74. At which of the following ages does fetal movement first occur?

A. 1 month B. 2 months

C. 4 months D. 6 months E. 7 months


The correct answer is B. Neuromuscular development is sufficient to allow fetal movement in the

eighth week of life. Other features of Week 8 include the first appearance of a thin skin, a head as

large as the rest of the body, forward-looking eyes, appearance of digits on the hands and feet,

appearance of testes and ovaries (but not distinguishable external genitalia), and a crown-rump length

of approximately 30 mm. By the end of the eighth week, nearly all adult structures have at least begun to 

develop, and the fetus "looks like a baby."
