42. How many days following conception does the human primitive streak form?
About 24 hours
3-4 days
13-14 days
About 3 weeks
V 5

43. c days
13 or 14 days after conception: A "primitive streak" appears. It will later develop into the fetus' central nervous system. This is the point at which spontaneous division of the blastocyst -- an event that sometimes generates identical twins -- is not longer possible. The pre-embryo is now referred to as an embryo. It is a very small blob of undifferentiated tissue at this stage of development.
