Where is the pectoralis muscle located in relation to the trapezius muscle?

The pectoralis muscle is situated anteriorly to the trapezius muscle. The pectoralis major and minor muscles are located at the front of the chest, playing key roles in shoulder movement and stability. In contrast, the trapezius muscle, which is a large muscle extending down the back of the neck and upper spine, covers the upper back and shoulders. Therefore, since the pectoralis muscles are positioned towards the front of the body when compared to the trapezius, which lies more toward the back, they are described as anterior in relation to it. This clear distinction of location helps in understanding the functional anatomy and interactions of muscle groups in the upper body.
