Question

Which of these bones/bony collections listed below is not part of the axial skeleton?

A) the skull
B) the sternum
C) the pelvis
D) the sacrum

Answer 1

C) The pelvis is not part of the axial skeleton; it is part of the appendicular skeleton, which is associated with the lower limbs.

Step-by-step explanation:

The bone which is not part of the axial skeleton is C) the pelvis. The axial skeleton consists of bones that form the central axis of the body and include the skull, vertebral column, rib cage, and associated bones.

Specifically, the axial skeleton includes the bones of the skull, vertebral column, thoracic cage, hyoid bone, and the ear ossicles in the middle ear.

The pelvis, in contrast, forms part of the appendicular skeleton and is associated with the lower limbs.
