from the coccyx to the ischial spine, which is part of the hip bone. It provides support to the pelvic organs and assists in functions like defecation and childbirth. Contraction of the coccygeus muscle can help tilt the coccyx forward.
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.
