Question

question 29
the c2 vertebra (the axis) is:
○ a long bone
○ a short bone
○ a flat bone
○ an irregular bone

Explanation:

Bones are classified by shape. Long bones (e.g., femur) have length > width. Short bones (e.g., wrist) are cube - like. Flat bones (e.g., skull) are thin/flat. Irregular bones have complex, non - standard shapes. The C2 (axis) vertebra has a unique, irregular structure (e.g., dens), so it is an irregular bone.

Answer:

D. an irregular bone
