 # Greatest amount of cranial growth occurs by:

a) Birth to five years 

b) 5 - 6 years

c) 6 - 7 years 

d) 7 - 10 years

The correct answer is: A. Birth to five years.

The greatest amount of cranial growth occurs from birth to five years of age. During this time, the skull undergoes rapid growth and development to accommodate the growing brain and other structures. This period of growth is known as the rapid growth phase.

After the age of five, the rate of cranial growth slows down, and the skull undergoes more subtle changes as the child ages. While there may be some additional growth from 5-10 years of age, it is not as significant as the growth that occurs during the first five years of life.
