The pectoral region, also known as the chest, is a vital anatomical area located in the upper front part of the body. It includes the pectoral muscles, which consist of two main groups: the pectoralis major and pectoralis minor. The pectoralis major is the larger of the two and is responsible for movements of the arm, such as adduction (bringing the arm towards the body) and medial rotation (inward rotation). The pectoralis minor lies underneath the pectoralis major and aids in stabilizing the shoulder and elevating the ribs during breathing.

The pectoral region also encompasses other important structures like the sternum (breastbone), which protects vital organs like the heart, and the clavicles (collarbones), which help stabilize the shoulder girdle. Additionally, the region contains lymph nodes and blood vessels that play a crucial role in immune response and circulation. The pectoral region's anatomy is fundamental to various upper body movements and contributes significantly to overall strength and functionality.
