Which term describes the body region that consists of the arms and legs?

• A. Axial
• B. Appendicular
• C. Abdominal
• D. Thoracic

Answer: (B)

The body is organized into two main regions: the axial region, which covers the head, neck, and trunk, and the appendicular region, which includes the limbs and the girdles that connect them to the trunk. The arms and legs belong to the appendicular region, so the term that describes that body region is appendicular. The axial region contains the skull, spine, and ribcage, not the limbs; the abdominal area is part of the trunk within the axial region, and the thoracic region refers to the chest area, also part of the axial skeleton.
