A “skeleton person” refers to the human skeletal system, which is the rigid internal structure that supports the body and protects internal organs. It consists of 206 bones in adults, including the skull, spine, ribs, and limbs. The skeleton provides shape and structure to the body, serves as a framework for muscle attachment, and allows movement. It also protects vital organs, produces blood cells in the bone marrow, and stores minerals like calcium. The term “skeleton person” is often used to describe the appearance of a human’s skeletal system, especially in contexts like anatomy, Halloween, or when referring to a very thin individual.
