Verified step by step guidance

Understand the anatomy of a newborn's skull: A newborn's skull contains fontanelles, which are soft spots made of connective tissue. These allow for flexibility during birth and accommodate brain growth after birth.

Compare this to an adult skull: In adults, the fontanelles have closed and fused into sutures, creating a rigid structure. This fusion typically occurs within the first few years of life.

Clarify the number of bones: A baby's skull has fewer bones because some bones that are separate at birth fuse together as the child grows. For example, the frontal bone starts as two separate bones and fuses into one in adulthood.

Eliminate incorrect options: An adult skull does not contain fontanelles, and a baby's skull is not fully fused at birth. These statements are anatomically inaccurate.

Select the correct answer: The key difference is that a baby's skull contains fontanelles, which allow for growth and flexibility during birth, whereas an adult skull does not.
