What term describes the part of the body that includes the limbs?

The term that describes the part of the body that includes the limbs is the appendicular region. This region specifically refers to the appendages or limbs of the body, which comprise the arms and legs, as well as the girdles that attach them to the torso, namely the shoulder girdle (pectoral girdle) and the pelvic girdle.

The appendicular region is contrasted with the axial region, which consists of the head, neck, and trunk. Understanding this distinction is crucial in anatomy, as it helps in identifying and referencing specific areas of the body correctly. The core, while integral to various body functions, does not encompass the limbs but rather refers to the central part of the body, primarily the muscles around the torso. The peripheral region, while it denotes areas away from the center of the body, is not as precise as "appendicular" for describing limbs specifically. Thus, the appendicular region is the accurate term for the limbs' anatomical classification.
