The rectus abdominis is the muscle that vertically extends from the 5th, 6th, and 7th ribs to the pubis. It helps the flexion of the spinal column and controls the tilt of the pelvic region. The rectus abdominis plays a key role in exercises that require bending motions and it also aids in stabilizing your upper body while performing movements with your arms and/or cephalic region.
The Rectus Abdominis helps your posture.
The sternocleidomastoid muscle is superior to the rectus abdominis muscle. The sternocleidomastoid is located in the neck, while the rectus abdominis is situated in the anterior abdominal wall. Therefore, in terms of anatomical position, the sternocleidomastoid is positioned above the rectus abdominis.
