Which muscles are included in the back muscle group?

The back muscle group specifically refers to a combination of muscles responsible for movements of the upper body, stabilization of the spine, and overall posture. The trapezius, latissimus dorsi, and spinal erectors form key components of this muscle group.

The trapezius is a large muscle that extends from the neck down to the middle of the back and across to the shoulder blades. It plays a critical role in moving, rotating, and stabilizing the shoulder blades.

The latissimus dorsi is a broad muscle that runs from the lower spine to the upper arms, contributing to actions such as shoulder adduction, extension, and internal rotation. This muscle is vital for many upper body movements and activities.

The spinal erectors, which include a group of muscles along the vertebral column, help maintain an erect posture and support the spine during movement. They are crucial for spinal extension and stabilization, protecting the spine during various physical activities.

In contrast, the other options mention muscles that belong to different groups: the quadriceps and hamstrings are primarily associated with the legs; the deltoids and pectorals are muscles of the shoulder and chest; while the biceps and triceps are muscles of the arms. None of these groups
