Which part of the skeleton includes bones of the upper and lower extremities?

Explanation:
The appendicular skeleton includes the bones of the upper and lower extremities, along with the shoulder and pelvic girdles that attach them to the body's core. This makes it the correct distinction because it specifically covers arms, legs, and their connecting joints, while the axial skeleton covers the skull, spine, and rib cage. The skeletal system is the whole framework of bones and joints, but when specifying the limbs, you’re talking about the appendicular portion. The nervous system is a separate system and not part of these skeletal categories.
