Final answer:

The core, rectus abdominis, gluteal group, and hamstrings are related to muscles mostly present in the anterior abdominal wall and lower body. These muscles work together to support the body's upright position, movement, and stability of the pelvis and spine.

Step-by-step explanation:

The core, rectus abdominis, gluteal group, and hamstrings are all related to the muscles that mainly work together to balance the body, allow for walking and running, and maintain posture.

Specifically, the rectus abdominis is one of the central muscles located on the anterior wall of the abdomen, known for giving the characteristic 'six-pack' appearance.

It is one of the four pairs of muscles that cover the anterior and lateral abdomen, serving to flex the spine and stabilize the pelvic region. The gluteal group, meanwhile, comprises the muscles that attach the leg to the pelvic girdle and are primarily responsible for the extension of the hip joint.

The hamstrings are located at the back of the thigh and are involved in bending the knee and extending the hip.

By controlling these muscles through a series of electrical impulses for contraction and relaxation, the brain maintains the body's upright posture and prevents any single muscle group from becoming excessively fatigued. If any muscle group fails to function properly, it can lead to compromised body posture.
