Verified step by step guidance

Understand that the erector spinae muscle group is a key component of the deep back muscles responsible for extending and stabilizing the spine.

Recall that the erector spinae muscle group is divided into three main components: Iliocostalis, Longissimus, and Spinalis. These muscles run longitudinally along the spine.

Differentiate the erector spinae group from other muscle groups mentioned in the options. For example, the trapezius, latissimus dorsi, and rhomboid major are superficial back muscles, not part of the erector spinae group.

Recognize that the rectus abdominis, external oblique, and internal oblique are abdominal muscles, not associated with the erector spinae group.

Confirm that the semispinalis, multifidus, and rotatores are part of the transversospinalis group, which lies deeper than the erector spinae group and is involved in fine motor control of the spine.
