Question

Which of the following statements is/are true of the growth of the skeleton?
A) It begins to ossify at eight weeks of gestational age.
B) All bone formation ceases immediately after the end of adolescence.
C) Calcification of bones does not occur until an infant begins to learn to walk.
D) All of the answers are correct.
E) None of the answers are correct.

Accepted Answer

The growth of the skeleton begins very early in embryonic development, and ossification (the process of bone formation) begins at around eight weeks of gestational age.

Answer: E 
 None of the statements are completely true. Bone formation continues throughout adulthood and calcification of bones actually begins in utero. Additionally, the statement about the cessation of bone formation after adolescence is false, as bones continue to remodel and repair throughout adulthood.
