Which of the diagrams provided
outlines the structure of the axial skeleton?
The human skeleton can be divided
into two parts: the axial skeleton, which includes the skull, vertebral column, and
thoracic cage, and the appendicular skeleton, which includes the arms, legs, and
pectoral and pelvic girdles, or the attaching points of the arms and legs.
The axial skeleton is called such
because it is something of a fixed point, or axis, that the limbs move around, while
the appendicular skeleton consists of limbs, or appendages, that are added on to, or
appended to, the core axial skeleton. Therefore, the correct answer to
this question is Y. The diagram that shows the axial
skeleton is Y.
