Identify structures a–e in the following diagram of week 10 of development. (a) _______(c) _______(e) _______(b) _______(d) _______
The fetal period is (a) from weeks 9–38, (b) the time of rapid growth of body organs, (c) a time of cell differentiation, (d) all of the above, (e) none of the above.
Describe the development of reproductive organs in a fetus of each gender. Which
genes, gene products, and hormones are involved in the sex differences? Which sex-
related hormones are circulating in high concentrations in a pregnant woman
compared to a nonpregnant woman? Do these hormones cross the placenta (if you
are uncertain, consider hormone chemical class relative to membrane permeability to
make an educated guess)? Assuming these hormones do cross the placenta, how do
they affect the hormonal environment inside the fetus, and how does this relate to
fetal reproductive development?
