What term describes the central part of the body, consisting of the head, neck, and trunk?

The term that describes the central part of the body, consisting of the head, neck, and trunk is "Axial." The axial skeleton serves as the central framework of the body. It includes the skull (head), vertebral column (neck and trunk), and rib cage. This central region is crucial for protecting vital organs such as the brain, heart, and lungs, as well as providing structural support and stability for the body.

In contrast, the appendicular skeleton refers to the limbs (arms and legs) and the structures that connect them to the axial skeleton. The term "limbs" specifically points to the arms and legs, while "proximal" is a directional term used to indicate that something is closer to the center of the body or the point of attachment. Therefore, "Axial" is the correct term for the central part of the body.
