Question

select the correct answer.
tyler is admitted to the hospital after an accident. in the hospital, tyler overhears the doctor telling his mom that although he has a fracture in the axial skeleton, hes lucky because the bone doesnt protect any vital organ thats essential for survival. which bone has tyler fractured?
image of a skeleton with labels: skull (cranium), mandible (jaw bone), sternum (breast bone), ribs, vertebral column
a. mandible
b. rib
c. sternum
d. vertebral column

Explanation:

To solve this, we analyze the axial skeleton bones and their functions:

• Option A (mandible): The mandible is part of the axial skeleton. It is the jaw bone and does not protect any vital organs essential for survival.
• Option B (rib): Ribs protect vital organs like the heart and lungs, so this is incorrect.
• Option C (sternum): The sternum (breastbone) is part of the ribcage and protects vital organs (e.g., heart), so incorrect.
• Option D (vertebral column): The vertebral column protects the spinal cord, which is vital for survival, so incorrect.

Only the mandible fits the description of an axial skeleton bone that does not protect a vital organ essential for survival.

Answer:

A. mandible
